The API external-upset-end (EUE) tubing connection is widely used
because it is 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 API SPEC 5CTSR13)
Designed in accordance with API 5CT/5B and are made of good
seamless steel. EUE petroleum tubing coupling cover the outer
diameter from 77.80mm to 141.30mm, it is bigger than the outer
diameter of the non upset threaded end product.
