As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory is proud to offer our Longitudinal Seam Welded Perforated Tube. This product is engineered to deliver consistent performance in demanding industrial applications, backed by a 1-year warranty and a comprehensive Mill Test Report for each batch. Our tubes are manufactured in strict compliance with international standards, ensuring reliable quality and dimensional accuracy. Whether you need filtration, screening, or structural support, our perforated tubes provide a cost-effective solution without compromising on strength.
Each tube is produced using advanced longitudinal seam welding technology, which creates a uniform, leak-proof seam along the entire length. The perforations are precisely punched to meet your specific open area and hole pattern requirements. We offer a wide range of materials, including carbon steel, stainless steel, and galvanized options, to suit various environments. The tubes are available in diameters from 20mm to 300mm, lengths up to 6 meters, and wall thicknesses from 0.5mm to 5mm – all customizable to your project needs.
Key Features & Technical Specifications
- Longitudinal Seam Welding – Ensures high structural integrity and uniform strength along the tube, reducing the risk of failure under pressure.
- Precision Perforation – Holes are cleanly punched with consistent diameter and spacing, available in round, square, or slot shapes.
- Standard Compliance – Our tubes are manufactured to meet common industry standards (e.g., ASTM A513, DIN 2394) – proof of conformance can be provided upon request.
- Mill Test Report Included – Each shipment comes with a detailed report covering chemical composition, mechanical properties, and dimensional verification.
- 1-Year Warranty – We stand behind the quality of our product, covering manufacturing defects and workmanship.
- Corrosion Resistance – Available in galvanized or stainless steel options for enhanced durability in harsh environments.
- Customizable Dimensions – Tube diameter, length, wall thickness, hole size, and pattern can be tailored to your exact specifications.
