API 5CT L80 casing tube

Grade: L80-1, L80-9Cr, L80-13Cr
Standard: API 5CT
Length: R-1:4.88~7.62m;
               R-3:more than 10.36m;

L80 well casing is placed down-hole to offer structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must hold own deadweight and withstand the torque and transaxial pressure placed on it while running down-hole.
