SA179 U-Tubes for Heat Exchangers

Henan Bebon is a professional manufacturer of SA179 U-tubes for heat exchangers.
Why are SA179 U-tubes the ideal choice for your heat exchanger applications?
a. Excellent Thermal Conductivity
SA179 material is low carbon steel with extremely low carbon content. This results in a more uniform and dense metal grain structure, providing excellent thermal conductivity. In heat exchangers, this translates to higher heat transfer efficiency, quickly transferring heat from one fluid to another, thereby improving the overall energy efficiency of the equipment.
b. Excellent Cold Bending Formability (Key Advantage)
The core manufacturing process of U-tubes is cold bending. The low carbon characteristics of SA179 material give it excellent plasticity and toughness.
During the bending process, it effectively resists cracking and wrinkling, forming a smooth, uniform bending radius, ensuring smooth flow of fluid inside the tube, reducing stress concentration points, and thus extending the service life of the tube.
c. Good Surface Quality and Dimensional Accuracy
The standard requires the tubes to undergo scale-free bright annealing treatment. This brings two direct benefits:
Clean surface: Reduces impurities and oxide layers, avoiding contamination of fluids, and facilitating subsequent cleaning and maintenance.
Precise dimensions: The annealing process eliminates cold working stress, making the tubes dimensions (outer diameter, wall thickness) very stable and accurate, ensuring the tightness and strength of the expansion joint with the tube sheet.
