FIGURE 1 FLOWTITE® COMPOSITE MATERIAL
3.1 Manufacturing Standards
Australian Flowtite® products are designed to fulfil the requirements of the latest Australian
standards for GRP pipes:
AS 3571.1 – Plastics piping systems – Glass reinforced thermoplastics (GRP) systems based on unsaturated polyester (UP) resin. Part 1: Pressure and non-pressure drainage and sewerage (ISO 10467:2004, MOD)
AS 3571.2 – Plastics piping systems – Glass reinforced thermoplastics (GRP) systems based on unsaturated polyester (UP) resin. Part 1: Pressure and non-pressure water supply (ISO 10639:2004, MOD)
RPC Pipe Systems has advised that water supply and sewerage pipes and fittings will be
manufactured using standard RPC orthophthalic polyester resin and E or ECR glass with
all pressure pipes and fittings complying with AS 3571.1 and AS 3571.2. In regards to the
choice of glass, ECR glass will be provided for all sewerage pipes whereas water supply
pipes may be supplied in E or ECR glass.
Flowtite® GRP pipe is internal diameter controlled and therefore the external diameter may
vary slightly during the production process. At least 30% of manufactured pipes will comply
with spigot dimensional tolerances over the entire barrel length. These pipes will be
identified as “adjustment pipe” (See pipe marking example in Appendix ‘A’) and may be
used as cut pipe on site. The tolerance on the outside diameter of the pipe does not
exceed the spigot diameter by more than 2 mm for smaller diameter pipes (diameters
≤1200 mm) and 5 mm for larger diameters. This tolerance should not pose any operational
risk when using mechanical couplings, tapping bands and repair clamps given that most
accommodate a range of pipe outside diameters.
3.2 Nominal Size
(Ref: Clause 4.1.2 of AS 3571.1 and AS 3571.2)
Nominal sizes of Australian Flowtite® products range from DN 300 to DN 3000:
The dimensions of Flowtite® pipe generally conform to the ISO "B1" Series (i.e. outside
diameter pipe spigot controlled) providing interchangeability with other pipes in common
use in Australia such as GRP pipes to AS 3571, PVC pipes to AS/NZS 1477 Series 2 and
ductile cast iron pipes to AS/NZS 2280 CIOD.
Flowtite® pipe, in the range DN 300 to DN 750 are manufactured with spigot dimensions as
specified in AS 3571.1 and AS 3571.2 Series B1 (Table 5) in Appendix ZZ, are generally
compatible with the outside diameter dimensions of ductile iron pipe and fitting for pressure
applications to AS/NZS 2280.
When specifying the use of ductile iron fittings with GRP pipes, care should be taken to
ensure their dimensional compatibility with the GRP pipe.
WSAA Product Appraisal PA 1211 Issue 4 9

Other ISO or ASTM pipe sizes are available if required.
NOTES:
1 Reference to AS/NZS 1477 (PVC-U) also infers equivalent sizes of AS/NZS 4765 PVC-M and AS/NZS 4441
PVC-O.
2 Refer appendix D for actual sizes.
3.3 Nominal Stiffness Classes
(Ref: Clause 4.1.3 of AS 3571.1 and AS 3571.2)
The standard nominal pipe stiffness classes available will be SN 5000 and SN 10000 i.e.
Series S1 of the ISO standards although other stiffness classes can be manufactured.
Stiffness values of SN 20000 have been manufactured in Australia.
3.4 Nominal Pressure
(Ref: Clause 4.1.4 of AS 3571.1 and AS 3571.2)
The nominal pressure class for Australian urban water industry Flowtite® products will be
PN 16, although pressure classes in the range from PN 1 to PN 35 can be manufactured.
The basis for Flowtite® pressure pipe design is the performance requirements of AWWA
C950 (latest edition), which stipulates a minimum factor of safety of 1.8 on the predicted 50
year pressure strength of the pipe, and a minimum of 4 for initial burst strength.
Note: Flowtite® pipe can withstand an occasional transient pressure spike (water hammer)
of up to 140% of the nominal pressure rating e.g. a 1400 kPa transient pressure in a PN 10
rated pipe. However, the steady state operating pressure in a PN 10 pipe should not
exceed 1000 kPa.
