|Specification API 5CT Casing Long Thread Coupling:|
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.
