Key Product Features
- High Purity Copper Material: Made from C12200 or C11000 copper with excellent thermal conductivity (≈400 W/m·K) and corrosion resistance.
- Spiral / Helical Design: Optimized geometry increases surface area and enhances heat transfer efficiency, reducing energy consumption.
- Precision Manufacturing: CNC‑controlled bending and forming ensure tight tolerances (±0.1 mm) and consistent coil pitch, minimizing pressure drop.
- Full Mill Test Report: Each batch is tested for chemical composition, mechanical properties, and dimensional accuracy – report included with every shipment.
- Standard Compliance: Meets ASTM B75, ASTM B111, and other relevant industry standards; available with additional certifications upon request.
- 1‑Year Warranty: Covers manufacturing defects; we stand behind the quality of our products.

Advantages & Customer Benefits
- Improved Efficiency: The spiral structure increases the heat transfer coefficient by up to 30% compared to straight tubes, reducing system size and cost.
- Space Saving: Compact coil design fits easily into heat exchangers, condensers, and evaporators, ideal for limited installation spaces.
- Easy Installation & Maintenance: Smooth internal surface reduces fouling and scaling; tube ends can be flared or brazed for quick connections.
- Versatile Applications: Widely used in HVAC systems, water chillers, solar water heaters, industrial heat recovery, and refrigeration units.
- Customizable Options: We can adjust dimensions, coil geometry, and end terminations (plain, flared, or threaded) to match your exact requirements.

Frequently Asked Questions (FAQ)
Q1: What materials are available for the spiral heat exchange tube?
A: Standard material is copper (C12200 or C11000). Other copper alloys (e.g., C70600, C71500) are available upon request. We can also provide a Mill Test Report for the material composition.
Q2: Do you offer custom sizes and coil configurations?
A: Yes, we can customize outer diameter, wall thickness, coil pitch, total length, and end terminations to meet your specific design. Please provide your drawing or requirements for a tailored solution.
Q3: What certifications do you have for this product?
A: Our tubes are manufactured in compliance with international standards such as ASTM B75 and ASTM B111. Additional certifications (e.g., EN, JIS, or customer‑specific) can be arranged upon request. Please note that we do not automatically include third‑party certifications unless specified in the order.
Q4: Is the Mill Test Report included with every shipment?
A: Yes, a Mill Test Report (MTR) covering chemical analysis, mechanical properties, and dimensional inspection is provided with each batch. This ensures traceability and quality assurance.
Q5: What is the typical lead time?
A: For standard sizes (e.g., 10 mm OD, 1 mm wall), lead time is approximately 15–20 working days. Custom orders may require 25–30 working days, depending on complexity. We can expedite for urgent projects subject to availability.
Q6: What is the warranty coverage?
A: We offer a 1‑year warranty against manufacturing defects. This covers issues such as material failure, leaks, or dimensional non‑conformance. The warranty does not cover damage caused by improper installation, misuse, or corrosion due to incompatible fluids.
Q7: How do you package the tubes for export?
A: Each coil is individually wrapped with protective foam or plastic, then packed in sturdy wooden crates or cartons, depending on size. For large orders, we use palletized packaging to ensure safe sea freight. We can also customize packaging per your instructions.
Q8: Can I get a sample before placing a bulk order?
A: Yes, we provide samples for evaluation. The sample cost is usually deducted from the first production order. Please contact our sales team to discuss sample requirements and shipping.
