31、 form a composite structure. The PEencapsulation is not for protecting the steel from corrosion damage. The minimum PE thickness of 0.012 in. at the thinnest point still maintains the bondbetween the steel and PE. The pipe is designed to combine pipe stiffness and buckling performance. The thickness
32、 of the HDPE encapsulation does notaffect product performance.6.

The pipe wall shall not have cracks, holes, blisters, voids, foreign in
33、clusions or other defects that arevisible to the naked eye and that can affect the wall integrity or the bonding to the steel reinforcement. Holes deliberately placedin perforated pipe are permitted. The surface shall be free of bloom.6.2 Pipe Dimensions and Tolerances:6.2.1 Pipe Dimensions (for bot
34、h perforated and non-perforated pipe) shall comply with Table 1, Table 3, and Table 4 forsingle-wall and double-wall pipe and Table 2 for triple-wall pipe, when measured in accordance with Test Method D2122.6.2.2 Inside DiameterThe tolerance on the nominal inside diameter shall be 62.0 %, when measu