3.5 Lengths
3.5.1 Nominal length
(Ref: Clause 5.1.3.1 of AS 3571.1 and AS 3571.2)
Although the winders for Flowtite® pipe are capable of producing any pipe length from 3 to
21 m, the nominal length is limited by factory layout and practical aspects, such as
transportation.
The maximum standard nominal length of Flowtite® pipe manufactured at Lonsdale is 13 m.
Lengths of 3m and 6 m are also available, although pipe lengths >13 m cannot be
hydrostatically pressure tested. Flowtite® pipe of other lengths can also be supplied for
special orders.
3.5.2 Laying length
(Ref: Clause 5.1.3.2 of AS 3571.1 and AS 3571.2)
The total length of each pipe is equal to the nominal length with a tolerance of ±25 mm.
The laid pipe length is equal to the total length plus 10 mm (width of centre register of the
socketed coupling).
3.6 Load Capacity Values
(Ref: Clause 5.2 of AS 3571.1 and AS 3571.2)
Tables for hoop and tensile load capacity are available in the Flowtite® GRP Pipe and
Fittings Engineering Design and Installation Guide.
3.7 Pipe Fittings and Accessories
(Ref: Clause 6.1 of AS 3571.1 and AS 3571.2)
Flowtite® pipe fittings are moulded or fabricated using the same materials that are used to
produce the Flowtite® pipe. Fittings are supplied with spigot ends to suit the Flowtite®
double socketed coupling.
The standard range of fittings includes:
WSAA Product Appraisal PA 1211 Issue 4 10
COPYRIGHT
Double bell or socketed couplings.
Bends, 11¼º, 22½º, 45º, and 90º with spigoted or flanged ends.
Tees, either equal or reduced with spigoted or flanged ends. Eccentric tees and flanged nozzles can be manufactured to order.
Reducers, concentric or eccentric with spigoted or flanged ends.
End caps.
Y’s and other fittings can be manufactured to order.
Manhole couplings connectors with or without puddle flanges.
See also the Flowtite® GRP Pipe and Fittings Engineering Design and Installation Guide.
3.8 Materials
3.8.1 Reinforcement
(Ref: Clause 4.2.2 of AS 3571.1 and AS 3571.2)
The Lonsdale plant uses E or ECR-glass to manufacture pipes for water supply and
sewerage. ECR-Glass is a requirement for all sewer application whereas E or ECR glass
can be used for water applications. Flowtite® has provided technical data sheets for the
selected glass reinforcements that are approved by Amiantit for use in Flowtite® pipes
showing compliance with ISO 2078. Both chopped strand and continuous rovings are used
to provide both longitudinal and hoop strength.
3.8.2 Resin
(Ref: Clause 4.2.3 of AS 3571.1 and AS 3571.2)
The Lonsdale plant manufactures Flowtite® pipes using orthophthalic polyester resin EPS 1
supplied by Allnex (formerly Nuplex Industries of Australia) to an Amiantit specification.
The Flowtite® Purchase Acceptance Standard (PAS) requires that the heat distortion
temperature of the cured resin, when tested in accordance with ISO 75-2, should be at
least 75°C, which allows a maximum operating temperature with standard orthophthalic
resin of 55°C.
Other resins are available for specialized applications such as higher temperatures.
3.8.3 Aggregate and fillers
(Ref: Clause 4.2.4 of AS 3571.1 and AS 3571.2)
Sand is used as filler in Flowtite® pipes. The Flowtite® PAS requires that less than 3% of
the sand have particles larger than 0.71 mm and no particles be larger than 1 mm. The
sand is sourced locally from a deposit in the Adelaide region. The locally sourced sand
results in an “almost white’ pipe unlike other GRP products common to the Australian water
industry.
3.8.4 Pipe coupling
(Ref: Clause 4.2.6 of AS 3571.1 and AS 3571.2)
The standard pipe jointing system is a Flowtite® double socketed coupling which utilises
EPDM elastomeric REKA sealing gaskets and an elastomeric centre register to keep pipe
spigot ends from touching. The couplings are produced on the same winder as the pipe,
featuring a special design, which facilitates the milling process. The REKA gaskets are
imported from a seal manufacturer in the United Arab Emirates that supplies the Amiantit
manufacturing plant in Dammam, Saudi Arabia or from a seal manufacturer in India which
supplies to the Amiantit European plants. Seals up to DN 600 are moulded, while those
above are spliced and vulcanized.
