As a leading manufacturer from Anping County Boli Hardware Wiremesh Products Factory (established in 1998), we specialize in producing high-quality perforated metal products. Our 304 Stainless Steel Straight Seam Welded Perforated Pipe with 1.5mm wall thickness is engineered for demanding filtration applications. This product combines the corrosion resistance of 304 stainless steel with precise perforation and robust welded construction, ensuring reliable performance in liquid and gas filtration systems. With over two decades of export experience and annual export value of US$5-10 million, we deliver consistent quality to global markets including North America, Europe, and Southeast Asia.
Our perforated pipe is manufactured using advanced straight seam welding technology, which provides a smooth, uniform interior surface and excellent structural integrity. The 1.5mm wall thickness offers enhanced durability while maintaining sufficient open area for efficient filtration. The pipe is available in various diameters and lengths, with customizable hole patterns (round, square, or slotted) to meet specific flow rate and particle retention requirements.
Key Features & Benefits
- Material Excellence: 304 stainless steel provides excellent resistance to corrosion, oxidation, and high temperatures, making it suitable for food processing, chemical, and pharmaceutical industries.
- Precision Perforation: Holes are punched with tight tolerances (typically ±0.1mm), ensuring consistent filtration performance and preventing clogging.
- Straight Seam Welding: The longitudinal weld is fully fused and ground smooth, eliminating weak points and reducing pressure drop.
- Customizable Dimensions: Outer diameter from 20mm to 200mm, wall thickness from 0.8mm to 3.0mm (1.5mm as standard), and length up to 6 meters per piece.
- Versatile Applications: Ideal for water treatment, oil filtration, gas separation, mining slurry screening, and architectural decorative purposes.
- Cost-Effective Solution: Compared to seamless pipes, our welded perforated pipes offer competitive pricing without compromising quality.

Frequently Asked Questions
Q1: What is the maximum length you can produce?
A: Standard length is 3 meters, but we can customize up to 6 meters per piece. For longer lengths, we can also provide welding joints or connectors.
Q2: Can you provide samples before bulk order?
A: Yes, we offer samples (usually 1-2 pieces) for quality evaluation. Sample cost is negotiable, and we can deduct it from the formal order.
Q3: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 100 pieces. For custom sizes, MOQ may be higher depending on the complexity. We can discuss smaller quantities for trial orders.
Q4: How do you ensure the holes are evenly distributed?
A: Our CNC punching machines ensure precise hole spacing with tolerances within ±0.1mm. Each batch is inspected using a template and coordinate measuring machine.
Q5: Is this pipe suitable for high-pressure applications?
A: The 1.5mm wall thickness provides good strength for moderate pressure (up to 10 bar, depending on diameter). For high-pressure systems, we recommend thicker walls or reinforcement. Please provide your working pressure for a customized solution.
Q6: What is the lead time for production?
A: For standard sizes, lead time is 15-20 working days after order confirmation. Custom orders may take 25-30 days. We can expedite for urgent orders subject to availability.
Q7: Can you provide a material certificate?
A: Yes, we can provide mill test certificates for 304 stainless steel material upon request, confirming chemical composition and mechanical properties.
Q8: What payment terms do you accept?
A: We accept T/T, L/C, and Western Union. For new customers, 30% deposit and 70% balance before shipment is typical. Flexible terms can be discussed for long-term cooperation.
