API 5CT L80 Casing Tubing can be widely applicable to petroleum, construction, shipbuilding, smelting, aviation, electric power, food, paper, chemical industry, medical equipment, boilers, heat exchangers, metallurgy and so on.


L80 Casing is placed downhole to provide structural integrity to the wellbore and must withstand external-collapse pressure from rock formations and internal-yield pressure from fluid and gas. It must also hold its own deadweight and withstand the torque and transaxial pressure placed on it while running downhole.