WSAA Product Appraisal PA 1211 Issue 4 11
COPYRIGHT
Couplings are machined in a special machine which mills grooves in the coupling cylinders
using diamond-tipped tools. The REKA gaskets and elastomeric centre register are
designed to sit in machined grooves with the REKA gaskets in each end of the coupling to
seal against the spigot surface. RPC Pipe Systems claim the REKA gasket has been in
use for more than 75 years. The REKA Coupling Qualification Test Report (with diagrams)
is included in Appendix ‘E’.
The amount of angular deflection is diameter dependent, ranging from 3.0o for DN 300
down to 0.5o for ≥ DN 1900. For proper sealing of the REKA gasket, especially for pressure
classes of up to PN 32, a smooth, dimensionally accurate outside spigot surface is needed
on each end of the pipe. Flowtite® has developed equipment which chamfers the edge of
the pipe to avoid damage to the rubber gaskets, while simultaneously milling the external
surface. This equipment rotates the pipe and mills both ends using water-cooled diamond-
tipped tools.

3.8.5 Wall construction
(Ref: Clauses 4.3.1 to 4.3.3 of AS 3571.1 and AS 3571.2)
The wall of Flowtite® pipes is built with several layers (see Figure 1):
interior surface layer and liner;
inner structural layer (skin);
core;
outer structural layer (skin); and
exterior surface layer.
The interior surface layer of the pipe is resin rich and depending on the pipeline application
may include glass or polyester veil. The liner is built with resin and chopped glass fibres.
The structural layers are comprised of the inner skin, core and outer skins. The skins
contain continuous hoop rovings, resin and chopped glass, while the core contains sand
fillers additionally.
The exterior surface layer, or outer layer, is resin rich and depending on the pipeline use
may contain glass or polyester veil.

RPC Pipe Systems has submitted the Flowtite® GRP pipe systems for appraisal by the
Australian Water Industry as a fully tested, quality assured product, with documented case
histories (both local and international) and certified engineering standards.
Much of the following information was prepared by RPC Pipe Systems in response to
questions resulting from the initial appraisal.
6.2.1 Mechanical characteristics
6.2.1.1 Initial specific ring stiffness – Batch release test
(Ref: Clause 5.2.1 of AS 3571.1 and AS 3571.2)
The initial stiffness of Flowtite® pipes is designed to be above the nominal values in all
cases. Initial stiffness is part of daily quality control in all Flowtite® factories. If during
quality control the stiffness is measured to be less than the nominal the product is rejected
and downgraded to the next lower stiffness class. The test procedure is Flowtite ® Test P
202, which is based on ISO 7685 as nominated in AS 3571.1 and AS 3571.2.
Testing of pipes produced during commissioning and ongoing manufacture has indicated
that initial specific ring stiffness meets the requirements of the ISO product standards.
A copy of test results for a pipe DN1000, SN5000, PN6 which was tested on 11 April 2016
shows the pipe met the requirements specified in ISO 10467.
Accepted.
6.2.1.2 Long-term specific ring stiffness (S50) – Type test
(Ref: Clause 5.2.2 of AS3571.1 and AS3571.2)
The long-term specific ring stiffness of Flowtite® pipe was checked using the long-term
creep stiffness method in accordance with ISO 10468 and analysed according to ISO
10928, method B, measuring deflection for approximately 12000 hours.
The tests are conducted in the Flowtite laboratory in Sandefjord. A type test report for a
section of DN600 PN10 SN5000 FP2.1 pipe produced by RPC Pipe Systems, confirms that
the pipe fulfils the requirements of the ISO standard.
The long-term specific ring stiffness of Flowtite® pipe has been measured in creep
according to ISO 1928 and reported by Flowtite® (nominated Test report T-2012-201) as

Accepted.
