Applications: Perforated metal sheets are cut and welded into tubes. Widely used in the core of filter or the surface of the pleated filter elements, filter screen, strainers.

Thickness or Gauge of Stainless steel Perforated Tube:Thickness of the metal sheets do not change during the perforation. Normally thickness is expressed in gauge, please see the picture. However, to avoid possible misunderstanding, we would suggest to express them in inches or millimeters.

Diameter and Length of Stainless steel perforated metal tube
Diameter:10mm,15mm,20mm,25mm,30mm,35mm,500mm,etc
Length: 50mm,100mm,200mm,500mm,1200mm, or custom

Margins of Stainless steel perforated tube: Margins are the blank (un-perforated) area along the edges of the sheet. Normally the margin on the length are 20mm minimum, and margin along the width can be 0 minimum, or at clients' requests.

Perforated Tube Cores for Wound Filters

Perforated metal filter element cores are used in various filtration applications, particularly in liquid filtration systems. These cores typically consist of a perforated metal tube around which a filtering material (often a wound wire or a yarn-like material) is wound. The perforated core serves as the structural backbone for the wound material and also facilitates the flow of liquid through the filter.

Features of perforated metal filter cores for wound filters:

  1. High Strength: The metal core provides mechanical strength, enabling the filter to withstand high pressure and mechanical stress.

  2. Flow Rate: The perforation pattern can be designed to facilitate desired flow rates.

  3. Compatibility: Made from materials like stainless steel, these cores are compatible with a wide range of chemicals and temperatures.

  4. Reusability: The metal core can often be reused after cleaning, making it a more sustainable option compared to disposable filters.

  5. Customization: The size, shape, and perforation pattern can be customized according to application requirements.
