ABSTRACT:
A threaded tubular connection is depicted (120) for connecting joints of reinforced thermosetting resin pipe. Box threads are formed in both ends the joints as at (107) for connection by means of a coupling (102) formed with pin threads (104) on both ends. The coupling is formed of a material having a more reliable compressive strength than the pipe material, to prevent cracking and shattering of the pipe material upon make-up. A process for forming threads with the pipe joints is disclosed.
