Bent Finned Tubes: Optimizing Heat Transfer for Complex Spaces
A bent finned tube is essentially a finned tube that has been precisely formed into a specific curvature – U-bends, coils, serpentine shapes, or custom angles – after the fins are attached. The fins, typically helical (spirally wound) or longitudinal, are securely bonded (often welded) to the base tube. The bending process requires specialized expertise to maintain the integrity of both the tube and the fin attachment without compromising performance.

ASTM A179 U Bend Heat Exchangers Tube
After U bend (cold forming), heat treatment of bending portion may be required. nitrogen generating machine (to protect stainless steel tube surface during annealing). Temperature is controlled through the entire heat-treated area by fixed and portable infrared pyrometers.
