工程常见问题
The table lists end-to-end length M per ASME B16.9 for standard weld caps matching SCH 40 wall on the listed NPS.
Weld caps close the pipe end for testing when welded in place. For repeated bolt-up tests, a blind flange may be more suitable.
Special caps from approved drawings can be quoted. Standard catalog caps follow B16.9 straight caps.
Yes on inquiry. Wall thickness and weight differ from SCH 40; specify schedule on the MTO.
