BOILER TUBE and PIPE

Boiler Tube is a kind of seamless steel pipe.Produce technique is the same as seamless steel pipes also,but there are strict requirements for the steel grade used to produce.According to the use of temperature can divided into general boiler tube and high pressure boiler tube two kinds.

01 The application of boiler tubes

General boiler tubes are mainly used to manufacture water-cooled wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc.

02 The application of boiler tubes

High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam pipes, etc. for high-pressure and ultra-high-pressure boilers.
