Seamless Carbon Steel Oil Casing Pipe

API5CT American standard oil casing and national standard oil casing advantages and disadvantagesCarbon steel seamless tube specification 



The oil pipe is mainly used for drilling oil and gas Wells and oil and gas transportation, including oil drill pipe, oil casing and pumping pipe. The oil drill pipe is mainly used to connect drill collar and drill bit and transfer drilling power.Oil casing is mainly used to support the borehole wall during drilling and after completion to ensure the drilling process and the normal operation of the whole well after 


completion.The pumping pipe mainly carries oil and gas from the bottom of the well to the surface.The oil casing is the lifeline that keeps the well running.Due to different geological conditions, the downhole stress state is complex, and the comprehensive action of tensile, compressive, bending and torsional stresses on the pipe body, which puts forward higher requirements for the quality of the casing itself.If the casing itself is damaged for some reason, it can reduce production or even kill the entire well.The 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 and so on.The steel grade used varies with well condition and depth.The casing itself is also required to have corrosion resistance under corrosive conditions.


The casing is also required to have crushing resistance in the place of complicated geological conditions.Oil casing is a kind of large-diameter pipe, which plays the role of fixing oil and gas well wall or well hole.The casing is inserted into the hole and fixed with cement to prevent the hole from collapsing and to ensure the circulation of drilling mud for drilling and production.Steel grades for oil casing: H40, J55, K55, N80, L80, C90, T95, P110, Q125, V150, etc.


Casing end machining form: short round thread, long round thread, trapezoidal thread, special thread, etc., used for oil well drilling is mainly used in the drilling process and to support the shaft wall after completion to ensure the drilling process and the normal operation of the whole well after completion.
