  • API EUE Tubing Couplings - API Coupling, Casing Pipe

    API EUE Tubing Couplings The API external-upset-end ( EUE ) tubing connection is widely used because it is a good, serviceable connection in most wells. The EUE joint has a designed joint strength in tension and pressure strength greater than that of the pipe body and, therefore, is considered a 100% joint efficient connection.

  • Anyone know about API (oilfield) threads?

    The notation that points to the thread says "1.315 x 10NU". The part itself is called a collar, and connects long pieces of pipe that go down into the ground. (At least these people call it a collar. I've also come across the terms pin and box, but I don't know if these are just oilfield terms for the male pipe and female coupling.)
