Temporary Strainer

A temporary strainer is installed between flanges for the startup phase of a pipeline, then removed once the system is clean. Its job is to catch construction debris — weld slag, mill scale, sand and gasket fragments — before it reaches rotating equipment, control valves or flow meters.

Because the strainer is a temporary item, it is built for easy installation and cleaning rather than long service life: a light stainless body with a removable screen cartridge that can be lifted out, rinsed and refitted within minutes.

• Conical type — a cone-shaped screen fitted between two flanges; large open area, used where line size is fixed.
• Basket type — a cylindrical basket with a handle, easiest to remove and clean.
• Y-type — compact inline body for smaller lines and tighter spaces.
