All our products are produced and processed according to , with the materials of steel grade including J55, K55, N80, N80-1, N80-Q, L80, P110 and so on. The couplings have three types, namely STC LTC and BTC. 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, profile and so on.
