The Processing program of steel casing pipe

Steel Casing pipes, which are used for casing of oil and gas. Casing pipes are manufactured of metal in-house produced and smelted in the electric furnace, treated with synthetic slags and cast by continuous casters. The applied steel making process ensures the achievement of chemically pure steel with reference to phosphor contents providing high tensile, ductility and corrosion resistance properties of pipes to be operated at low temperatures in various corrosion media.

Threading of pipes and couplings is performed by numerical control machine tool. The facilities allow the production of both standard (“Buttress”) and up-to-dated high-sealed threads of “Premium” type. Every threaded pipe end and every coupling is controlled with a thread gauge.

Rolling using a press piercing mill and continuous mill equipped with a fixed mandrel allows strict measurement tolerances to be obtained and ensures a lack of pipe body and surface flows. Wall thickness is inspected throughout the pipe length by the ultrasonic unit.
