    API Coupling for Tubing and Casing Pipe - Permanent Steel

    The casing pipe coupling is a kind of oilfield drilling tool, which is mainly used for the connection of the oil pipe, and mainly solves the problem that the existing coupling easily generates fatigue fracture due to stress concentration. The tubing coupling structure is:the tubing end is connected to the inner wall of the coupling by a taper thread, and the end of the coupling body and the API Coupling for Tubing and Casing |tubing couplingoctg Revata Engineering offers a wide variety Couplings for Casing, Tubings and Line Pipes. The Tubing / Casing and Line Pipe Couplings are manufactured to meet the requirements of API 5CT and API 5L certifications respectively. Below are the sizes of the API 5CT Couplings for Casing

    Equipoutlet is a leading distributor of top quality API 5CT tubular products. Including API couplings, Casing pipe, tubing pipe and other oilfield service equipment. Located in Houston, Texas, EOI has been serving for 10 years. API Coupling,Coupling Stock - Seamless Carbon Steel Pipe The coupling stock is mainly applicable in the manufacture of pipe couplings. With a threaded cylinder, API coupling is used for connecting two thread pipes. Our company supplies tubing coupling and casing coupling. JST is able to produce J, N, L and other grades of flat or external upset tubing pup points with various specifications in accordance with API standards. API Couplings,Tubing and Casing Couplings,LC/SC/BC API Couplings are brief items of casing or tubing utilized as a sort of link in between the specific joints. They are usually made from the exact same quality of steel as the casing or tubing. As required by API 5CT standard, the couplings are always given color layer in order to differ the steel grade. J55-Green, N80-Red. P110-White. C75-Blue

    API coupling specification - API Coupling, Casing Pipe

    Normally tubing coupling OD maximum is 4 1/2, as the tubing pipe is applied for the drilling activities (Inside the tubing is the sucker rod to drill/pump the oil), couplings type is more various and rigorous than casing, mostly used is thicken type upset coupling (Internal upset and external upset), for short is EUE coupling, it is the most Casing & Tubing Coupling - Lake PetroCasing & Tubing Coupling.

OCTG Casing and Tubing Pipe Dimensions & Specificaitons Casing and Tubing coupling. As we know, the coupling of steel pipes is a pipe or short pipe with threads on both ends and is used to connect pipes. The API coupling plays an important role in the connection of pipes and casings, since it requires more rigorous manufacturing processes than normal steel couplings. The recommended standard is API 5B.
