Product Features
The addition of titanium in ASTM A213 TP321 pipes provides exceptional corrosion resistance and reduces the risk of intergranular corrosion common in high-carbon steels. These stainless steel seamless tubes offer extended service life at high temperatures, making them ideal for heat exchangers, superheaters, boilers, and condensers. Available in various sizes and types including easy-to-install stainless steel hoses, our TP321 tubing is manufactured with high precision for demanding industrial applications.
