Hi, does anyone know where i could get some specs on tool joint threads. I managed to get specs on tubing and casing threads 8rd. 10rd. Etc. But can't seem to find info on tool joint threads. Some of these are quite coarse. 5 TPI. and large joints as well is it wise to thread these in my manual lathe? Hope someone can help.
thanks for now.
You might try API (American Petroleum Institute). I believe they have supplier lists for their "approved" suppliers who can meet their standards.
