Smls Pipe Steel Pipe GB5310-2017 20G High Pressure Boiler

Smls Pipe Steel Pipe GB5310-2017 20G High Pressure Boiler

Gb5310 high pressure boiler tubes are mainly used to manufacture high-quality carbon structural steel, 

alloy structural steel and stainless heat-resistant steel Seamless Steel Tubes for steam boiler tubes with 

high pressure and above. These boiler tubes work under high temperature and high pressure, and the 

tubes will also undergo oxidation and corrosion under the action of high-temperature flue gas and steam. 

Therefore, the steel tubes are required to have high lasting strength High oxidation resistance and good

 tissue stability.

Chemical composition test

 (1) Gb3087-2008 seamless steel tubes for low and medium pressure boilers. The chemical composition 

test method shall be in accordance with the relevant parts of gb222-84 and gb223 methods for chemical

analysis of iron, steel and alloy.

 (2) GB5310-2008 seamless steel tubes for high pressure boilers. The chemical composition test method

shall be in accordance with the relevant parts of gb222-84, methods for chemical analysis of steel and

alloy and gb223 methods for chemical analysis of steel and alloy.
