: Carbon steel seamless pipes for use in low and medium pressure boilers, petroleum casing tubes, ships, fluid conveyance, petroleum cracking, chemical fertilizer equipments, structures, and hollow pumping rods. We can produce seamless steel pipes from 12″ to D40″, thickness SCH30, SCH40, SCH80, SCH160 and so on, according to the standards such as \ASTM\API 5L\BS EN ISO, 

(1)From 2″-4″, our pipes are cold drawning.

(2)From 4″-12″, our pipes are hot rolling.(stok available )

(3)Over 12″, our pipes are hot expending max 40'
