Company Brief

Oil Steel Tube (Thailand) Co., Ltd. founded in July 2011, presently has three lines of producing Oil well pipes and casing .It mainly processes oil well pipes , coupling and pup-joint in all size and several grades with outside diameter from Φ60.3~Φ339.7mm. Annual capacity is up to 80,000 tons . The company carries out management according to ISO9001:2000 and API Q1 standards. The strength of several experienced specific technologists provides our products with powerful technology support.

Oil well pipes made by OST are mostly used in the process of oil field development for the task purposes of oil extraction, fracturing, acidification, affuse, gas injection and well workover. The body stocks of oil well pipe of OST adopt the technologies of electric steel making, vacuum degassing, secondary steel making processes, which make products with equal component and good metallurgy quality. Roller trio skew rolling and 12- frame tension reducing technology can guarantee the good shape, high precision dimension and nice mechanical properties; finishing and nondestructive technology (ultrasonic and eddy current testing) can assure the excellent exterior and interior quality; moreover, the parameter of screw thread made by high precision numerical control lathe is 30% stricter than API standard, which leaves the properties of anti-thread gluing, anti-slipping and sealability up to set values of API standard.
