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.

 

To improve the seal performance of API EUE tubing in high-pressure service, a grooved coupling, which accepts nonmetallic seal rings, is sometimes used in the coupling (see APISpec. 5CT SR 13).

 

Designed in accordance with API 5CT/5B and are made of good seamless steel. EUE petroleumtubing coupling cover the outer diameter from 77.80mm to 141.30mm, that is bigger than the outer diameter of the non upset threaded end product.
