Product Description

API 5CT
Tubing & Casing




All of the 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 ranges of 2-3/8", 2-7/8", 3-1/2", 4", and 4-1/2" in J55, K55, N80, and P110 grades. All of our couplings meet the API Specifications 5CT/5B.
