Thread type in a Threadolet
Thread type in a Threadolet
(OP)
Here's a total newbie question for you.
For Bonney Forge Threadolets they state the outlet size as a size in inches. But there is no clue as to what thread type it is. I can only conclude that its somehow assumed that the reader already knows. My problem, I don't know and there are a lot of threads to choose from, NPSC, NPSF, NPSI, NPSM, ANPT, NPT, NPTF, PTF etc. etc.
So, what is it that I am supposed to know in this case?

"Threaded ends are in accordance with ANSI/ASME B1.20.1
Design per MSS-SP-97"
RE: Thread type in a Threadolet
That then limits my possible candidates to NPSC, NPSM and NPT. While I think we can rule out NPSM as it is for mechanical use I still don't know if it is a straight or taper thread.
PS I haven't got access to B1.20.1 or MSS SP-97.
RE: Thread type in a Threadolet
Have you called your threadolet supplier to ask how you specify the thread type you need? Do you need the NPT type?

Thanks for your replies.
RE: Thread type in a Threadolet
Virtually every US project is NPT
Do you have a pipe specification for the rest of the piping systems ?
RE: Thread type in a Threadolet
I am setting up new internal component standards for ASME pipe fittings and adding our own article numbers and design directions. To simplify for the designers I would like to add this type of information from the outset rather than having the designers figuring this out for them selves each time.
RE: Thread type in a Threadolet
Then You need threadolets with BSP thread.