6.2.1.4 Ultimate long-term resistance to failure in a deflected condition – Type test
(Ref: Clause 5.2.4 of AS 3571.1 and AS 3571.2)
The ultimate long term resistance to failure in a deflected condition has been conducted on
Flowtite® pipes in accordance with ISO 10471 and ASTM D-5365.
A test for ultimate long-term resistance to failure in a deflected condition was conducted on
FP2.1 pipes produced by RPC Pipe Systems. The test samples were 300 mm long rings,
DN600, PN10, SN 5000, produced on the Flowtite continuous winder atLonsdale, South
Australia.
A total of fourteen samples were tested in accordance with ASTM D5365 and ISO 10471.
Amiantit analysis of the results reports that by deflection according to ISO 10471 it gives a
deflection of 18.9%, which compared with the 11.3% requirement for SN5000 in Table 12
of ISO 10639 shows good compliance. Refer test report T-2014-158 R1.
Accepted.
6.2.1.5 Initial specific longitudinal tensile strength – Batch release test
(Ref: Clause 5.2.5 of AS 3571.1 and AS 3571.2 - Specifies ISO 8513:2000 test procedure)
Testing for the initial specific longitudinal tensile strength is part of daily quality control in
all Flowtite® factories. The test procedure is Flowtite® Test method P 205, which is similar
to ISO 10466. The minimum initial axial strength values are shown in Table D4 of Appendix
D Product not complying with these requirements is rejected and downgraded to the next
lower pressure class.
Comparison with Table 14 in AS 3571.1 and AS 3571.2 reveals that the Flowtite products
fulfil the requirements.
Testing of pipes produced during commissioning and ongoing manufacture has indicated
that initial specific tensile strength meets the requirements of the ISO product standards.

6.2.1.6 Initial design and failure pressures for pressure pipes – Batch release test
(Ref: Clause 5.2.6 of AS 3571.1 and AS 3571.2 Specifies ISO 8521:1998 test procedure)
Testing for the apparent initial circumferential tensile strength is part of routine quality
control in all Flowtite® factories. The test procedure is Flowtite® Test methods P 207a and
P 207b, which are similar to ISO 8521 method D and method B, respectively as nominated
in AS 3571.1 and AS 3571.2. The projected average initial strength values are shown in
Appendix D, Table D5.
A copy of test results for a pipe DN1000 PN6 SN5000 which was tested on 11 April 2016
shows the pipe met the requirements specified in ISO 10467.
Accepted.
6.2.1.7 Long-term failure pressure – Type test
(Ref: Clause 5.2.7 of AS 3571.1 and AS 3571.2 – Specified ASTM D2992 and EN 1447 test procedure)
The Flowtite® pressure classes comply with the long term failure pressure requirements as
specified in Clause 5.2.7 of AS 3571.1 and AS 3571.2. The nominal pressures are based
on long term (50 year) strain values determined by testing with appropriate factors of
safety. A type test for long-term failure was conducted on pipe manufactured by RPC Pipe
Systems in Lonsdale, South Australia. A total of 20 samples were tested of DN600 PN10
SN5000 FP2.1. Refer test report T-2012-199 HDB Test.
Accepted.
6.2.1.8 Resistance of pressure pipes to cyclic internal pressure – Type test
(Ref: Clause 5.3 of AS 3571.1 and AS 3571.2 – Specifies ISO 15306 test procedure)
The resistance of Flowtite® pipes to cyclic internal pressure up to 1 million pressure cycles
has been verified through testing. RPC Pipe Systems has submitted a test report
summarised as follows:
IMA Dresden Test Report “Cyclical Internal Pressure Tests on Flowtite® GRP Pipes” (dated
13/05/2013) reported cyclic pressure testing of DN300 PN10 SN10000 pipes manufactured
by Flowtite® licensee Amitech Germany GmbH. Testing was conducted in accordance with
ISO 15306. The specimens were tested at the rate of 25 cycles per minute for one million
cycles between 0.75 x PN and 1.25 x PN. Refer test report B409/12.1.
Long term cyclic pressure testing of Flowtite pipes is not routinely performed as the pipes
typically operate below their endurance strain limit and, therefore, are not affected by the
cyclic pressure. The testing carried out in the past is still valid as the same strain limit s are
still used in Flowtite GRP pipes. As Flowtite GRP pipes are designed using a strain basis
these tests are valid for the full range of pressure classes and diameters.
