Oil well pipe
Casing, tubing, drill pipe, kelly, and drill collar are collectively referred to as oil well pipe. Casing is a steel pipe that supports the wall of an oil and gas well. It is mainly divided into surface casing, technical casing and oil layer casing; tubing is set in the oil layer casing after the oil and gas well is cemented to allow oil and gas to flow to the ground from there. The special seamless pipe; the oil well pipe produced by our company is mainly oil pipe and casing.
