Stainless Steel Spiral Welded Pipe Stainless Steel Perforated Filter Tube specification:

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.

Forward Filter is a factory with more than 10 years’ experience producing Stainless Steel Spiral Welded Perforated Tube in Petrolium Filtration with High Pressure. Our material is higher quality than normal level of other factories and we offered many big brand machinery companies in our domestic market and abroad market

Stainless Steel Spiral Welded Perforated Tube is applied in many industries area like petroleum refining filtration or oil producing filtration, hydraulic filtration, food filtration producing, drainage system, Light decoration, Vehicle Exhausts or Acoustical Dampening products.

Besides Stainless steel, we also can use other materials like galvanized steel , carbon steel and other alloy.

Perforation hole pattern is variety, which can be round, square and blinds

As for the seam style, we usually use spiral formed, if you have more than one hundred thousand meters require, we can accept custom-made.
