Customized Hole Punching / Perforated Metal Spiral Welded Pipe For Water Filtration

Spiral welded perforated metal pipe, also can be called punched metal pipe; Perforated metal pipe Materials: Material is 304, 316 stainless steel, carbon steel and iron. Manufacturing processes: hole punching – cut the steel plate - vol round - polishing. Welding methods: Spiral welding, straight welding Application: Used For water filtration and environmental protection industries Hole size and shape can be customized according to customers\' requirements. Packaging Detail: We can pack as clients’ requirement.

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.
