Central heating Boiler Steel Pipe belongs to smooth steel tube, which shares the very same production discipline– hot rolled or cool drawn. It can be both of carbon steel with alloy steel.

There are low & average pressure central heating Boiler Steel Pipe and above ground stress Boiler Steel Pipe as per the temperature of the employed problems.
Boiler Steel Pipe is constantly made use of in manufacturing heat-pipelines, containers, coal-saving tools, reheaters and so on.
