For over two decades, Anping County Boli Hardware Wiremesh Products Factory (established 1998) has been a trusted manufacturer of high-quality metal products. Our 316L Stainless Steel Straight Seam Welded Perforated Pipe with a 2mm wall thickness and 10mm hole diameter represents the perfect blend of precision engineering and durable material. Designed for demanding industrial applications, this pipe offers exceptional corrosion resistance, structural integrity, and reliable performance. With an annual export value of US$5–10 million and shipments from major Chinese ports like Tianjin, Qingdao, Shanghai, and Foshan, we deliver globally to North America, Europe, Southeast Asia, and beyond.
Our perforated pipe is manufactured using advanced straight seam welding technology, ensuring a smooth, uniform weld seam that maintains the pipe's strength and consistency. The 316L stainless steel grade provides superior resistance to pitting, crevice corrosion, and chlorides, making it ideal for marine, chemical, and food processing environments. The 2mm wall thickness offers robust structural support, while the 10mm hole diameter allows efficient flow, filtration, or ventilation. Whether you need it for liquid filtration, sieving, protective guards, or sound attenuation, this pipe delivers consistent results.

Advantages & Customer Benefits
Our 316L perforated pipe offers several distinct advantages over alternative materials or manufacturing methods:
- Exceptional Corrosion Resistance: 316L contains molybdenum, providing superior resistance to acids, chlorides, and seawater. Ideal for chemical plants, oil & gas, and marine applications.
- High Strength-to-Weight Ratio: The 2mm wall thickness provides sturdy support without excessive weight, simplifying installation and reducing structural load.
- Precise, Consistent Perforations: CNC-controlled punching ensures uniform hole size and spacing, critical for filtration accuracy and flow control.
- Smooth Weld Seam: Straight seam welding minimizes internal ridges, reducing pressure drop and improving cleaning efficiency in food and pharmaceutical processing.
- Cost-Effective & Lead Time: As a direct manufacturer, we offer competitive pricing and short lead times. Our annual output capacity supports large-volume orders.

Frequently Asked Questions
1. What is the difference between 316L and 304 stainless steel for perforated pipes?
316L contains molybdenum, which provides enhanced resistance to pitting and crevice corrosion in chloride environments. 304 is suitable for less aggressive conditions. 316L is recommended for seawater, chemical, and pharmaceutical applications.
2. Can you provide custom hole patterns or diameters?
Yes, we offer customization. You can specify hole diameter, center-to-center spacing, pattern (staggered, straight row), and even slot shapes. Our tooling covers a wide range of sizes.
3. What is the maximum length you can produce?
Standard length is 6 meters. For longer lengths, we can produce up to 12 meters depending on the diameter and wall thickness. Please inquire for special requirements.
4. Is the weld seam completely smooth on the inside?
Our straight seam welding process yields a smooth internal weld bead. For applications requiring extremely clean interiors, we can perform grinding or pickling to further reduce roughness.
5. What is the typical lead time for custom orders?
Lead time varies based on quantity and complexity. Typically, standard sizes take 15–20 days after order confirmation. Custom orders may require 25–35 days. We can expedite for urgent projects.
6. Do you provide samples for testing?
Yes, we can provide small sample pieces or short pipe sections for material testing and dimensional verification. Sample cost is negotiable, and shipping is at your expense.
7. How do you ensure the perforated pipe does not deform during welding?
We use jigs and fixtures to hold the pipe during welding, and we control heat input to minimize distortion. Post-weld straightening is performed if needed.
8. What packaging do you use for export?
We pack pipes in bundles with steel straps, wrapped in waterproof plastic, and placed in wooden crates or pallets for container loading. Custom packaging is available upon request.
