All of the casing and tubing couplings and pup joints are with materials of steel grade including J55, K55, N80, N80-1, N80-Q, L80, P110, and so on. The casing couplings and pup joints have STC/LTC/BTC, and the tubing couplings have NUE/EUE. 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. All of our couplings meet the API 5CT.
