Some tubing couplings are designed to be attached and detached repeatedly, allowing tubing to be moved, or disconnected for different accessories to be added.
Some specifications of the API 5CT tubing coupling:
1)API 5CT Tubing coupling
2)Size: 1.9''-4 1/2''
3)Thread Type: NUE, EUE
4)Grade: J55,K55,N80,L80,P110
API 5CT Casing Coupling
The API 5CT casing couplings are short pieces of casing used to connect the individual joints. The couplings are normally made of the same grade of steel as the casing.
The casing coupling refers to casing is mainly used to be a connection that joins two sections of pipe together.
