Product Description
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.
Another very important alloy steel tubes standard is ASTM A209 T1 for superheater usage. CTS may has exported more than 500 tons of ASTM A209 T1 tubes to Indonesia in last three years.
Furthermore, other mechanical tubes like ASTM A519 SAE4130, 40Cr, 20Cr are also our regular products.
We have the confidence to be one of your best suppliers for seamless alloy steel tubes and pipes.
Alloy Steel Boiler Tubes, Superheater Tubes, Heat Exchanger Tubes
