Can internal threaded pipes with the same size but different wall thicknesses be connected to external threads of the same size?
Thread Content
ASME B1.20.1 specifies parameters such as the thread depth and pitch, which are not related to the outer diameter of the pipe. Is it possible that a particularly thick 3/4” male-threaded pipe and a thinner 3/4” male-threaded pipe cannot be screwed into a 3/4” female-threaded pipe, or that only a small portion of them can be inserted? After all, the outer diameter of pipes of the same size is identical. I would appreciate advice from those with experience in this area; thank you.
3/4” refers to the diameter of the threaded part of the pipe, and does not represent anything else. For example, if a threaded hole on a device is φ10mm, it is compatible with screws of size 10. For reference.
Fittings are generally used to connect threaded pipes; I’ve never seen pipes have internal threads fabricated directly on them； It is processed into a tapered thread, becoming tighter as it is tightened more.
