1.1 This specification covers requirements and test methods for the characterization of polyamide 66 pipe, tubing, and fittings for use in oil and gas applications. Pipe sizes in this specification range from to 8 NPS (IPS) and from to 1-1/4 NTS (CTS). The pipe and fittings covered by this specification, also known as line pipe, are intended for use in gathering of methane gas, oil, water, and other gases and fluids in the gas-gathering industry. 1.1.1 This specification does not cover threaded pipe. Generic fusion guidelines are given in Appendix X1. Design considerations are discussed in Appendix X2. In-plant quality control programs are specified in Annex A1. 1.2 The text of this specification references notes, footnotes, and appendixes that 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 the standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.4 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. NOTE 1-Pipe and fittings using heat fusion joining techniques produced from compounds meeting the requirements of Group 1, Class 8, and Grade 1 (PA181 or PA66) are intended for use with pipe and fittings manufactured from compounds meeting the requirements of Group 1, Class 8, and Grade 1. As per the recommendations of the respective resin manufacturers, no cross fusion between PA 181 (PA66), PA 323 (PA11), and PA 423 (PA12) compounds is permitted.
