We supply perforated tubes to support the filter media in making of various filter elements. Using of perforated metal adds more strength and pressure resistance in filter flow.

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.

Specify the following when you order perforated tubes from us:
Materials: stainless steel, aluminum, or other materials.
Hole pattern: Micron round, diamond and others.
Open area: It will determine the strength of the support tube and the filter flow.
Hole size and thickness: Various to meet different requirements for tubing strength and filtration.

The mostly used stainless steel perforated tubes include 304, 304L, 316, 316L. Carbon steel can also be used.
Hole patterns include round, square, hexagonal, oval and special openings.

The thickness of metal tubes perforated: 0.2mm to 15mm
Opening diameter: 0.2mm to 100mm

Processes involved in making of perforated tubes: Perforating, flattening, rolling, cutting, bending, edging, welding and finishing.http://www.perforated-metal.net
