API 5CT coupling

Coupling is a short piece of tubing or casing to join tubing or casing together, couplings can be available in tubing coupling and casing coupling, material of couplings can be J55, K55, L80, N80 and P110. Tubing coupling ends can be EUE or NUE, threads of tubing coupling or casing coupling can be short thread, long thread or BTC thread. Tubing couplings can range size from 2⅜" to 4½", while casing couplings can range size from 4½" to 20".

 

Tubing coupling

Tubing coupling is used to join tubings together to complete an installation quickly, and tubing coupling allows a user to adjust length of tubings to meet field service. Tubing coupling features attachable and detachable, such can ensure tubing can be moved or disconnected for other purpose.
