Fine grain steel tubes for pressure purposes are used in power engineering and other associated fields of industry. They are used as pipes in elevated pressure installations and everywhere where it is necessary to assure the appropriate level of impact resistance of steel in different temperatures.

The pipes are manufactured with the diameters between 21,3 – 660 mm and with the wall thickness of up to 100 mm in the case of hot rolling, and with the diameters between 10,2 – 108 and with the wall thickness of up to12,5 mm in the case of cold drawing. The pipes are manufactured with TC1 tests (I requirement level) and TC2 (III requirement level). The pipes are manufactured for use in standard, elevated, and low temperatures as well as for special applications in low temperatures.
