We manufactures and supplies 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 sulphur and phosphor contents providing high tensile, ductility and corrosion resistance properties of pipes to be operated at low temperatures in various corrosion media.

Automatic ultrasonic and electromagnetic nondestructive inspection is performed to detect pipe outside and inside flows. Inspection of pipe ends before threading and couplings after treading is realized by magnetic-fluoroscopic flaw detection. 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.

Pipes are heat-treated in a computerized walking beam furnace. Steel grades and heat treatment regimes applied allow high-strength pipe to be obtained.

Threading of pipes and couplings is perfomed 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.
