As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Stainless Steel Perforated Tube for Sieving and Filtering Applications. Designed for demanding industrial environments, these tubes offer exceptional durability, precise hole patterns, and corrosion resistance—making them an ideal choice for efficient sieving, liquid filtration, gas separation, and particle classification. Our tubes are meticulously crafted using advanced perforation technology, ensuring consistent quality and reliable performance across diverse sectors such as chemical processing, food & beverage, water treatment, mining, and pharmaceuticals.
Each perforated tube is manufactured from high-grade stainless steel (304, 316, or 316L) to withstand harsh conditions, including high temperatures, acidic or alkaline media, and continuous mechanical stress. The customizable hole shapes, sizes, and patterns allow you to achieve precise separation thresholds, while the smooth inner surface minimizes clogging and facilitates easy cleaning. With our factory's annual export value exceeding US$5 million, we serve clients across North America, South America, Europe, Asia, Africa, and Oceania, delivering products that meet rigorous international standards.
Key Features & Technical Specifications
- Premium Material: Made from high-quality stainless steel (SS304, SS316, SS316L) with excellent corrosion resistance and tensile strength.
- Precision Perforation: CNC-controlled punching ensures uniform hole diameter, spacing, and alignment, with tolerances as tight as ±0.05mm.
- Customizable Hole Patterns: Available in round, square, slotted, hexagonal, or decorative patterns – optimized for your specific sieving or filtering needs.
- Versatile Dimensions: Outer diameter from 10mm to 200mm, wall thickness from 0.5mm to 5mm, and length up to 6000mm (or as required).
- High Open Area: Open area ratio adjustable from 20% to 60%, balancing strength and flow capacity.
- Smooth Surface Finish: Options include mill finish, mechanical polishing, or deburring to reduce particle adhesion and improve hygiene.
- Durable End Connections: Plain, flanged, threaded, welded, or custom end treatments for easy integration into existing systems.
- Corrosion & Heat Resistance: Suitable for temperatures up to 800°C (for SS316L) and aggressive media such as acids, alkalis, and saltwater.
- Long Service Life: Robust construction resists deformation, fatigue, and wear, reducing replacement frequency and downtime.

Frequently Asked Questions
Q1: What stainless steel grades are available for the perforated tubes?
A: We offer SS304, SS316, and SS316L as standard options. Other grades such as duplex stainless steel or 904L can be supplied upon request, depending on your specific application requirements.
Q2: Can you provide custom hole patterns or diameters?
A: Absolutely. We manufacture custom hole shapes (round, square, slot, hexagon, etc.) and sizes based on your drawings or specifications. Minimum order quantity may apply for custom patterns; please consult our sales team.
Q3: What is the typical lead time for production?
A: For standard sizes and common materials, lead time is approximately 15–25 working days. Custom orders may take 20–35 working days, depending on complexity and quantity. We can expedite urgent orders subject to feasibility.
Q4: How do you ensure the consistency of hole size and spacing?
A: Our production uses CNC-controlled perforating presses with precision tooling. Each tube undergoes dimensional inspection and visual checks before packing. We also provide a quality inspection report upon request.
Q5: Are these tubes suitable for high-temperature applications?
A: Yes, especially SS316L grade, which can withstand continuous operating temperatures up to 800°C (1472°F) in oxidizing atmospheres. For higher temperatures, we recommend consulting our technical team for material selection.
Q6: Can you supply tubes with threaded or flanged ends?
A: Yes, we offer various end treatments including plain, threaded (NPT/BSP), flanged, grooved, or welded connections. Please specify the end type and dimensions when placing your order.
Q7: What is the minimum order quantity (MOQ) for these perforated tubes?
A: For standard stock items, MOQ is typically 50 pieces. For custom sizes, MOQ may be 100 pieces or more. Smaller trial orders are available for evaluation—please contact us for details.
