The casing pipe is applied in petroleum & gas exploration.It is the important part of oil drilling, it is the lifeline of oil well. According to the different geological conditions, the stress state is complicated, so the quality of the casing pipe has paramount importance.
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or well bore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Oil casing pipes are the lifeline which keep oil wells running. API 5CT Casing is a large-diameter pipe, it serves as the structural retainer for the walls of oil and gas wells, or well bore. It has widely use in the oil industry.
Casing is the major structural component of a well. Casing is needed to: 1）Maintain borehole stability 2) Prevent contamination of water sands 3) Isolate water from producing formations 4) Control well pressures during drilling, production, and workover operations Casing provides locations for the [...]
Casing pipe is most often used in underground construction projects to encase or protect utility lines from being damaged.
API-5CT N80 oilfield casing pipe contains N80-1 and N80-Q types. Those two materials are absolutely consistent regarding the chemical composition and mechanical attributes, they are just various in the heat treatment.
API 5CT L80 oil casing pipe is a kind of large diameter pipes used for the drilling. API 5CT L80 oil casing pipe diameter we offer ranges from 4.5 inch to 16 inch. API 5CT L80 oil tubing pipe diameter ranges from 1.05 inch to 4.5 inch.
The P110 API-5CT steel casing pipe is the high grade amongst other grades of steel. White band is marked on the finished casing to point out the materials. During petroleum drilling and producing, this casing pipe is generally used in a variety of complicated territory due to its higher tensile strength and higher yield.
API 5CT Q125 Casing serves to transport both crude oil and natural gas from oil and gas layer to the surface pipeline after drilling is completed. It is able to bear the pressure produced by the exploitation process.
The casing named L80-9Cr casing pipe manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. Used in wells with carbon dioxide environments.
