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 where 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 where 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-The values stated in inch-pound units are to be regarded as the standard. Note 2-See Appendix X1 for rationale used to develop this specification.
