Seamless Alloy Steel Tubes

Alloy Steel Boiler Tubes, Superheater Tubes, Heat Exchanger Tubes

Size: Outside Diameter: 3/4” to 4”, Wall Thickness: 1mm to 20mm

Standard: SA-213M T11, T12, T5, T9, SA-209M T1A, ASTM A335 P11, P22, P5, P9, GB/T 5103

Application: Alloy Steel Tubes (Pipes) are High-pressure Boiler Tubes, which are mainly applied on Super Heaters, Reheaters, Water Walls, Economizers of the Super Critical and Ultra Super Critical Boilers, the Alloy Tubes required to have high creep rupture strength.

Seamless alloy steel tubes and pipes, especially standard ASTM A213, are widely used for boilers, heat exchangers, high pressure devices, superheaters, and reheaters. Due to seamless alloy steel tubes’ hardness and mechanical property, they are siutable for high temperature and high pressure circumstances. ASTM A213 Standard is Seamless Ferritic and Austenitic Alloy-steel Boiler, Superheater, and Heat-Exchanger tubes.

Beside alloy steel tubes, ASTM A213 also includes stainless tubes, which are also widely used for boilers, heat exchangers, and condensers.

Furthermore, other mechanical tubes like ASTM A519 SAE4130, 40Cr, 20Cr are also our regular products.
