Standard Specification for Polyethylene (PE) Gas Pressure Pipe, Tubing, and Fittings
This specification covers the requirements and test methods for material, dimensions, hydrostatic burst strength, tensile strength, chemical resistance, sustained pressure, heat fusion, and impact resistance of plastic pipes, tubing, and fittings used for direct burial and reliner applications in fuel gas mains and services for the distribution of natural gas. This specification does not cover threaded pipe. The plastic used to make the pipes and fittings shall be virgin plastic or reworked plastic having Plastics Pipe Institute (PPI) long-term hydrostatic design stress and hydrostatic design basis rating.
1.1 This specification covers requirements and test methods for material dimensions and tolerances, hydrostatic burst strength, chemical resistance, and rapid crack resistance of polyethylene pipe, tubing, and fittings for use in fuel gas pipelines for direct burial and reliner applications. The pipe and fittings covered by this specification are intended for use in the transmission and distribution of natural gas. Requirements for the qualifying of polyethylene systems for use with liquefied petroleum gas are also covered.
1.1.1 This specification does not cover threaded pipe. Design considerations are discussed in Appendix X1. In-plant quality control programs are specified in Annex A1 and Annex A2.
1.1.2 See Specification F2619/F2619M for polyethylene piping for pressure or non-pressure oil and gas producing applications to convey fluids such as oil, dry or wet gas, multiphase fluids, and non-potable oilfield water.
1.2 The text of this specification references notes, footnotes, and appendixes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.
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 The following is an index of the annexes and appendix in this specification:
In-Plant Quality Control for all materials up to 12 in.
In-Plant Quality Control for PE materials 14 in. and larger.
1.5 The following precautionary caveat pertains only to the test method portion, Section 6, of this specification. 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.
1.6 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.
