Description
Coupling is an API threaded tubular section of steel pipe used in connecting two pipe joints together. Structurally, they are short lengths of heavy wall pipe with similar type of box threads on each end.Tubing coupling is a type of drilling tool used in oil field. It is mainly used for connecting oil pipes. This pipe coupling has solved the problem that the existing couplings tend to crack due to stress concentration. The oil pipe ends and the inner wall of the steel coupling are connected through threads. The ends of the coupling and the oil pipe have the same type of threads. This type of connection is not easy to crack and the connection effect is good. The tubing coupling can effectively avoid the oil well string dropout accident.
