Fine grain steel pipes for pressure purposes are used in power engineering and in associated fields of industry. They are used as pipes in elevated pressure installations as well as in installation where it is important to guarantee the appropriate resilience of steel in varying 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 to 12,5 mm in the case of cold drawing. The pipes are manufactured with TC1 tests (I requirement level) and with TC2 tests (III requirement level).
