The boiler pipes made according to TU 14-3p-55-2001 (a pipe of high pressure) intend for boilers and pipelines of installations with high and supercritical parameters of steam.
On manufacturing techniques of a pipe happen:
Holodnodeformirovannye. A way of production – cold rolling of pipe preparation.
Hot-rolled. At production preparation heats up to temperature above a recrystallization limit.
The pipe boiler 12kh1mf, made of the alloyed steel, is applied when laying steam lines, in installations of high pressure. Pipes are capable to be exposed to long loadings at high temperature of the heat carrier and the environment.
Such conditions of a pipe are capable to sustain boiler rooms of this brand thanks to the content of chrome which gives the hardness and resistance to corrosion (12kh it (is lame) 1mf); to the molybdenum giving durability, resistance to corrosion at high temperatures (12kh1m (molybdenum) f); to vanadium which increases durability and density (12kh1mf (vanadium).
Pipes boiler can be bought various diameters, depending on a way of production.
Holodnodeformirovanny pipes from steel 12kh1mf make with a diameter up to 70 mm inclusive. Hot-rolled pipes are made by from 25 to 465 mm on outer diameter of steel 12kh1mf.
The boiler pipes made on TU14-3r-55-2001 are most demanded in power, gas – and oil-processing industry. The nuclear power, owing to increased requirements to safety, is one of main customers of this production. All boiler pipes pass several steps of control and have exclusive marking of manufacturer.
