Anotace textu normy ASTM F682-82a(2023) :
This specification covers wrought carbon steel sleeve type pipe couplings suitable for joining carbon steel pipes. Couplings are furnished in two types as follows: Type I couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of extra strong pipe. The couplings shall be manufactured from material having a chemical composition conforming to the requirements specified. Couplings made from plate or tubular products need not to be heat treated. Hot-formed couplings finished at a temperature in excess of a certain value shall subsequently be annealed, normalized, or normalized and tempered. Cold-formed couplings upon which the final forming operation is completed at a temperature below a certain quantity shall be normalized or shall be stress-relieved. Carbon steel couplings made from forgings shall subsequently be annealed, normalized, or normalized and tempered. Mechanical properties of steel such as tensile strength, yield strength, yield point, and elongation shall be determined.

1.1?This specification covers wrought carbon steel sleeve-type pipe couplings suitable for joining carbon steel pipes. 1.2?Type I couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II couplings are intended for use on all schedules of pipe in which the pipe wall thickness does not exceed the wall thickness of extra strong pipe. 1.3?This specification does not cover cast steel couplings. Note 1:?See Appendix X1
for rationale used to develop this specification.
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 are not considered standard. 1.5?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. |
