Anping County Boli Hardware Wiremesh Products Factory — established in 1998 with annual export value of US$5–10 million — presents our premium 304 Stainless Steel Helically Perforated Tube with a precise 0.5mm hole diameter and 2mm wall thickness, specifically engineered for high-efficiency filtration applications. As a trusted manufacturer with over two decades of experience, we combine advanced helical perforation technology with strict quality control to deliver tubes that offer exceptional flow distribution, mechanical strength, and corrosion resistance. Whether you need fine particle separation, liquid-solid filtration, or gas diffusion, this product provides a reliable, long-lasting solution that meets the demands of rigorous industrial environments.
Key Features & Technical Specifications
- Material: Premium 304 stainless steel ensures excellent corrosion resistance, durability, and hygiene — ideal for food, chemical, and pharmaceutical filtration.
- Hole Diameter (0.5mm): Uniform micro-perforations enable precise particle retention while maintaining high flow rates.
- Wall Thickness (2mm): Robust construction provides structural integrity under high pressure and mechanical stress.
- Helical Perforation Pattern: The unique helical arrangement optimizes fluid distribution, reduces clogging, and enhances backwash efficiency compared to standard straight-hole patterns.
- Customizable Dimensions: Available in various lengths, diameters, and end configurations (plain, threaded, flanged) to fit your specific system.
- Surface Finish Options: Pickling, passivation, or electropolishing available upon request for improved cleanliness and corrosion resistance.

Advantages & Benefits for Your Filtration System
- High Filtration Precision: The 0.5mm hole diameter effectively retains particles down to ~500 microns, making it suitable for coarse filtration, strainers, and support layers for finer media.
- Superior Flow Distribution: The helical pattern minimizes turbulence and pressure drop, ensuring uniform flow across the entire tube surface — critical for applications like water treatment, oil refining, and chemical processing.
- Reduced Clogging & Easy Cleaning: The smooth helical slots allow trapped solids to be easily dislodged during backwashing, extending service life and reducing maintenance downtime.
- Mechanical Strength: With 2mm wall thickness, the tube withstands high operating pressures (up to 10 bar, depending on diameter) and resists deformation under heavy loads.
- Corrosion Resistance: 304 stainless steel offers excellent resistance to a wide range of chemicals, moisture, and temperatures up to 800°C (intermittent), making it ideal for harsh environments.
- Customizable to Your Needs: We offer flexibility in diameter, length, end connections, and surface finishes — no minimum order quantity (MOQ) for prototypes.
Typical Applications
- Liquid-solid filtration in water treatment plants, desalination, and wastewater systems.
- Gas filtration and diffusion in pneumatic conveying, aeration, and exhaust systems.
- Strainer elements for oil, gas, and petrochemical industries.
- Support cages for filter bags, cartridges, and membrane elements.
- Food and beverage processing — juice, beer, wine, and edible oil filtration.
- Pharmaceutical and chemical processing where sanitary conditions are required.

Frequently Asked Questions (FAQ)
-
Q: What is the exact hole diameter tolerance?
A: Our standard tolerance for 0.5mm hole diameter is ±0.05 mm. Tighter tolerances are available upon request for critical applications. -
Q: Can you provide tubes with different wall thicknesses?
A: Yes, we offer custom wall thicknesses from 1.0mm to 4.0mm depending on the diameter and material. Please specify your requirements. -
Q: How do I determine the open area ratio for my application?
A: The open area ratio depends on the hole spacing and pattern. For standard helical pattern, the ratio is approximately 15%. We can adjust spacing to achieve higher or lower ratios as needed. -
Q: Is the tube suitable for high-temperature environments?
A: 304 stainless steel can withstand continuous operating temperatures up to 800°C (intermittent) and 925°C for short periods. However, performance may vary based on the specific conditions. Please consult our technical team for your application. -
Q: What surface finish options are available?
A: Standard finish is pickled and passivated. We also offer electropolishing, mirror polish, and other finishes upon request for improved hygiene or corrosion resistance. -
Q: Do you provide samples for testing?
A: Yes, we offer sample tubes (100–300mm length) for evaluation. Shipping cost is applicable. Please contact our sales team to arrange. -
Q: What is the typical lead time for custom orders?
A: For standard dimensions, lead time is 10–15 working days. For custom specifications, typically 20–25 working days depending on quantity and complexity. -
Q: Can the tube be used as a support for filter bags?
A: Absolutely. The 2mm wall thickness provides excellent rigidity, making it ideal as a support cage for filter bags, cartridges, or membrane elements. The helical pattern helps distribute the load evenly.
