API 5CT oil casing can be divided into different steel grades according to the strength of the steel itself, namely J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.The steel grade is different depending on well condition and depth.API 5CT P110 casing pipe is also required to have the anticorrosion function under the decay environment.
It is also required that API 5CT P110 casing pipe has the anti-extrusion function in the complex geological conditions.API 5CT P110 casing pipe is used to support the borehole wall of oil and gas Wells, to ensure that the drilling process is followed by the completion of the abnormal operation of all Wells. Depending on the depth and geology of each well, how many layers of casing are used.
API 5CT P110 casing pipe should be cementing after well under casing. Unlike tubing and drill pipe, it cannot be used repeatedly and belongs to one-time consumption data.Therefore, the consumption of API 5CT P110 casing pipe accounts for more than 70% of all well pipes. API 5CT P110 casing pipe can be divided into: conduit, surface casing, skilled casing and oil layer casing.
