Oil Casing Pipes

Our Oil Casing Pipes are available in various wall thicknesses and diameters. We are among the leading manufacturers and suppliers of Oil Casing Pipes in China, which are popular among customers in many countries of the world.

Oil Casing Pipes are pipes used for the transportation of crude oil and natural gas from an oil or gas layer to the surface after drilling is complete. It is made to withstand the pressure generated from the extraction process. Oil casing pipes are manufactured in the same way as casing, except that an additional process known as "upsetting" is applied to thicken the pipes.
