Butt-welding ends shall be in accordance with figure 1 for wall thickness up to 20.0 mm; for thicker walls, refer to figure 2. The inside diameter at the welding end shall be equal to that of the pipe on which the valve shall be welded. If a welding end of a valve has a thickness not equal to the pipe with which it is intended to be used, the welding end preparation at the joint has to be in conformity with fig. 3.

NPS Tolerance of inside diameter at bevel end (1) (mm)

2" - 10"

12" - 48"

+ 1.6

+ 2.4

(1) Tolerance refers to variation from specified ID calculation by (OD spec. - 2t spec). OD = outside diameter t = wall thickness

The out-of roundness at a welding end, defined as the difference between the maximum and the minimum inside diameter at the welding pipe end shall not exceed 1% of the specified inside diameter.

The length of the butt end shall be sufficient to allow welding and heat treatment without damage of the internal parts of the valve. If Purchaser/Engineer accepts design which do not meet this requirement, than Manufacturer shall inform the Purchaser/Engineer about the precautions which needs to be fulfilled in order to guarantee that during welding of the butt welding ends no damage shall occur to the seat. These precautions shall be highlighted by the Manufacturer in the erection and installation instruction book.

� Double block and bleed : design of a valve with two seating surfaces between which the cavity can be vented through a bleed connection and thus confirm the tightness of the valve, at least in closed position, when pressure is applied to any side or both sides of the valve.

� Double piston effect : when the pressure is applied to one side, let us say "upstream" side, and when upstream ball seat is leaking, transfer pressure shall have a positive shut-off effect on the downstream seat (acting, for instance, on the back face of this seat) and thus reinforcing the global tightness of the valve.

� Anti-static design : all ball valves shall be fitted with anti-static device conforming to BS 5351.

� Stem retention (anti blow-out) : In conformity with BS 5351 valve shall be designed with an anti blow-out stem so that the stem cannot be fully ejected by pressure inside the valve with the stem packing, gland retainer bolting removed.

� Secondary seat and stem sealing : all ball valves NPS 6" shall be fitted with a secondary stem sealing and all ball valves greater or equal to NPS 8" shall be fitted with a secondary seat and stem sealing. This system permits an injection of sealant and shall be fitted with an integral check valve. The number and the location of sealing points shall be on the Manufacturer's responsibility.

Purchaser is allowed to request the check of this system design and its operation, specially for modified or new valve model.

� Actuator shall be able to produce 150% of the mechanical power (couple, translation force, etc…) required to open the valve form the fully closed position and under the required maximum design differential pressure of the valve and perform the travel under the required stroke time.

The manual operating device shall be safe, normally de-clutched and thus shall not move when actuator is in operation. A de-clutching device, generally a lever, shall permit a safe manual operation without any influence of a remote signal : manual operation shall have the full priority over motorised operation during the whole de-clutching duration.

Moreover, when required, local motorised operation shall also be possible, to open or close the valve, by means of push button(s) generally. Electrical actuators shall always be equipped with these local, motorised operation devices.

� The required failure position of the valve, as mentioned in the data sheet (generally fail as it is) shall be guaranteed as soon as one of the following supply is lost :

� gas or air for pneumatic or gas-over-oil actuators

� electrical power supply for electrical actuators (causes always "fail as it is" position).

� Actuator shall be equipped with local position indicators and position limit switches (open/closed) for remote indication.

� When required in the data sheet, actuator shall be equipped with a positioner in order to receive a remote proportional signal for intermediate position of the valve.

A sequential number to differentiate two or more piping classes of the same rating and same material butpresenting some differences related to the handled fluid.

Fourth part

A letter designating the underground:

l U = Underground

1.2. Wall Thickness

The wall thickness of pipe shall be as follows:

Wall thickness of pipe shall be calculated as specified in the applicable sections of:

l ANSI B 31.8 for classes covering the main process and auxiliary gas lines.

l ANSI B 31.3 for classes covering utilities lines.

1.3. Corrosion Allowance

The minimum corrosion allowance used to calculate wall thickness as follows:

l Carbon steel and ferritic alloys in classes calculated following ANSI B 31.8 : 1.6 mm

l Carbon steel and ferritic alloys in classes calculated following ANSI B 31.3 : 1.6 mm

l Stainless steel : 0 mm

l Plastic and FRP pipes: 0 mm.

1.4. Wall Thickness Calculation

a) Pipes for gas application have to comply with ASME/ANSI B 31.8 code. Pipe wall thickness will becalculated as follows :

t = nominal wall thickness (mm)

P = design pressure (MPa)

S = minimum yield strength (MPa)

D = nominal outside diameter (mm)

F = design factor = 0.4

E = longitudinal joint factor

T = temperature derating factor = 1.0

C = corrosion allowance (mm)

b) Pipes for utilities lines have a wall thickness complying with ASME/ANSI B 31.3 code :
