Custom Spiral Heat Exchanger Coil Metal Tube Bending for Fluid Heating Systems

The spiral heat exchanger coil is formed using CNC-controlled, one-piece tube bending, eliminating segmented welds and preventing leaks. Its compact spiral design significantly increases the heat transfer area. Made of stainless steel, it withstands high and low temperatures, resists acid and alkali corrosion, and features high structural strength, ensuring it remains distortion-free even under long-term operating conditions.

FAQ

Q1: How does a one-piece spiral coil compare to a welded version?
A1: CNC-machined in a single step with no welds, it eliminates leaks, reduces stress on the tubing, and offers greater resistance to high and low pressures, ensuring more stable long-term operation.

Q2: How do you ensure consistent pitch dimensions for each coil turn?
A2: Dedicated CNC tube bending equipment is paired with custom tooling, and bending parameters are precisely controlled to minimize dimensional errors.

Q3: Can the coil’s dimensions be customized to fit the dimensions of the channel housing?
A3: We support full-range customization, allowing adjustments to the coil diameter, number of turns, and joint angles to fit the equipment.

Q4: What factors should be prioritized when designing bent tubes?
A4: Tube diameter, wall thickness, bend radius, material, and operating conditions. Appropriate parameters can improve machining accuracy and the performance of the finished product.

Q5: How does the bending radius affect the quality of bent tubes?
A5: An appropriate bending radius prevents wrinkling, flattening, and stress concentration, ensuring dimensional stability and extending service life.

Q6: What are the advantages of seamless bent tubes compared to welded ones?
A6: They reduce the number of welds, offer higher structural strength, simplify assembly, and lower costs. They also eliminate the risk of weld leaks or fractures, resulting in greater reliability.
