What is the main feature of 20G boiler tube?

20G high-pressure boiler tube (GB5310-2008) is a high-quality carbon structural steel for the manufacture of superheated steam pipes, boiling water pipes and superheated steam pipes, large smoke pipes, small smoke pipes and arch brick pipes for low-pressure boilers of various structures. Hot rolled and cold drawn (rolled) seamless steel tubes. 20G seamless steel pipe for structure use (GB/T8162-2008) is a seamless steel pipe for general structure and mechanical structure.

The corrosion resistance of 20g high-pressure boiler tubes is more than 30 times that of steel. 20g high pressure boiler tube has high corrosion resistance. And coated with bituminous paint to solve the problem of internal and external corrosion, gray cast iron pipes and steel pipes can not be solved. Therefore, the corrosion resistance is the bigger feature of the 20g high-pressure boiler tube. The user does not have to take any anti-corrosion measures. It also prevents secondary pollution of water quality.

Generally speaking, 20g high-pressure boiler tubes are mainly used for superheater tubes, reheater tubes, air guide tubes, main steam tubes, boiling water tubes, superheated steam tubes, and superheated steam tubes for locomotive boilers. With the subsequent development process, the 20g high-pressure boiler tube technology will continue to mature and progress.
