【国外标准】 Standard Specification for Field-assembled Anodeless Riser Kits for Use on Outside Diameter Controlled Polyethylene and Polyamide-11 (PA11) Gas Distribution Pipe and Tubing

This specification covers the qualification requirements and test methods for field-assembled anodeless riser kits for use with outside diameter controlled polyethylene gas distribution pipes and tubing in sizes of up to 2 IPS. The anodeless riser kits shall be manufactured in accordance with the specified materials, physical properties, and design, which include the riser casings, moisture seals, threads, bend radius, coatings, welding procedures, and riser adapter to riser casing connections. The riser adapter to riser casing connections shall tested by tensile pull testing.1.1 This specification covers requirements and test methods for field-assembled anodeless riser kits for use with outside diameter controlled polyethylene and PA11 gas distribution pipe and tubing in sizes through 2 IPS as specified in Specification D2513 polyethylene and Specification F2945 for PA11.1.2 The test methods described are not intended to be routine quality control tests.1.3 This specification covers the types of field-assembled anodeless riser kits described in 3.3.2.1.4 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 not considered standard.1.5 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures), shall not be considered as requirements of the standard.1.6 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.1.7 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.
