1.1 This specification covers requirements and test methods for oriented polyethylene (PE) reinforced thermoplastic pipe (RTP) for transport of pressurized liquids and gases. The RTP pipe is outside-diameter controlled and is made in pipe sizes ranging from nominal pipe size (NPS) 2 to 6. This RTP pipe consists of three bonded layers. The inner layer is a homogeneously extruded PE tubular shape that provides support for the middle layer. The middle layer consists of two helical wraps of oriented PE tape that are applied onto the inner layer. The outer layer is a homogeneous coextruded layer of PE that is applied over the middle layer. 1.2 Units-The values stated in inch-pound units are to be regarded as the 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 The RTP-oriented PE pipe described in this specification is covered by two U.S. patents (US 7,093,620 B2 and US 2005/0158497 A1). Interested parties are invited to submit information regarding the identification of an alternative(s) to this patented item to the ASTM International Headquarters. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use.
This product is used in Europe and is being introduced in North America. The product needs to be manufactured in accordance with a North American standard. The primary users will be oil and gas companies.
