Advantages & Customer Benefits
- Uniform Flow Distribution: The spiral pattern ensures even fluid flow across the entire tube surface, enhancing filtration efficiency and reducing pressure drop.
- High Structural Integrity: The spiral punching process maintains the tube's strength, making it suitable for high-pressure applications.
- Corrosion Resistance: 304 stainless steel provides excellent resistance to oxidation and many chemicals, prolonging service life in harsh environments.
- Easy Cleaning & Maintenance: The smooth surface and spiral design minimize particle entrapment, allowing quick backwashing or chemical cleaning.
- Customizable to Your Needs: We offer flexible customization on hole size, pitch, tube diameter, length, and end finishing (plain, threaded, flanged).
- Precision Manufacturing: Our CNC punching machines ensure consistent hole dimensions and spacing, meeting tight tolerances (e.g., ±0.05mm).
- Wide Range of Applications: From water filtration and oil refining to pneumatic conveying and sound attenuation, our tubes are used globally.

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ) for custom spiral punched tubes?
A: The MOQ depends on tube diameter and length, typically starting from 100 pieces for standard sizes. For smaller quantities, please consult our sales team – we can often accommodate prototypes or samples. -
Q: Can you provide tubes with different hole shapes (e.g., square, slot)?
A: While our standard spiral punching is round, we can also produce square, hexagonal, or slot holes with a spiral pattern upon request. Please specify your requirements. -
Q: What is the lead time for a custom order?
A: For standard sizes, production takes about 15–20 working days. For complex customizations, allow 25–30 working days. Expedited service is available for urgent orders. -
Q: Do you offer samples? How can I get one?
A: Yes, we provide samples. You can request a sample by sending an inquiry with your specifications. Sample cost is applicable but will be returned on bulk orders. -
Q: How do you ensure the hole size accuracy?
A: We use CNC-controlled punching machines with automatic tool compensation. Each batch is inspected with digital calipers and a hole gauge to ensure ±0.05mm tolerance. -
Q: Can you weld or attach end fittings to the tubes?
A: Yes, we can provide end finishing such as plain cut, threaded, flanged, or welded caps. We also offer custom welding of flanges or couplings. -
Q: What surface treatments are available besides pickling and polishing?
A: We can also supply electropolished, passivated, or powder-coated surfaces. For certain applications, we recommend a specific finish to enhance corrosion resistance or cleanability. -
Q: Is your factory certified for quality management?
A: We follow strict internal quality control procedures. While we do not list specific certifications, we are capable of meeting international standards such as ASTM A269 or comparable requirements. Third-party testing can be arranged upon request.
