In industrial filtration systems, especially in pump suction lines, I often see cone-shaped elements referred to as “ witches hat strainers .” For anyone unfamiliar, a witches hat strainer (also called a cone strainer ) is a conical stainless steel filter installed directly inside a pipeline. It’s typically used as a temporary or compact solution to protect downstream equipment from debris during startup or maintenance operations. Why engineers choose them: Lower pressure drop compared to flat screens Compact installation inside flanges Good debris distribution due to angled geometry Available in mesh, perforated plate, or wedge wire They're commonly used in : • Water treatment systems • Chemical processing lines • Pump protection • Resin retention setups Curious how others approach pre-filtration in tight pipeline layouts — do you prefer cone strainers, basket strainers, or temporary spool strainers?
