304 Stainless Steel Spiral Welded Pounched Filter Tube

The pounched filter tube is also called spiral steel pipe or spiral welded pipe. It is made by rolling the perforated metal mesh belt into a tube blank at a certain angle of the spiral line (called forming angle), and then welding the pipe joint, which can be used. A narrow strip produces a large diameter steel tube. The perforated metal screen spiral tube can be round, square, diamond or other hole type customized to your requirements. And the stainless steel punching spiral tube is a good filter device.

Perforated Metal Tubes are popularly used in filter products as support tubing, and sometimes it is used directly as filter tubes and cylinders for certain industries.
Material: Stainless Steel, type 304,321,316, 316L and so on.

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.

Spiral welded tubing has been processed by centerless grinding, plating, sand blasting, deburring and buffing. These finishes will make subsequent operations smooth and cost-efficient.

Welded spiral perforated tube is available in various margin and end patterns.
