Product Description

Casing coupling is a tool in oil field, mainly used for casing connection. The casing coupling mainly solves the problem that the existing coupling is prone to fatigue fracture due to stress concentration.

Connection structure: the end is connected with the inner wall of the collar by a cone thread, and the end of the collar body is connected with the oil pipe by the same thread and flat thread with the pitch.

The utility model has the advantages of eliminating the stress concentration at the root of the external thread of the single cone thread connecting sleeve, and is not easy to produce fatigue fracture, and the connection effect is good.

The main types of casing joint threads are: long round thread casing joint (LC), short round thread casing joint (SC), buttonwall thread casing joint (BC), steel numbers are mainly: J55, K55, N80, L80, P110 and so on.
