Product Description

Specification

Oil casing is a steel pipe used to support the wall of oil and gas wells to ensure the normal operation of the entire oil well after drilling and completion. Several layers of casing are used for each well according to different drilling depths and geological conditions. Cement cementing should be used after the casing is run down the well. It is different from tubing and drill pipe and cannot be reused. It is a one-time consumable material. Therefore, the consumption of casing accounts for more than 70% of all oil well pipes.
Casing can be divided into: conduit, surface casing, technical casing and oil casing according to the usage.
API 5CT oil tubing 
1) API Spec 5CT. 
2) J55, K55, N80, L80, P110
