Flat Disc Type Temporary Strainer
Flat Disc Type strainers look like a tennis bat and comprises a flat disc, which incorporates a perforated hole section covering the pipe bore area. Although not advisable, meshes are sometimes added to one side facing the flow for finer straining. To identify and assist handling, a handle is provided onto which is normally stamped the size and rating of the flange and the strainer retention.
