API 5CT L80

API 5CT L80 casing tube is widely applied in petroleum, construction, shipbuilding, smelting, aviation, electric power, food, paper, chemical industry, medical equipment, heat exchangers etc.


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.
