Abstract

This specification covers coiled, machine-made glass fiber reinforced thermoplastic pipe up to 6 in. nominal size, having discrete, unbonded inner and outer layers of thermoplastic compounds and an intermediate structural layer of unbonded, dry glass fiber reinforcement to provide higher strength. Included are a classification system and requirements for materials, mechanical properties, dimensions, performance, methods of test, and marking. Reinforced thermoplastic pipes are used for oil and gas applications, including transport of multiphase fluids, hydrocarbon gases, hydrocarbon liquids and non-potable water. Physical requirements cover workmanship, dimensions and tolerances, pipe requirements (pressure design basis, cell classification, pipe re-categorization, bending requirements), fittings requirements, joint requirements (leak test, tensile pull test requirements, temperature cycling, elevated temperature test).

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers coiled, machine-made glass fiber reinforced thermoplastic pipe up to 6 in. nominal size, having discrete, unbonded inner and outer layers of thermoplastic compounds and an intermediate structural layer of unbonded, dry glass fiber reinforcement to provide higher strength. Included are a classification system and requirements for materials, mechanical properties, dimensions, performance, methods of test, and marking. Reinforced thermoplastic pipes are used for oil and gas applications, including transport of multiphase fluids, hydrocarbon gases, hydrocarbon liquids and non-potable water.

1.2 The piping system will comprise one or more runs of pipe along with mechanical fittings, designed and for use with this composite pipe, connecting them to each other and to the other pipeline components.

1.3 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.

1.4 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.
