High Pressure Boiler Hot Rolled Steel Pipe , Hot Rolled Tube 46''
Large Caliber
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 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.
