ASTMA213 Stainless Steel Seamless U Tube

Seamless Stainless Steel U-tube is a specific type of heat exchanger tube that is bent into a"U"shape after the manufacturing process. It is crafted from a single, solid billet of stainless steel and, like other seamless tubes, has no weld joint. This seamless construction is crucial for maintaining structural integrity and reliability, especially in high-stress and corrosive environments. The unique U-shape allows for thermal expansion and contraction, making it ideal for shell and tube heat exchangers. It enables a single-pass fluid flow on the shell side and a multi-pass flow on the tube side, maximizing heat exchange efficiency and reducing the overall footprint of the heat exchanger.
