E-mail:sales@highboomingpipe.comCouplings are used to hold the neighboring joints together during axial tension or compression. As we know steel pipe coupling is a short pipe or tube that with threads on both ends, used to connect pipelines. So It is a kind of pipe fittings that with threaded connection, the advantage is easy for pipeline maintenance or to replace the broken pipe.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.
To be simple, it is the internally threaded cylinder for joining two lengths of threaded pipe.With this purpose, API 5CT standard coupling plays an important feature in connecting casing and tubing line pipes. On the contrary, the biggest different with general steel pipe coupling is: API coupling manufacturing processes is more rigorous, requires a precisely control in the different processes as blew listed.
Raw material selection
Mechanical test including tensile strength
Impact test
Chemical properties control
Sulfide stress cracking test (for Material grades in C90 or T95)
Size tolerances, OD, Wall Thickness, Length and Straightness
Threads control, threads quantity per inch, threads angle etc (Premium threads option will be more rigorous)
Heat treatment
Additional markings
Material certification
Product Specification Level (PSL-2 or PSL-3)
