Pipe Supports - MSS-SP-58, 69 and ASME B31.1, Section 130

Pipe Supports - MSS-SP-58, 69 and ASME B31.1, Section 130

Pipe Supports - MSS-SP-58, 69 and ASME B31.1, Section 130

(OP)
simple question:

are pipe supports for 10-inch, std wall, (water) allowed to have NPS pipe threads for adjustment purposes?  the pipe and/or coupling is turned to adjust for final elevation of saddle support.

picture this support, a threaded flange at base (concrete floor), a section of pipe (4<length<8 feet) with a coupling about 1-foot below below saddle support.  support pipe is 2-inch and each support has 3 threaded locations for adjustment.

as i read and understand these standards and the code (B31.1, Section 130), this configuration does not comply.

i have read another thread, thread378-182995: Trapeze Supports, which the last 2 postings are interesting.  mainly that there are several installations i am familiar with utilizing unistrut with a mss-sp-58/69 type support fastened to unistrut.

well, i just read par. 8 in mss-sp-58 where pipe threads are permitted.

responses are welcome, mainly clarification!

thanks!