Accepted.
6.2.1.9 Resistance to strain corrosion – Type test
(Ref: Clause 5.4 of ISO 10467 – Specifies ISO 10952 test procedure)
The strain corrosion resistance of Flowtite® pipes has been measured at 0.66% (see
Flowtite® test report T-2011-205 at www.flowtite.com). Using the equation in Clause 10.6 of
ISO 10952 as specified in ISO 10467 Clause 5.4.2.1, this value can be converted to
deflection and compared with the requirement. By using the thickest of the pipes in each
stiffness class the following deflections are obtained:
WSAA Product Appraisal PA 1211 Issue 4 16
COPYRIGHT
Stiffness SN 2500 SN 5000 SN 10000
Deflection, % 14.3 11.3 9.0
Comparing these values with the requirements in Table 17 of ISO 10467 shows that these
requirements are met.
Type testing of 24 samples of DN600 PN10 SN5000 FP2.1 pipe manufactured by RPC
Pipe Systems has been conducted. After 10,000 hours the extrapolated strain at 50 years
was 0.88% equivalent to a 14.1% defection. This exceeds the requirement of 11.3% from
ISO 10467. Refer to test report T-2012-198 R2.
Accepted.
6.2.1.10 Elastomers – Type test
(Ref: Clause 4.2.6 of AS 3571.1 and AS 3571.2)
In accordance with the Flowtite® Purchase Acceptance Standards (PAS), Flowtite® GRP
pipe elastomeric joint sealing materials have been shown to have met the following
requirements:
EPDM - EN 681-1:1996, for type WA (cold potable water supply [up to 50ºC]) and WC (cold
non-potable water supply, drainage, sewerage and rainwater pipes for continuous flows up
to 45ºC and intermittent flows up to 95ºC).
SBR - ASTM F-477
The Reka coupling used to join Flowtite® GRP pipe is fitted with an EPDM (hardness 55)
elastomeric multiple lip type seal. The centre register is also EPDM (hardness 60). SBR
compounds may be used as an alternative to EPDM. The test report T-93-102-V,
illustrating the seal and centre register, is included in Appendix ‘A’.
Accepted.
6.2.1.11 Joint performance – Type test
(Ref: Clause 7 of AS 3571.1 and AS 3571.2)
Flowtite® pipes are designed for flexible or rigid jointing and with or without end-load
resisting capability.
Clause 7.2.4 covers "Flexible non-end-load-bearing joints with elastomeric sealing
rings” and a submitted test report Test Report T-2012-125 which shows compliance
with Clause 7.2.4.
A qualification test according to EN 1119. ISO 8639 and ASTM D4161 for a Flowtite
DN600 PN10 FPC flexible joint was performed, using the guidelines of the accredited
Flowtite test procedure.
The coupling was a DN600, PN 10 Flowtite FPC coupling, produced by Amitech Germany
and machined Amitech Poland. The pipes were DN600, PN10 Flowtite FP 2.1
specifications. The pipe was produced in Poland.
The joint was tested with ΔD=3.5mm.
Clause 7.3 covers Wrapped non-end-load-bearing joints and a submitted test report Test
Report Test Report T-2004-127 which shows compliance with Clause 7.3.
Clause 7.4 covers bolted non-end-load-bearing joints and a submitted test report Test
Report Test Report T-2012-125 which shows compliance with Clause 7.3.
The test reports show that in all cases the joints fulfil the requirements specified in the ISO
Standards.
Accepted.
WSAA Product Appraisal PA 1211 Issue 4 17

Clause 7.2.5 covers "Flexible end-load-bearing joints with elastomeric sealing rings”. At the
time of report preparation, only test reports older than 10 years are available confirming
compliance of Flowtite end load bearing joints with Clause 7.2.5.
To be confirmed.
6.2.1.12 Abrasion resistance
Ref: DIN 19565
RPC Pipe Systems has supplied a copy of the Flowtite® Test Report No. T-97-113-B,
Abrasion Resistance Test. This test report describes an abrasion resistance test program
using the Darmstadt rocker test procedure (Ref DIN 19565) performed on DN 600, PN 10,
SN 5000 Flowtite® pipes. The average abrasion loss was found to be 0.34 mm / at 100,000
cycles (See page 10 in the Flowtite® GRP Pipe and Fittings Engineering Design and
Installation Guide.
