Spiral Welding Perforated Tube is widely used in many fields, which is a filter product with the sane the perforated round hole tube. Our factory provides a variety of tube diameter and hole size for customizing types. It is produced using helically forming and automatically welded continuous strip of stainless steel or mild steel. This method of production based on high precision and quality of welding allows manufacturing tube of exacting diameters in a practically unlimited variable range of sizes.

Spiral Perforated Tube also named Spiral Welding Perforated Tube，Spiral Perforated pipe, perforated spiral welding pipe, spiral welding perforated pipe, spiral welding perforated tube.

Spiral welded perforated tube materials: stainless steel 304, 316, 316 L, carbon steel, aluminium, copper and other metal plate

The tube Specifications:

The diameter: 25-1000mm

The thickness: 0.8-12mm

The length: less than 12m

The hole type: bridge hole, round hole ,square hole and so on.

The specifications and materials of hole punching can be produced and installed in accordance with the needs of users.

Features:

5. Spiral welded perforated tube is approximately 15% stronger than longitudinally and welded tube

6. Easy for installation and less work time

7. Unlimited tube lengths

8. Lighter wall thickness can be used

Applications: Spiral welded perforated tube is used for petroleum, oil extraction, chemical, sewage treatment equipment, filter impurities in water purification.

Spiral Welding Perforated Tube production process:

• the first will be punching mesh belt according to customer requirements
• after the punching will mesh belt by the spiral bending forming, argon arc welding.
• Surface treatment: mild steel to prevent corrosion, oil or to oil, sand blasting processing. Pickling or shield, stainless steel electrolytic polishing, surface coating, epoxy coating, or other etc.

Spiral Welding Perforated Metal Tube Quality control:

Raw material inspection-punching - roll welding inspection straightness, roundness inspection - cutting - pickling, shield inspection - finished products.
