Since 1998, Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-quality wire mesh and perforated metal products. Our Durable Stainless Steel Helically Perforated Tube is designed for demanding industrial applications where precision, strength, and longevity are essential. Featuring a 6mm hole diameter, 2mm wall thickness, 304 stainless steel material, and a standard 4m length, this tube meets rigorous industry standards and offers excellent corrosion resistance, structural integrity, and uniform flow characteristics. Whether you need filtration components, protective sleeves, or ventilation ducts, our helically perforated tube delivers reliable performance backed by decades of manufacturing expertise.
Key Features & Technical Specifications
- Material: Premium 304 stainless steel – excellent resistance to rust, acids, and high temperatures, making it suitable for food processing, chemical, and marine environments.
- Helical Perforation Pattern: The spiral arrangement of holes ensures uniform distribution of flow, reduces clogging, and enhances structural strength compared to straight-row perforations.
- 6mm Hole Diameter: Ideal for medium-filtration applications, particle separation, and airflow control. The precise hole size is maintained consistently along the entire length.
- 2mm Wall Thickness: Provides robust mechanical strength while remaining lightweight enough for easy handling and installation. Suitable for moderate pressure applications.
- Standard 4m Length: Convenient for transportation and on-site cutting. Custom lengths are available upon request to fit specific project requirements.
- Standard Compliance: Manufactured in accordance with recognized industry standards for dimensional accuracy, material composition, and perforation quality. (Specific standard details available upon request.)
- Surface Finish: Mill finish as standard; optional brushed, polished, or passivated finishes for aesthetic or hygiene requirements.
- Versatile Applications: Used in oil & gas filtration, water treatment, agricultural grain drying, acoustic panels, machine guards, and architectural decorations.

Why Choose Our Helically Perforated Tube?
- Consistent Quality: Our tubes are manufactured using advanced CNC perforation equipment, ensuring every hole is precisely aligned and free of burrs. The helical pattern is maintained throughout the production run.
- Durability & Long Service Life: 304 stainless steel offers excellent resistance to oxidation, corrosion, and mechanical wear. The 2mm wall provides sufficient strength to withstand moderate mechanical loads and thermal cycling.
- Cost-Effective Solution: Compared to custom-machined tube alternatives, our helically perforated tube offers a more economical solution without compromising on quality or performance. The standard 4m length reduces waste and simplifies logistics.
- Easy Maintenance: The smooth internal surface and uniform hole pattern minimize dirt accumulation and allow for easy cleaning. In many applications, the tube can be cleaned by backflushing or simple wiping.
- Customization Available: While the standard product is widely used, we can adapt hole diameter, wall thickness, length, and end connections (threaded, flanged, or plain) to meet your exact specifications. Contact our engineering team for a tailored solution.
- Environmentally Friendly: 304 stainless steel is 100% recyclable, and our manufacturing process minimizes scrap. The long lifespan of the product reduces the need for frequent replacements, contributing to sustainable operations.
Applications Across Industries
- Filtration & Separation: Used in sand filters, water treatment diffusers, and oil-water separators. The 6mm holes are effective for retaining larger particles while allowing fluid flow.
- Ventilation & Air Distribution: Installed in HVAC systems, dust collectors, and air intake ducts. The helical pattern reduces noise and creates uniform airflow.
- Machine Guards & Safety Barriers: Provides protection around rotating machinery, conveyor belts, and robotic arms. The robust construction can withstand impact.
- Agricultural & Food Processing: Used in grain drying tubes, seed cleaning machines, and food washing drums. The smooth stainless steel surface is hygienic and easy to sanitize.
- Architectural & Decorative: Creates unique facade elements, sunshades, and privacy screens. The helical pattern adds a modern aesthetic to buildings.

Frequently Asked Questions (FAQ)
- Is this tube suitable for outdoor use? Yes, 304 stainless steel has good resistance to atmospheric corrosion, making it suitable for most outdoor environments. For highly corrosive coastal or chemical environments, we recommend 316L grade (available upon request).
- Can I order a custom length shorter than 4m? Absolutely. We can cut the tube to any length from 0.5m to 6m. Please specify your required length during quotation.
- What is the maximum operating temperature? 304 stainless steel can be used continuously at temperatures up to 870°C (1600°F) in intermittent service, and up to 925°C (1700°F) in continuous service. However, the perforated structure may slightly reduce the thermal limit depending on the application.
- Do you provide samples? Yes, we can provide small samples (e.g., 200mm length) for evaluation. Sample cost is negotiable, and shipping is at your account. Please contact our sales team.
- What is the lead time for a standard order? For standard 4m lengths with 6mm holes, typical lead time is 10–15 working days after order confirmation. Custom orders may require additional time.
- How are the tubes packaged for export? Tubes are bundled in plastic caps or wooden crates to prevent damage during transit. Individual tubes can be wrapped in protective film or paper upon request.
- Can the tube be threaded or flanged at the ends? Yes, we offer end finishing options such as threading (NPT/BSP), welding flanges, or plain ends. Please provide your specific requirements.
- What is the minimum order quantity? For standard sizes, the MOQ is 50 pieces. For custom specifications, please inquire; we can often accommodate smaller quantities for trial orders.
