Seamless alloy steel tubes and pipes, especially standard ASTM A213, are widely used in boilers, heat exchangers, high-pressure units, superheaters and reheaters. Due to the hardness and mechanical properties of seamless alloy steel pipes, they are suitable for high temperature and high pressure environments. ASTM A213 standard for seamless ferritic and austenitic alloy steel boiler, superheater and heat exchanger tubes.
In addition to alloy steel pipe, ASTM A213 also covers stainless steel pipe, which is also widely used in boilers, heat exchangers, and condensers.
In addition, other mechanical pipes such as ASTM A519 SAE4130, 40Cr, 20Cr are also our regular products.
