Product Description

 

 

API SPEG 5CT
OCTG
 Casing and Tubing Pup Joints and Couplings
 

Our company is a modern enterprise mainly engaged in processing and selling seamless steel pipe products, and supplemented by the production and sales of thread protectors, coupling and pup joint. Our company's main products are seamless linepipe, seamless OCTG pipe and drilling pipe, sucker rod and seamless boiler pipe etc.

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.
