Product Description

Product Description

All of tubing couplings are with materials of steel grade including J55, K55, N80, N80-1,N80-Q,L80,P110 and so on . The casing couplings have two types, namely NU and EU. By numerically controlled lathe and import molding cutter, the processing of thread can be finished in one time,which ensures its commonality and interchangeability. We have complete testing abilities, adopting a whole set of single testing apparatus of thread, including tape,pitch,tooth depth and profile.

 

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.
