SA210 A1 boiler tube is a kind of seamless tube. The manufacturing method is the same as that for seamless pipes, but there are strict requirements for the steel grades used for manufacturing boiler tube. According to the use temperature, it is divided into two types: general boiler tube and high pressure boiler tube.
Perennial materials: high pressure boiler pipe, 20g high pressure boiler pipe, boiler pipe, Q235, 10 × 20 × 20g, 16Mn, ASTM / ASME (sa106b, c). 35 × 45 × 45 × Q345 (b.c.d), 27SiMn, L245, 40Cr, 35CrMo, 42CrMo, 15grmovg 12CrlMoVG, 1Cr5Mo, a335p11, a335p12, a335t22, a335t91, 16mndg, in accordance with national standards: structural pipe GB / t8162-2008, fluid pipe GB / t8163-2008, low and medium pressure boiler pipe gb3087-2008, high pressure boiler pipe GB5310-2008, medium and low pressure boiler pipe, fertilizer special pipe GB6479-2000, and seamless steel pipe of stone oil cracking pipe GB9948-2006.
1. General boiler pipes are mainly used to manufacture water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arch brick pipes, etc.
2. High pressure boiler pipe is mainly used to manufacture superheater pipe, reheater pipe, air pipe, main steam pipe, etc. of high pressure and ultra-high pressure boiler. The supply and demand trend of high-pressure boiler tube industry is generally stable, but the supply and demand situation of various sub industries will be further differentiated. Industry insiders pointed out that the most critical link is the use and promotion of new energy-saving and heat preservation 20g high-pressure boiler tube equipment.
