Stainless Steel ASTM A213 TP316L U Bend Tube For Heat Exchanger
A213 TP316L is a high-quality austenitic stainless steel tube manufactured according to the ASTM A213 standard. This standard covers seamless ferritic and austenitic alloy steel tubes for use in high-temperature and high-pressure environments such as heat exchangers, boilers, superheaters, and furnaces. The U-Bend Tube is specifically designed for applications where tight curvature is needed, and it is commonly used in heat exchangers and condensers. TP316L is a low-carbon version of TP316, which provides enhanced weldability and corrosion resistance, making it ideal for a variety of industrial applications.
