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.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
