19、lu-minum, melt adhesive, and polyethylene layers intimatelybonded together. The pipe for this specification is termed aPE-AL-PE composite pipe.3.2.3 pipe hoop stressfor simplicity the value of the hoopstress quoted assumes a homogeneous wall. Local values ofstress will vary with the different layers
20、 (see 3.2.3.1).3.2.3.1 DiscussionThick walled plastic pipes producedfrom one material have hoop stresses that vary through thewall, and are usually described by the Lame Theory. Thecomposite nature of the PE-AL-PE pipe, composed of materi-als with very different Youngs Modulus values, will, onpressu
21、rization, not have a uniform stress distribution throughthe thickness of the wall of the pipe. The PE-AL-PE pipes havea hoop stress distribution that differs substantially from boththe thick and thin walled pipe cases.4. Pipe Classification4.1 Pipe DiameterThe PE-AL-PE composite pipes areclassified
22、by outside diameter.4.2 Pipe Dimension RatioThe concept of dimension ratiois not relevant to PE-AL-PE laminated pipes, and cannot beused to relate pressure rating with total wall thickness.5. Materials5.1 GeneralThe PE-AL-PE pipe is composed of onemetallic layer, two layers of the same polymeric adh
23、esive andtwo layers of the same polyethylene.
