API 5CT TUBING CASING COUPLING
Casing and Tubing are produced in accordance with API specifications. The heat-treatment lines are completed with advanced equipments and detecting instruments that can handle casing in 5 1/2" to 13 3/8" (φ114~φ340mm) diameters and tubing in 2 3/8" to 4 1/2" (φ60~φ114mm) diameters. The annual heat-treatment capacity is about 150 thousand tons. The thread machining line can handle all API grade tubings, casings, couplings and screen pipes in 2 3/8" to 20" (φ60~508mm) diameters and with annual capacity of 300 thousand tons.
