Strong Rewashable Strainers of Pipeline Coarse Filtration
A Perforated filter also named temporary strainer or strainer filter, is made of metal perforated plates and woven mesh that is welded together. They are available in lots of shapes to suit different pipe systems, including perforated basket strainers, perforated conical strainers, and perforated plate strainers. Other different strainer shapes also can be customized upon request.

Basket Strainers
Compared to cone strainers, basket strainers feature a cylinder shape with a flat top and are normally made of woven wire mesh, perforated plates, or a combination of both. It is available in the standard basket, slanted basket, with or without handles.

Cone Strainers
Cone strainers, also known as conicastrainers or hat strainers, are installed in the inlet port of the relief valve, decompression valve, water levevalve, and other equipment.

Plate Strainers
Also known as disc strainers, or plate strainers, it plays an important role to protect downstream equipment during initiastart-up and normaperiods. Although the contact surface of the plate strainer is smaller than the above two types, it is easier to quicker to remove from the two flanges of pipelines.