The abrasion resistance of an individual pipeline material is difficult to determine because
test methods do not duplicate the varied abrasion conditions in sewers. Many comparative
Darmstadt rocker tests have resulted in a performance rating for plastics pipe materials
that exceeds other harder pipe materials. The test results indicate minimal wear and a
calculated life expectancy well beyond the requirements of most water agencies.
Accepted.
6.2.1.13 Temperature and pressure re-rating
Temperature and pressure re-rating is described in the Flowtite® GRP Pipe and Fittings
Engineering Design and Installation Guide and nominates 35ºC and below as requiring no
pressure re-rating. Re-rating is required for temperatures 36ºC to 50ºC and further re-
rating for temperatures 51ºC to 70ºC.
Accepted.
6.2.1.14 Resistance to ultraviolet degradation
Flowtite® technical data states that there is no evidence to suggest that ultraviolet
degradation is a factor that affects the long term service life of Flowtite® pipes. The
exposed outermost surface will be affected by discoloration and in the longer term glass
fibres will be exposed. If desired, the external surface of the Flowtite® pipe may be painted
with two part urethane paint compatible with GRP. However, this will become an item
requiring ongoing maintenance.
Accepted.
6.2.1.15 Other technical data
Summaries of the following design data and production testing are included in the Flowtite ®
GRP Pipe and Fittings Engineering Design and Installation Guide:
Strain corrosion testing
Hydrostatic pressure testing
Note: Many international and national standards for GRP pressure pipe require the
manufacturer to factory hydrostatic test pipe before shipment. In support of these
requirements, Flowtite® has designed equipment to accommodate hydrostatic testing of
both the pipe and couplings to twice the rated pressure (for all diameters through DN
3000).

Flowtite® sewer pipe has been designed to meet the performance criteria established in
ASTM D3262. Pipes intended for use in gravity sanitary sewer systems will meet the
chemical requirements of ASTM D3262, which includes a minimum long-term deflection
(strain) requirement when exposed to 5% sulphuric acid. Other requirements of this
specification include axial tensile strength and hydrostatic soundness.
Note: The information provided by RPC Pipe Systems and included in this Section (6.2.1) have been cross
referenced with the AS 3571.1 and AS 3571.2 notation (not mathematically checked) by the Appraisal Project
Manager and found to be consistent.
Accepted.
6.2.2 Effect on water quality – Type test
(Ref: Clause 4.8 of ISO 10639)
AS 3571.2 requires compliance with regulations on the quality of drinking water in force at
the location where the components are to be used.
RPC Pipe Systems have submitted samples of pipe, coupling and gaskets to AWQC
laboratories for testing to AS/NZS 4020. This testing was completed successfully and final
reports appear in Appendix E.
Accepted.
6.3 WSAA Agency Network Requests
Other than specifying the requirement for conformance and Type Testing to AS 3571.1 and
AS 3571.2 the network asked the questions as set out below and RPC Pipe Systems has
provided the following answers:
Q 1. Please confirm that Flowtite® flanged connectors can be provided compatible with the
Australian water industry standard sizes to AS 4087, Figure B5.
Answer: The thickness of flanges meets the requirements of BS 4994. The drilling pattern
or PCD of all flanges will comply with that required by AS 4087 Figures B1, B2, B5 and B7.
Q 2. Please provide details of the pipe construction layers with special reference to the
inner liner / layer thickness(s) for sewerage in relation to wear and corrosion.
Answer: The thickness of each layer will depend on the fluid being transported, installation
requirements and pressure ratings.
Q 3. For pipes that are cut in the field, what action must the constructor undertake to
ensure the spigot ends of the cut pipes are suitable for jointing?
