As a trusted manufacturer with over two decades of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our premium 316L Stainless Steel Longitudinal Seam Welded Perforated Tube with a 2mm wall thickness and 8mm hole diameter, compliant with ASTM A554 standards. Since our establishment in 1998, we have been dedicated to delivering high-quality perforated metal solutions that meet the rigorous demands of global industries. This tube combines the exceptional corrosion resistance of 316L stainless steel with the structural integrity of longitudinal seam welding, making it an ideal choice for applications requiring durability, precision, and longevity.
Our perforated tube is engineered to provide consistent performance in harsh environments, including chemical processing, food and beverage production, water treatment, and architectural projects. The 2mm wall thickness offers robust strength while maintaining formability, and the 8mm round holes are precisely punched to ensure uniform flow and filtration characteristics. Each tube undergoes strict quality control checks to guarantee dimensional accuracy and compliance with ASTM A554 specifications.
Key Features & Technical Specifications
- Superior Material: 316L stainless steel contains molybdenum for enhanced resistance to chlorides, acids, and pitting corrosion – ideal for marine and chemical environments.
- Longitudinal Seam Welding: The tube is formed and welded along its length using advanced techniques, ensuring a smooth, strong weld seam that minimizes stress concentrations and improves fatigue resistance.
- Precise Perforation: 8mm diameter holes are arranged in a staggered pattern (60° or 45° available) to maximize open area while maintaining structural integrity. Hole tolerance is within ±0.1mm.
- Consistent Wall Thickness: 2mm wall provides excellent strength-to-weight ratio, suitable for pressure applications and heavy-duty screening.
- ASTM A554 Compliance: Manufactured in accordance with the American standard for welded stainless steel mechanical tubing, ensuring mechanical properties and dimensional tolerances.
- Customizable Options: Available in various lengths (up to 6 meters), end finishes (plain, beveled, threaded), and surface treatments (pickling, passivation, polishing).

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316L stainless steel for perforated tubes?
A: 316L contains molybdenum, which provides significantly better resistance to chlorides and acidic environments. It is recommended for marine, chemical, and food processing applications where corrosion resistance is critical. -
Q: Can you customize the hole pattern or spacing?
A: Yes, we offer customizable hole patterns including staggered, straight, or custom pitches. Please provide your drawing or specifications for a tailored solution. -
Q: What is the maximum length available for this tube?
A: Standard lengths are 6 meters, but we can produce tubes up to 12 meters upon request, subject to transportation limitations. -
Q: Is this tube suitable for high-pressure applications?
A: The 2mm wall thickness and longitudinal seam weld make it suitable for moderate pressure applications. For specific pressure ratings, please consult our engineering team. -
Q: Do you provide surface treatment options like pickling or passivation?
A: Yes, we offer pickling, passivation, and mechanical polishing to improve corrosion resistance and appearance. Please specify your requirement. -
Q: What is the typical lead time for an order?
A: Lead time depends on quantity and customization. Standard tubes typically ship within 15–20 working days after order confirmation. Express delivery is available upon request. -
Q: How do you ensure the quality of the tubes?
A: We perform dimensional inspection, visual weld inspection, and hydrostatic testing (optional) in accordance with ASTM A554. A mill test certificate is provided with each shipment. -
Q: Can I request a sample before placing a bulk order?
A: Yes, samples are available for evaluation. Please contact our sales team to arrange sample shipment, and we will deduct the cost from your first bulk order.
