Temporary Strainers are generally used at startup of pipe lines to filter larger debris and foreign objects that may be present during construction and startup. They may be conical or truncated. Flow and media determines the direction of the strainer.
Temporary Strainers are used for start-up of new or revamped piping systems. They will prevent construction debris from causing damage to downstream equipment. The screen cone is tig welded around the entire circumference of the flange ring to provide strength and prevent unwanted bypass. Additionally Contact Us for more information.

Conical strainers are perforated devices of perforated or woven mesh to catch particles in a pipeline.
Sometimes, these can be temporary and put in pipelines to protect equipment from debris and particles. Conical strainers are shaped like a cone, or witch’s hat.
Conical strainers can catch particles down to .001 inch in diameter. Cone strainers have little pressure drop, and can be removed after startup, and the debris is evacuated.
The sizing of Conical strainers is important to ensure the strainer screen can block particles that could damage equipment.
