Product Description

                                                         API 5CT 2 7/EUE  tubing coupling

 

Product Description

 Tubing coupling is a kind of oil field drilling tool, which is mainly used for tubing connection.The coupling mainly solves the problem of fatigue fracture caused by stress concentration.

The coupling is divided into tubing coupling and casing coupling.

 Feature

  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.
