23、ne layers intimately bondedtogether. The pipe for this specification is termed a PE-AL-PE composite pipe.3.2.3 pipe hoop stressfor simplicity the value of the hoop stress quoted assumes a homogeneous wall. Local values of stresswill vary with the different layers (see 3.2.3.1).3.2.3.1 DiscussionThic
24、k walled plastic pipes produced from one material have hoop stresses that vary through the wall, and are usually describedby the Lame Theory. The composite nature of the PE-AL-PE pipe, composed of materials with very different Youngs Modulusvalues, will, on pressurization, not have a uniform stress
25、distribution through the thickness of the wall of the pipe. The PE-AL-PEpipes have a hoop stress distribution that differs substantially from both the thick and thin walled pipe cases.4. Pipe Classification4.1 Pipe DiameterThe PE-AL-PE composite pipes are classified by outside diameter.4.2 Pipe Dime
26、nsion RatioThe concept of dimension ratio is not relevant to PE-AL-PE laminated pipes, and cannot be usedto relate pressure rating with total wall thickness.5. Materials5.1 GeneralThe PE-AL-PE pipe is composed of one metallic layer, two layers of the same polymeric polyethylene meltadhesive and two
27、layers of the same polyethylene.
