Benefits for Your Application

High Flow Efficiency: The helical slot design minimizes pressure drop while maximizing open area, achieving up to 30% open area depending on configuration.
Anti-Clogging Performance: Smooth, continuous slots prevent particle bridging and allow easy backwashing, reducing maintenance downtime.
Long Service Life: 316L stainless steel offers superior resistance to pitting, crevice corrosion, and stress corrosion cracking, even in high-temperature or saline environments.
Versatile Use: Ideal for water treatment, oil & gas well screens, food processing, chemical filtration, and mineral processing.
Easy Installation: Can be welded, threaded, or flanged to fit existing systems; custom end connections available.

Our Helically Perforated Tubes are manufactured using advanced CNC winding technology, ensuring every slot meets tight tolerances. Each tube undergoes rigorous quality checks including slot dimension measurement and pressure testing (optional). We have supplied these products to clients across North America, South America, Europe, Asia, and Africa, with annual export value exceeding US$5 million.

Frequently Asked Questions

What is the maximum operating temperature for this tube?
316L stainless steel can typically withstand temperatures up to 800°C (1472°F) in continuous service, but the actual limit depends on the environment. For high-temperature applications, we can recommend alternative materials or designs.
Can you supply tubes with a larger slot width, e.g., 1mm or 2mm?
Yes, we offer custom slot widths ranging from 0.1mm to 5mm. The 0.5mm slot is a standard option, but we can produce any size upon request.
How do I install this tube into a filter housing?
We can provide tubes with plain ends, threaded ends, flanges, or welding ends. Installation typically involves welding or clamping the tube into the housing. Our technical support team can advise on the best method for your system.
What is the typical open area percentage for this configuration?
For a 0.5mm slot with 2mm pitch, the open area is approximately 25%. This can be adjusted by changing the pitch or slot width.
Do you offer samples before bulk order?
Yes, we can provide samples (usually 300mm length) for quality evaluation. Please contact us for sample availability and shipping costs.
Is this tube suitable for well screen applications?
Absolutely. The helical design provides excellent strength against collapse while allowing efficient water or oil inflow. 316L is ideal for corrosive groundwater or seawater environments.
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is 10 pieces. For custom sizes, MOQ may vary; please consult our sales team.
Can you provide material certificates?
Yes, we can supply mill test certificates (MTC) for 316L stainless steel material upon request.
