Perforated Tube Spiral Welded is manufactured from quality perforated metal via superior technology in spiral welding, used as Filter Core in a variety of filtration systems. Spiral welded filter cores are mainly used in industries such as water treatment, pharmaceuticals, petrochemicals, and food and beverage. Stainless and steel perforated spiral wound welded tubes provide the structural support for filter media, enabling effective fluid passage while trapping particulates.
We supply a diverse range of perforated metal filter cores to meet varying filtration systems.
Common lengths available: 9-7/8", 10, 19.5, 20, 30, and 40 inches.
