ASME SA249 TP321 pipes are particularly suitable for high-pressure equipment such as boilers, superheaters, heat exchangers and condensers.
TP321 stainless steel welded pipes belong to the austenitic stainless steel series, and the main components include chromium, nickel and a small amount of titanium. The addition of chromium gives it excellent corrosion resistance and can maintain good stability in a variety of corrosive media; the addition of nickel enhances the material's high temperature resistance, allowing it to maintain high strength and toughness in high temperature environments.
The ASME SA249 TP321 stainless steel pipes supplied by GNEE include multiple fine links such as raw material preparation, cutting, rolling, welding, solution treatment, pickling and passivation.
