Product Description

20 Years Supplier API Nu Eu Pup Joint with Coupling for OCTG

Product Description

 

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.