Answer: Each Flowtite pipe is assessed for dimensional compliance along its full length
during the manufacturing process. Pipes that meet spigot dimensional tolerances along
the entire barrel are identified as ‘adjustment pipe’ (see pipe marking example in Appendix
‘A’). Constructors only need to chamfer the cut ends before jointing. Pipes that only meet
spigot dimensional tolerances at each end will require field machining and chamfering
before jointing if they are cut. Generally there is no reason why a constructor who
manages his pipe stocks diligently will need to field machine cut pipes given that at least
WSAA Product Appraisal PA 1211 Issue 4 19
COPYRIGHT
30% - 70% of pipes will be “adjustment pipes” suitable for field cutting without the need for
machining.
Sealing of the cut ends of the pipe is not required as demonstrated by extensive testing of
the Flowtite product. Long term pressure and strain corrosion testing are carried out with
the cut ends untreated.
Q 4. Are there any limitations on the under-pressure cut-in connection of Flowtite pressure
pipe using flanged off-take clamps and the use of repair clamps?
Answer: Flowtite pipes cannot be directly tapped but will require either tapping band or
mechanical flanged off-take clamp, depending on the diameter of the service connection.
The under pressure cut-in performed in accordance with the method described in WSA
03:2011 Appendix C – Under Pressure Cut-in-Connections to Pressure Pipe ≥ DN80 can
be carried out successfully on GRP pipe using a diamond impregnated shell cutter of the
appropriate diameter.
Mechanical flanged off-take clamps complying with Water Industry Standard for Flanged
Off-take clamp WSA 122:2009 Issue 1 are recommended.
Mechanical flanged off-take clamps rated PN16 are available as Type F and Type R. Type
F flanged off-take clamps that are designed for application to flexible pipes with pressure
classifications ranging from PN9 to PN16, should be specified.
Q 5. Please provide recommendations for drilling and tapping Flowtite pressure pipes,
particularly the smaller sizes (≤ DN 375).
Answer: RPC Pipe Systems has provided a 12 page “TAPPING PROCEDURE FOR
FLOWTITE FP PIPES HOT AND COLD TAPPING. This document is included in Appendix
‘I’.
Q 6. Is Flowtite® pipe suitable/available for slip lining (rehabilitation) and pipe jacking? If it
is please provide details of the joint used for lining and jacking.
Answer: Flowtite® Pipe has been successfully used for slip lining applications. Flowtite®
pipe intended for direct bury applications is not suitable for jacking applications. Jacking,
microtunnelling and slip lining pipe is available and the subject of PA 1322.
Q 7. Please confirm that Flowtite® pipe can be manufactured in outside diameter sizes
compatible with AS/NZS 2280 – Ductile iron pressure pipes and fittings – to enable
Australian ductile iron fittings to be used.
Answer: Australian manufactured Flowtite® pipes in accordance with AS3571.1/AS3571.2
Table 5 which is compatible with AS/NZS 2280 ductile iron fittings.
Q 8. Please provide information on the quality certification for RPC Pipe Systems Pty. Ltd.
with regard to quality management systems (AS/NZS ISO 9001:2008) and your future
intentions regarding product certification for the Flowtite® pipe and fittings manufactured in
Adelaide.
Answer: RPC Pipe Systems is certified to ISO 9001:2008. Certificate number QEC23699.
Since the change of ownership of the company Product Certification has been given
priority and is current being sought. Long term type testing has not been completed but is
currently underway. Preliminary results show good correlation with Flowtite long term
data.
Q 9. Please advise transportation arrangements for Flowtite® pipes and fittings.
Answer: Flowtite GRP pipes will be packaged in scalloped timbers to protect the pipes and
keep them stable during transportation. Pipes are packed into bundles to facilitate easy
and safe unloading on site.
WSAA Product Appraisal PA 1211 Issue 4 20
COPYRIGHT
Q 10. Please advise what appearance acceptance criteria will be used for inspection
and batch release of Flowtite® pipes and fittings?
Answer: Appendix ZC of AS3571.1 and AS3571.2 is used as the acceptance criteria.
Q 11. What are the intentions of RPC Pipe Systems with respect to the manufacture
of fittings?
Answer: RPC Pipe Systems manufactures a full range of fittings to suit the pipe sizes and
pressure classes manufactured by the Lonsdale, SA, plant.
Q 12. The Australian water industry has experienced incidences of osmotic blistering
of the internal corrosion barriers (gel-coats) of other GRP pipes and to address that issue
has developed requirements that limit the type of resin to orthophthalic polyester with
specified properties. What comments does RPC Pipe Systems make with respect to this
issue?
