Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer of perforated metal products with an annual export value of US$5–10 million, serving markets across North America, Europe, Asia, and Oceania. Our 2 Year Warranty Stainless Steel Helically Perforated Tube 316L with 1.5mm diameter holes and 30% open area is designed to deliver exceptional durability, precise filtration, and uniform flow distribution. This product combines the corrosion resistance of 316L stainless steel with a unique helical perforation pattern, making it an ideal choice for demanding industrial applications where reliability and performance are critical.

Below are the key features and technical specifications of our helically perforated tube:

Material	316L Stainless Steel (Low Carbon, Excellent Corrosion Resistance)
Hole Diameter	1.5 mm (±0.05 mm tolerance)
Open Area	30% (Optimized for flow and strength)
Perforation Pattern	Helical (spiral winding) – ensures uniform hole distribution and structural integrity
Tube Outer Diameter	Customizable (typically 20mm – 200mm, or as required)
Wall Thickness	0.5mm – 3.0mm (available upon request)
Length	1m – 6m (custom lengths available)
Surface Finish	Pickling & Passivation, Mill Finish, or as specified
Warranty	2 Years (against manufacturing defects)

Product Advantages & Benefits

Superior Corrosion Resistance – 316L stainless steel contains molybdenum, providing excellent resistance to chlorides, acids, and harsh environments, ideal for chemical, marine, and food processing applications.
Uniform Perforation & Flow – The helical design ensures consistent hole spacing along the entire tube length, resulting in uniform liquid/gas distribution and high filtration efficiency.
High Mechanical Strength – The helical structure adds rigidity compared to straight perforated tubes, allowing the tube to withstand higher pressure and mechanical stress without deformation.
30% Open Area Balance – This open area ratio offers a good compromise between flow capacity and structural integrity, making it suitable for both filter elements and structural supports.
Precision Manufacturing – Our advanced CNC perforating machines and laser cutting ensure hole diameter tolerance within ±0.05mm, delivering consistent quality batch after batch.
Customizable Dimensions – Outer diameter, wall thickness, length, and end connections (plain, threaded, flanged) can be tailored to your specific requirements.
2-Year Warranty – We stand behind the quality of our product with a full two-year warranty, giving you peace of mind for your project.

Typical Applications

Water & wastewater filtration – self-cleaning filter screens, intake strainers
Oil & gas industry – well screens, sand control tubes
Chemical processing – catalyst support, distributor tubes
Food & beverage – juice extraction, beer brewing filtration
Architectural design – decorative ventilation, sound-absorbing panels
Pharmaceutical – fine filtration and separation

Frequently Asked Questions (FAQ)

Q: What is the difference between 316 and 316L stainless steel?
A: 316L has a lower carbon content (max 0.03%) compared to 316 (max 0.08%), which provides better weldability and reduces the risk of intergranular corrosion in welded sections. 316L is preferred for applications requiring high corrosion resistance after welding.
Q: Can the open area be customized to a different percentage?
A: Yes, we can adjust the hole diameter, pitch, and pattern to achieve open areas from 10% to 60% as needed. Please contact our sales team with your specific requirements.
Q: What is the maximum length of a single tube?
A: Standard lengths are up to 6 meters. For longer tubes, we can provide butt-welded sections or seamless connections upon request. Please inquire for custom lengths.
Q: Does the helical perforation affect the tube's strength?
A: The helical pattern actually enhances the tube's structural integrity compared to straight longitudinal perforations, as the spiral arrangement distributes stress more evenly. It is commonly used in high-pressure filter applications.
Q: Is the 2-year warranty applicable to all sizes?
A: Yes, all our 316L stainless steel helically perforated tubes come with a 2-year warranty against manufacturing defects, regardless of size or customization.
Q: What surface treatments are available?
A: Standard finish is mill finish or pickling & passivation. We can also provide electropolishing, mirror polishing, or powder coating for specific applications. Please specify your requirement.
Q: Do you offer free samples?
A: We can provide sample pieces (limited length) for evaluation. The cost of sample and shipping may be charged and later refunded with bulk orders. Please contact us for details.
Q: What is the lead time for a typical order?
A: For standard sizes, lead time is approximately 15–25 working days. Custom orders may require 20–30 working days depending on complexity and quantity. We always confirm delivery schedule before order confirmation.
