Overview of WSAA The Water Services Association of Australia (WSAA) is the peak body of the Australian urban water industry. Its members and associate members provide water and wastewater services to approximately 16 million Australians and to many of our largest industrial and commercial enterprises.

Urban water service providers have a critical role in ensuring that Australians have access to adequate and high quality water services. As Australia’s population continues to grow, with most of this growth occurring in cities, that role becomes increasingly important.

WSAA’s vision is for Australian urban water utilities to be valued as leaders in the innovative, sustainable and cost effective delivery of water services. WSAA strives to achieve this vision by promoting knowledge sharing, networking and cooperation amongst members. WSAA identifies emerging issues and develops industry-wide responses. WSAA is the national voice of the urban water industry, speaking to government, the broader water sector and the Australian community.

1 EXECUTIVE SUMMARY

Wang Components (WANG) ‘Vari-Tap’ ductile iron tapping saddles in sizes DN 100 and DN 150 with 20 mm or 25 mm female threaded BSP off take were appraised for compliance with AS/NZS 4793-2009 Mechanical tapping bands for waterworks purposes.

The DN 100 and DN 150 WANG ‘Vari-Tap’ can be assembled in two different configurations and are suitable for rigid (Type R) or flexible (Type F) applications.

In the ‘Type F’ configuration the WANG Vari-Tap, designated ‘Type F’, is designed for application on Series 2 flexible pipes with pressure classifications PVC-U ≥ PN 9, PVC-M ≥ PN 12 and PVC-O ≥ PN 16.

In the ‘Type R’ configuration the WANG Vari-Tap, designated ‘Type R’, is designed for application on rigid pipes only, typically ductile iron (DI), grey cast Iron (CI) or asbestos cement (AC).

The body component of the WANG Vari-Tap consists of two segments, both manufactured from ductile iron casting and protected by a fusion bonded epoxy coating. The ductile iron castings are coated to the requirements of AS/NZS 4158:2005-Thermal-bonded polymeric coatings on valves and fittings for water industry purposes.

The top and back segments are configured to the desired designation (Type F or Type R) and bolted together with 316 stainless steel bolts, nuts and washers to form a tapping saddle suitable for rigid (Type R) or flexible (Type F) applications. A watertight connection is achieved through the use of a combination hydrostatic lip / compression seal around the connection into the pipeline. The nitrile rubber seal compound is fully compliant with the requirements of AS 1646:2007 Elastomeric seals for waterworks purposes.

Wang Components is nominated as the licencee holder of the Standards Mark Licence Certificate No SMK00278 to AS/NZS 4793, issued by SAI Global for the range of mechanical tapping saddles, described in Clause 3 and 4 of this report.

Wang Components sources its supply of raw ductile iron castings for the WANG Vari-Tap body segments from a ISO 9001 certified ductile iron casting supplier The supply of raw castings is to Wang Components drawings and specifications.

Castings supplied to Wang Components manufacturing facility in Wangaratta, Victoria are inspected and tested for compliance with AS/NZS 4793 and Wang Components quality production procedures.

The polymeric coating is applied by Wang Components approved coating applicator.

Based on the information available and the successful performance under the nominated type test regime this product has been rated ‘A’ with a life expectancy in excess of 100 years. This rating is only a general guide to life expectancy and may increase and decrease as a result of the system operating conditions, preventative maintenance programs, operating environment or other geographical and site features.

Wang Components and their suppliers operate under quality management systems certified to AS/NZS ISO 9001:2008.

1.1 Recommendation It is recommended that WSAA members and associates accept/authorise WANG Vari-Tap tapping saddle, listed in the StandardsMark Schedule referenced in Appendix ‘A’ that are relevant to water supply, recycled water and sewer pressure pipelines provided pipeline design, installation, acceptance testing and commissioning are in accordance with applicable WSAA Codes, WSAA member integrated Codes and the manufacturer’s requirements, where specified.

3 THE PRODUCT The WANG Vari-Tap tapping saddle provides a means for the connection of property services to reticulated network pipelines with allowable operating pressures up to 1600 kPa (PN16).

The WANG Vari-Tap is designed with two segments that can be assembled together to form a tapping saddles suitable for rigid (Type R) or flexible (Type F) applications.

When configured to Type R, the saddle is suitable for application on rigid pipes that are within the defined 10mm range of the product. Refer to Table 1.

When configured to Type F, the saddle forms a full circle, fixed diameter fitting suitable for flexible pipes with an outside diameter matching the fixed diameter of the saddle. The WANG Vari-Taps are only suitable for Series 2 PVC pipe diameters. Refer to Table 2.

The WANG Vari-Tap is constructed from ductile iron casting that is protected by a fusion bonded epoxy coating designed for and commonly used in Australian the water industry.

The halves are held together with 316 stainless steel bolts, nuts and washers, with the nut coated with molybdenum-disulphide to prevent galling during installation.

A watertight connection is achieved through the use of a combination hydrostatic lip / compression seal around the connection into the pipeline. The nitrile rubber seal, that is fully compliant with the requirements of AS 1646, also provides resistants to contaminants such as oils, diesel and other hydrocarbons.

As tuberculation inserts are not suitable for under pressure cut-in connections, the WANG Vari-Tap is not supplied with these inserts.

10 PRODUCT WARRANTY The WANG Vari-Tap is covered by normal commercial and legal requirements of the Competition and Consumer Act 2010, which covers manufacture to the relevant Standard.

11 LIFE EXPECTANCY Subject to the mechanical tapping saddle installation being in accordance with the manufacturer’s requirements and the relevant WSAA Codes the following life expectancy ratings can be expected for the different applications, before major rehabilitation or replacement.

• ‘A’ for water supply – with polymeric coating to AS/NZS 4158, life expectancy in excess of 100 years before major rehabilitation or replacement.

• ‘B’ for pressure mains conveying “typical” sewage – with polymeric coating to AS/NZS 4158, life expectancy in excess of 50 years before major rehabilitation or replacement. Typical sewage is considered to be non-saline, with pH >6.0 and a TDS less than <1500mg/L. Specialist materials advice should be sought for sewage compositions outside this “typical” guideline composition limits.

These ratings are only a general guide to life expectancy. The rating may increase or decrease as a result of care exercised during installation, system operating conditions, operating environment and other geographical and site-specific factors.

12 WATER AGENCY EXPERIENCE WITH THE PRODUCT OR FIELD TESTING REPORT

As this is a new product design, Tyco Water is not aware of any performance monitoring or independent assessment that has been performed on the WANG Vari-Tap.