Answer: RPC Pipe Systems is unaware of any incidences of osmotic blistering with
Flowtite pipe. Our technical experts advise that osmotic blistering is primarily caused by
the PVA binders used on some types of glass reinforcement, which forms acetic acid in
service which migrates to the resin interface where through a process of osmosis blisters
form. The E and ECR glass used in the manufacture of Flowtite® pipes and fittings uses no
such binders. In addition, osmotic blistering can be caused by poor material choice and
poor workmanship. The continuous advancing mandrel process used by Flowtite produces
a well compacted and cured laminate which eliminates osmotic blistering.
Q 13. Can RPC pipes and fittings be colour coded?
Answer: The Flowtite® pipe manufacturing process can accommodate the incorporation of
a coloured thread within the outer layers of the pipe or the use of pigmented resin (such as
purple) for colour coding pipes. Coloured threads have been used successfully for
identification of multiple pressure classes on a single site whereas pigmented resin has
been used to identify recycled water pipelines. Either the thread or pigmenting has the
advantage of the colour being encapsulated within the wall of the pipe ensuring permanent
identification.
Q 14. It is understood that the Code letter "R" is marked on the pipe to indicate that
the pipe is suitable for axial loading. This infers there is also pipe which is not suitable for
axial loading. Please comment.
Answer: The normal Flowtite pipe has been designed to be used with a rubber ring joint.
Therefore the axial loads on the pipeline are reduced compared to a fully welded or
restrained joint pipeline as each pipe is effectively isolated from loadings on adjacent
pipes. The Flowtite pipe has sufficient axial strength (in accordance with
AS3571.1/AS3571.2) to resist handling and soil loads. However, it is not suitable for
restrained joints where longitudinal loads are high.
Where the joints are required to be fixed, such as in high pressure process pipe work, a
specially designed Flowtite pipe can be manufactured on the same equipment with more
reinforcement in the longitudinal direction. This type of pipe has been successfully
manufactured in Australia by RPC Pipe Systems for use in desalination plants and other
process plants.

12 DISCUSSION
The RPC Pipe Systems Lonsdale plant was the 13th in a series of standard ‘turn -key’
manufacturing plants that have been successfully constructed and commissioned
throughout the world. There are now 22 plants constructed around the world. There is
reasonable justification for being confident that the Lonsdale plant is capable of producing
pressure and non-pressure pipes and fittings to meet ISO standards in sizes suitable for
the Australian and New Zealand water industries.
As a licensed Australian manufacturer of an international product, RPC Pipe Systems has
been able to present considerable information on Flowtite® GRP pipe and fittings to
demonstrate a mature, widely used, tested and proven product range. The technical data

13 SUMMARY
Australian made Flowtite® GRP pipe and fittings are manufactured to comply with the
dimensional, material and performance requirements of AS 3571.1 and AS 3571.2 with
some additional sizes and specific testing requirements to suit Australia and NZ. The
documented international experience and expertise presented by RPC Pipe Systems and
Amiantit / Flowtite® as well as local experience provides evidence to consider Flowtite®
GRP pipe and fittings will be “fit-for-purpose” products for use by the Australian water
industry.
14 LIFE EXPECTANCY
Based on the product information provided, the international reputation of the product and
subject to design, installation and commissioning in compliance with the manufacturer’s
instructions and relevant WSAA Water Supply and Gravity Sewerage Codes, Flowtite®
GRP pipe and fittings (FS and FP) could be expected to achieve an ‘A’ rating – Life
expectancy in excess of 100 years before major rehabilitation. This rating would be
conditional on the future work items being completed and should only be considered a
general guide to life expectancy and may increase or decrease as a result of the quality of
installation, system operating conditions, operating environment and other geographical
and site specific factors.
15 FUTURE WORKS
There are no future works items.
15.1 Recommendations
It is recommended that WSAA members accept/authorise of Flowtite® GRP pipe and
fittings for water supply and sewerage, subject to the design, installation and
commissioning being in accordance with specifications provided by RPC Pipe Systems and
relevant WSAA Water Supply and Gravity Sewerage Codes..
