Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer since 1998 — proudly presents our Longitudinal Seam Welded Perforated Tube made from premium 316 Stainless Steel. With a precise hole diameter of 2mm, 1.5mm wall thickness, 200mm outer diameter, and standard 4m length, this tube is engineered for demanding industrial applications requiring high strength, corrosion resistance, and uniform perforation. Our longitudinal seam welding process ensures a smooth, durable joint that maintains structural integrity under pressure and temperature variations. Whether you need filtration elements, shielding sleeves, or structural support components, this product delivers consistent performance and long service life.
Key Features & Technical Specifications
- Material: 316 Stainless Steel — excellent resistance to chloride corrosion, acids, and high temperatures (up to 800°C). Ideal for marine, chemical, and food processing environments.
- Perforation Pattern: Round holes, 2mm diameter, arranged in staggered rows for optimal flow distribution and particle retention. Open area can be customized upon request.
- Wall Thickness: 1.5mm — balances strength with weight, suitable for moderate pressure applications.
- Outer Diameter: 200mm (8 inches) — standard size; other diameters from 50mm to 500mm are available.
- Length: 4m per piece — can be cut to specific lengths or supplied in continuous coils for smaller diameters.
- Welding Process: Longitudinal seam welded using TIG/GTAW method, ensuring full penetration, smooth bead, and no distortion. Weld zone is ground flush for a clean interior surface.
- Surface Finish: Mill finish standard; optional pickling, passivation, or mechanical polishing for enhanced corrosion resistance or aesthetic requirements.
- Ends: Plain ends (square cut) or prepared for welding/threading per customer request.

Benefits to Your Application
- Enhanced Flow Efficiency: The staggered hole pattern minimizes pressure drop while maintaining high filtration accuracy.
- Long Service Life: 316 stainless steel resists pitting, crevice corrosion, and stress cracking, even in aggressive media like seawater or acidic slurries.
- Structural Integrity: Longitudinal seam welding creates a stronger joint compared to spiral welded tubes, making it suitable for load-bearing applications.
- Easy Installation: Precise OD and straightness (±1 mm per 4 m) facilitate quick assembly with existing pipe systems or flanges.
- Customization Options: We offer alternative hole sizes, patterns, end preparations, and surface treatments to match your exact specifications.
Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature for this tube?
A: 316 stainless steel can be used continuously up to 800°C in oxidizing environments, but the actual limit depends on the application. For higher temperatures, consider 310S or Inconel alloys. -
Q: Can you supply tubes with a different hole pattern, such as square or slot holes?
A: Yes, we can produce round, square, or slot perforations. The tooling changeover may require a minimum order quantity. Please contact us with your pattern drawing. -
Q: How is the longitudinal seam weld inspected?
A: Each weld is visually inspected and may be subjected to hydrostatic testing or dye penetrant examination upon request. We follow in-house quality procedures based on industry standards. -
Q: What is the typical lead time for a 4m length tube?
A: For standard sizes, lead time is 15–20 working days after order confirmation. Custom orders may take 25–30 days depending on complexity. -
Q: Do you offer samples before mass production?
A: Yes, we can provide a sample of 200mm length or custom size. Sample cost is deducted from the first order. Shipping is at buyer's expense. -
Q: Is the tube suitable for use in cleanroom or food-grade environments?
A: Yes, with proper surface finish (pickled and passivated) it meets basic hygiene requirements. For food contact, we recommend electropolishing to reduce surface roughness. -
Q: What is the minimum order quantity?
A: Usually 10 pieces for standard sizes. For custom specifications, MOQ may be higher. We welcome small trial orders for new customers.
