Strainers, screens, and filters are used in plumbing as fittings for filtering, purification, and separation of liquid from solids such as scales, rust, and welded metal pieces. They can be made of materials like cast iron, bronze, carbon steel, chrome-moly steel, stainless steel and high-grade plastics such as polypropylene. They are designed to be durable and with little maintenance requirements. Strainers consist of perforated or mesh screens and are usually placed in upstream locations to protect critical downstream equipment, including control valves, pumps, steam pumps, and flow meters. The two types of strainers are Y-Type Strainers and T-Type or Basket Type strainers. Filters are devices that separate particles from liquids and gases. They constitute disposable components that are capable of filtering micro-sized impurities. All strainers are special function filters that can be re-used. Screen filters are used to filter water, and they feature flexible or rigid screens that are used to separate fine particles such as sand from water.
