Product Description

 

Tubing Couplings

We carry size range of 2-3/8", 2-7/8″, 3-1/2″,4″ and 4-1/2″ in J55, K55, N80, P110 grade. All of our couplings meet the API Specifications 5CT/5B.
Couplings are short lengths of pipe used to connect 2 joints of tubing or casing. They come with painted colour codes on their external surface to indicate their grades.
API EUE Tubing Couplings
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, that is bigger than the outer diameter of the non upset threaded end product. 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.


API NUE Tubing Couplings
Designed in accordance with API 5CT/5B and are made of good seamless steel. NUE tubing coupling possesses the outer diameter range from 73.02 to 132.08mm. API nonupset (NUE) tubing is used much less than EUE tubing. The cost of NUE is only slightly less than EUE, and the joint strength is substantially less. The coupling joint diameter of NUE is less than EUE, which offers some advantages when clearance is small.
