Anotace textu normy ASTM F2905/F2905M-22 :

This specification covers the requirements and test methods for outside diameter controlled, pressure rated, black metric-sized and IPS-sized crosslinked polyethylene (PEX) pipe, fittings and joints intended for oil and gas producing applications. It presents the criteria for materials made in pipe dimension ratios ranging from 6 to 17, along with workmanship, burst pressure, hydrostatic sustained pressure, bent-pipe hydrostatic pressure, stabilizer functionality, degree of crosslinking, and chemical resistance. It also includes guidelines for pipe and fittings markings.

1. Scope

1.1?This specification covers outside diameter controlled, pressure rated, metric-sized and inch-sized black or yellow crosslinked polyethylene (PEX) pipe made in pipe dimension ratios ranging from 6 to 17. Included are requirements and test methods for material, workmanship, dimensions, burst pressure, hydrostatic sustained pressure, stabilizer functionality, bent-pipe hydrostatic pressure, degree of crosslinking, chemical resistance, and minimum operating temperature. Requirements for pipe markings are also given. The pipe covered by this specification is intended for pressure or non-pressure oil and gas producing applications, such as conveying oil, dry or wet gas, gas gathering, multiphase fluids, and non-potable oilfield water. This specification does not cover piping for gas distribution applications.

1.2?This specification also includes requirements for joints made between PEX pipe and polyethylene electrofusion fittings (specified in Specifications F1055 or F3373). Fittings to be used with PEX pipe manufactured to this Specification are in Specification F2829/F2829M. Installation considerations are in Appendix X3.

1.3?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.

1.4?UnitsThe values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

Note 1:?Metric sized (SI units) pipe should only be joined with corresponding metric sized fittings, and inch sized pipe should only be joined with corresponding inch sized fittings. Inch sized fittings should not be used for metric sized pipe, and metric sized fittings should not be used for IPS inch sized pipe.

1.5?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.
