ASTM Spiral Perforated Tube Galvanized Steel Round Hole Welded Seam Durable

Perforated seam is welded in straight line; with unique spiral distribution formed by spiral welding and greater filter strength. When squeezed in some parts from external, under outside pressure, the forced part will have reduced or closed gap and ensures the reliability of sand control. Made with sophisticated technology, stainless steel filter glove has openings in the side with reduced direct corrosion to the perforated welded sand pipe. Seam gap in the processing ranges between 20 mm-0.7mm. The uniform opening ensures the processing difference is within the error scope allowed - 0.015 mm, also ensures the accuracy of its filter requirements. Using high precision perforating technology, the effective slotting length is the three to five times of common cut seam tube and two to three times of common perforated seam tubes.

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.
