Product Description

Boiler tubes are used in heat exchange appliances in which the energy is transferred from one medium to the other. The pipes are manufactured from carbon and low-alloy steel grades which are resistant to loads under high pressure and temperatures. They are used for the construction of power engineering appliances such as: boilers, heating coils, stoves, heaters, heat exchangers.
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,

Size: OD 10,2 - 108mm  and with the wall thickness of up to 12,5 mm in the case of cold drawing. 

 
Grades: St 35.8, St 45.8, 15Mo3, 13CrMo44, 10CrMo910, 14MoV63
