Casing
Casing is a series of steel pipes that are set inside the drilled wells to stabilize well or boreholes. Every well is equipped with different casing according to drilling depth and geological condition. Our casings meet API Spec 5CT, API Spec 5B, PSL1, PSL2 and PSL3 standards. The bore diameter of customized products is between114.30 and 339.72mm.
