Boiler pipes which are applied in coppers and pipelines. They are made from the carbonaceous or alloyed steel of qualitative brands (m/s 15H1M1F). For smelting electric or martin furnaces are used, processing them synthetic slag. Pipes undergo ultrasonic testing, and also mechanical tests that gives high degree of reliability. At mechanical influence, the pipe is flattened, stretched, checked for the hardness, impact strength, distribution, etc. Also are checked on chemical indicators. This product maintains temperature more than 500C, and is capable to keep the working condition at 98 and more than a MPa. For the hot-rolled pipe TU14-3-460, diameter makes the 57-219th, for a pipe of the same brand, but only cold deformation-10-76mm. Thickness walls-3,5-40mm and 2-12 respectively for pipes of cold deformation. Insignificant deviations in diametre:1% towards increase or reduction for pipes of hot deformation, a wall limit, in the diameter up to 108 mm can be, will make +15,-10%. At production of this type of pipes, use such brands stali:15kh1m1f; 12H1MF; 15XM; 15GS; 20PV; 20.
