Oil pipe is a pipe that transports crude oil and natural gas from the oil and gas layer to the surface after drilling. It is used to withstand the pressure generated during the mining process and is used as a pipe for producing or injecting fluids. It adopts hot rolling or cold forming production process and is mainly used in the oil industry.

Casing introduction
Casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the entire oil well during the drilling process and after completion. Each well uses several layers of casing according to different drilling depths and geological conditions. The steel grades include J55, K55, N80, L80, P110, etc. It adopts hot rolling forming production process and is mainly used in the oil industry.
