Please note: because the price of raw materials has been floating recently, so we just marking a symbolic price on the web. If you are interested in our products, please directly contact us by WhatsApp or TrademanagerAPI 11b Class T Sucker Rod Coupling
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. Our products have already passed the identification of the Quality Testing and Inspection Centre of Oil Pipe of CNPC (China National Petroleum Corporation).
