Couplings of Casing
We manufacture all range of couplings as per API specifications in all groups for casings and tubing. All of our couplings meet the American Petroleum Institute (API) Specifications 5CT. The coupling are subjected to be phosphated to prevent rusting and coated on thread by VCI oil. The range of couplings extends from 1.9” to 20”, under grades H-40, J-55, K-55, L-80, N-80, C90, T95, P-110, Q125 etc. We also provides all kinds of accessories of casing and tubing, like pup joints, nipples, cross overs , drift gauges etc.
