Astm A192 Od 610mm Seamless Steel Boiler Pipe

Product Description

ASTM A192 High quality seamless Steel Boiler Tube/pipe

Production

Boiler tube is a kind of seamless tube. The manufacturing method is the same as that of seamless pipe

but there are strict requirements for the steel grade used in the manufacture of steel pipe. According to

the service temperature, it is divided into general boiler tube and high-pressure boiler tube.

Generally, the service temperature of boiler tubes is below 350 ℃, and domestic tubes are mainly made

of No. 10 and No. 20 carbon structure steel hot-rolled tubes or cold drawn tubes.

 High pressure boiler tubes are often in high temperature and high pressure conditions when in use, and the

tubes are in the operation of high temperature flue gas and steam

When used, oxidation and corrosion will occur. The steel pipe is required to have high lasting strength, high

anti-oxidation and corrosion performance and good structural stability.

seamless Steel Boiler Tube/pipe are usually used in the following scope:

1.General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated

steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes.

2.High pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air ducts,

main steam tubes, etc. of high-pressure and ultra-high-pressure boilers.
