Stainless Steel, Aluminum Spiral Welded Pipe Filter For Food Products / Medical Material

Materials: stainless steel, aluminum, or other materials.

It is used directly as filter tubes and cylinders for certain industries.

Micron opening perforated metals are used as filters or screens itself in the screening of coal, gravel and ore; in the shifting and separation of food products and medical material, fine chemicals and oil. Made of quality stainless steel or carbon steel sheets, perforated filter tubes and cylinders can be made spiral welded or butt welded in a wide range of sizes.
 

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.
