Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope*1.1 This specification covers the polyethylene material a
3、nddimensions applicable to flange adapters (FAs) used to connectpolyethylene pipes to other flanged pipe and components suchas valves and flanged fittings. This standard describes outsidediameter controlled polyethylene (PE) pipe flange adapters(FAs) in diameters ranging from34 in. through 65 in. (1
4、2 mmthrough 1600 mm). The flange adapters may be manufacturedby various methods including injection molding, compressionmolding, and machining from billet or thick-wall polyethylenepipe.1.2 The flange adapter (FA) is the principal component ofthe lap-joint flanged assembly widely used for several de
5、cadesin low-pressure to high-pressure polyethylene pipe systems forall types of pressurized flow (gas and liquid) applications. Theflange adapters physical shape consists of the pipe-like Neckwhich is monolithic with its Hub. The Neck is intended to bebutt-fused or fusion coupled to the pipe-line; w
