Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers requirements and test methodsfor materials, dimensions, workmans
3、hip, and markings foron-site manufactured multilayer reinforced polyethylene com-posite pipe. It covers nominal sizes 6 in. through 36 in. (150mm through 915 mm). These multilayered reinforced polyeth-ylene composite pipe products2are assembled and installed invarious lengths, including long continu
4、ous lengths. Theseproducts are intended for the transport of crude oil, natural gasand hazardous liquids in the rehabilitation of existing pipelinesand for new pipelines.NOTE 1Hazardous liquids are those liquids defined by the U.S.Department of Transportation in 49 CFR 195.2.1.2 The values stated in
5、 inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.3 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It
6、is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

23、ussionThe typical reinforced polyethylenecomposite pipe to be described in this standard is a multilayerpipe construction consisting of a polyethylene liner or corepipe, co-helically wrapped with multiple layers (counterwound in pairs) (of non-metallic reinforcing material, and thenwrapped with an o
24、uter polyethylene or other thermoplasticprotective layer. The polyethylene core pipe is heat fusionjoined to make long continuous lengths of pipe. Longitudinaldirection reinforcing materials may be applied to reinforce thepipe linearly to increase the strength in sliplining installations.The polyeth
25、ylene liner pipe may either be manufactured on-siteor shipped to the site and fusion joined on-site prior to beingwrapped with the reinforcing materials. These products areconstructed from individual pipe lengths of the polyethylenecore pipe and not from coiled polyethylene pipe. See Fig. 1.3.5 on-s
