Casing Coupling

Couplings are used to hold the neighboring joints together during axial tension or compression.The common oilfield API-5CT casing couplings include J55, K55, N80 and P110 in accordance with API 5CT/5B, can be classified as STC (short thread), LTC (long thread) BTC (buttress thread) and premium connections.

We cover a size from 4-1/2″ to 20″,STC, LTC and BTC, we also manufacture premium connections based on our customer enquiry.

BTC Casing Coupling

 

We provide LTC casing coulings from 4-1/2″ to 20″, in grade J55, K55, N80, L80 and P110.

Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For all casing sizes, the threads are not intended to be leak resistant when made up.

The round-thread (STC or LTC) casing-joint strength is given as the lesser of the fracture strength of the pin and the jump-out strength.
