Product Features & Technical Specifications: Our helically perforated tube is manufactured from premium-grade 316L stainless steel, known for its excellent resistance to pitting, crevice corrosion, and chemical attack. The unique helical (spiral) perforation pattern ensures even flow distribution, structural integrity, and aesthetic appeal. Below are key specifications:
| Parameter | Available Range |
| Outer Diameter | 10mm – 100mm (customizable) |
| Wall Thickness | 0.5mm – 5.0mm |
| Length | Up to 6 meters (custom lengths available) |
| Hole Shape | Round, square, or custom geometry |
| Perforation Helix Angle | 15° – 45° (adjustable) |
| Open Area Ratio | 10% – 60% (customizable) |
Key Advantages & Customer Benefits:
- Superior Corrosion Resistance: 316L stainless steel contains molybdenum, providing exceptional resistance to chlorides, acids, and harsh chemicals. Ideal for marine, chemical processing, and pharmaceutical applications.
- Helical Design for Uniform Flow: The spiral perforation pattern ensures consistent fluid or gas distribution, reducing turbulence and pressure drop. This is particularly beneficial in filtration, heat exchange, and ventilation systems.
- High Structural Strength: Despite the perforations, the tube maintains excellent mechanical integrity. The helical pattern adds torsional stability, making it suitable for load-bearing applications.
- Customizable Dimensions & Patterns: We offer full customization – outer diameter, wall thickness, length, hole size, pitch, and helix angle can be tailored to your exact specifications. No minimum order quantity restrictions for custom orders.
