STEAM AND HOT WATER PIPE AND PIPE FITTINGS:

Pipe and pipe fittings of  I-IV category steam and hot-water pipelines according to Federal norms and rules in the field of industrial safety “Industrial safety rules for hazardous production facilities that use equipment operating under excessive pressure” and Standards for thermal power plant steam and nuclear power plant pipelines elements according to Codes and standards for nuclear-power engineering NP-089-15, ASME, EN, OST 108.030.123-85, OST 10.030.124-85.For pipelines transporting steam with the temperature to 545°C and under the pressure of 255 kg/cm2 are used steel types 20, 15GS, 16GS, steel 12H1MF, 15H1M1F, 08N18N10T etc. and for pipelines with heightened parameters of working medium (temperature to 650°C, pressure 350 kg/sm2) are used high-temperature materials such as P-91, P-92 (Germany, the USA), 10H9MFB (Russia). Wall thickness of raw material reaches 80 mm, external diameters reach 1000mm, designed speed of working medium inside the pipeline is 40-60 m/sec.
