19、 of the alu-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 differe

20、nt layers (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,
