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.
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. API NUE joints are available in sizes of 1.050 to 4.500 in.
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.
On ground inventories are available from our Houston Inventory warehouse. API couplings are know for it's high efficiency and long service life.
