Stainless steel heat exchange tubes are common tubular heat exchange elements. In conventional heat exchange scenarios, they are standard cylindrical. However, they are not just straight tubes…
In addition to straight tubes, stainless steel heat exchange tubes are classified by shape, including corrugated tubes, U-shaped tubes, coils, spiral reinforced tubes, serpentine tubes and special-shaped tubes, each of which has different characteristics.
1. Corrugated tubes: The corrugated inner or outer wall is formed by a special process to enhance the fluid turbulence effect, and the heat transfer efficiency is increased by 30-50% compared with straight tubes.
2. U-shaped tubes: A single steel tube is bent into a U shape, and both ends are fixed on the same tube sheet, allowing free expansion and contraction to avoid temperature difference stress.
3. Coils: The steel tube is bent into a spiral or flat coil shape, which significantly increases the heat exchange area.
4. Spiral reinforced tubes:
① Spiral groove tubes: Spiral grooves are squeezed out of the tube wall to enhance turbulence through secondary flow, and the heat transfer efficiency is 2-4 times higher than that of light tubes.
②Spiral flat tube: The cross section is oblong, and spiral flow is formed in the tube side and shell side at the same time, which enhances double-sided heat transfer.
③Spiral fin tube: The spiral fins are rolled on the outer surface to increase the heat exchange area and promote the thinning of the liquid film, thereby improving the condensation/evaporation efficiency.
5.Serpentine tube: Continuous bending forms a serpentine path to extend the fluid residence time.
6.Special-shaped tube: Such as square and triangular tubes, used for special flow channel design.
The shape design of stainless steel heat exchange tubes is based on the core goals of enhancing heat transfer efficiency and adapting to complex working conditions. Through structural innovations such as corrugation, spiral, and bending, it meets the heat transfer needs of different industrial scenarios.
