Boiler Tube
Boiler Tube belongs to seamless steel tube, which shares the same production technique –hot rolled or cold drawn. It can be both of carbon steel and alloy steel .
There are low &medium pressure boiler tube and high pressure boiler tube as per the temperature of the applied conditions.
Boiler tube is always used in manufacturing heat-pipelines, containers, coal-saving devices, reheaters etc.
