Product Description

20G SEAMLESS STEEL BOILER TUBE MADE IN CHINA FOR POWER PLANT

Alloy seamless steel pipe is a kind of seamless steel pipe, and its performance is much higher than that of ordinary seamless steel pipe, because this steel pipe contains more Cr, and its high temperature resistance, low temperature resistance and corrosion resistance performance are better than other seamless steel pipes. Incomparable, so alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries.
Standard:GB 5310
Seamless steel tubes and pipes for high pressure boiler

 
GB 5310 standard is applicable to steam boilers and pipeline seamless pipes for the manufacture of high pressure and above.

20G steel pipe is GB / 5310 national standard steel grade (foreign corresponding brands: Germany ST45.8, Japan stb42, America sa106b), which is the most commonly used boiler steel pipe.

GB / 5310 20G steel pipe has certain strength at normal and medium high temperature, low carbon content, better plasticity and toughness, and good cold and hot forming and welding performance.

 

GB 5310 20G Seamless steel tubes and pipes for high pressure boiler
20G (high quality carbon structural steel pipe) supplied according to GB5310 is used as heating surface pipe fittings, and the maximum wall temperature for long-term use is ≤ 450 ° C. when GB5310 20G seamless steel pipe is used as header and steam pipe, the long-term use temperature shall be ≤ 425 ° C.
