TORICH K55 N80 API 5CT L80 Oil Casing Carbon Seamless Steel Tube Pipe
Grade: H40, J55,K55, N80, L80, C90,T95, P110, Q125, V150
Function: Steel pipes used to support oil and gas well walls.
Application: Petroleum casing is a large-diameter pipe that serves to fix oil and natural gas well walls or boreholes. The casing is inserted into the borehole and fixed with cement to help the borehole separate the rock formations and prevent the borehole from collapsing, while ensuring the circulation of drilling mud to facilitate drilling and exploitation.
Length: R-1:4.88~7.62m,R-2:7.62~10.36m,R-3:10.36m to more.
