ASTM F2896-11(2017)

Standard Specification for Reinforced Polyethylene Composite Pipe For The Transport Of Oil And Gas And Hazardous Liquids

SCOPE
1.1 This specification covers requirements and test methods for materials, dimensions, workmanship, and markings for on-site manufactured multilayer reinforced polyethylene composite pipe. It covers nominal sizes 6 in. through 36 in. (150 mm through 915 mm). These multilayered reinforced polyethylene composite pipe products2 are assembled and installed in various lengths, including long continuous lengths. These products are intended for the transport of crude oil, natural gas and hazardous liquids in the rehabilitation of existing pipelines and for new pipelines.
Note 1: Hazardous liquids are those liquids defined by the U.S. Department of Transportation in 49 CFR 195.2.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.2.2.1 Discussion—
The typical reinforced polyethylene composite pipe to be described in this standard is a multilayer pipe construction consisting of
a polyethylene liner or core pipe, co-helically wrapped with multiple layers (counter wound in pairs) (of non-metallic reinforcing
material, and then wrapped with an outer polyethylene or other thermoplastic protective layer. The polyethylene core pipe is heat
fusion joined to make long continuous lengths of pipe. Longitudinal direction reinforcing materials may be applied to reinforce
the pipe linearly to increase the strength in sliplining installations. The polyethylene liner pipe may either be manufactured on-site
or shipped to the site and fusion joined on-site prior to being wrapped with the reinforcing materials. These products are
constructed from individual pipe lengths of the polyethylene core pipe and not from coiled polyethylene pipe. See Fig. 1.
