API 5CT Casings

Oil casing is a large-diameter pipe that serves to secure the walls or boreholes of oil and gas wells. A casing is inserted into a wellbore and fixed with cement to help separate rock formations and prevent wellbore collapse, while ensuring the circulation of drilling mud for easy drilling and mining.

Steel grades for oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc. Processing forms of casing end: short round thread, long round thread, trapezoidal thread, special buckle, etc. Used for oil well drilling, it is mainly used to support the wellbore during the drilling process and after completion, to ensure the normal operation of the entire oil well during the drilling process and after completion.
