Strainer Screen Data

MAGNETIC INSERTS

Magnetic inserts may be furnished, which when placed inside the strainer screen or basket, will collect very fine ferrous metal particles entrained in the liquid thus protecting equipment against abrasive damage.

Common Perforations And Mesh Open Areas

Our strainer screens are made in a variety of perforations and mesh openings to best suit the application. Standard material is 304 stainless steel. Other screen materials are available on special request. When screens are constructed of very fine mesh wire cloth, they are reinforced with a rigid outer shell of perforated sheet. Perforated screens are made of sheet stainless steel, the thickness of which is not greater than half the size of the perforations.

OPENING RATIOS

The following steps should be taken to determine the ratio of openings through strainer screens to the area of inlet pipe size.

1. Determine the size mesh or perforation required to give the desired particle retention.

2. Multiply the total area of the screen by the percent of open area of the perforation or mesh material. The result is the open area of the screen. (Total area of the screen is given in the dimensional charts).

3. The open area of the screen divided by the area of the pipe will give the ratio of open area of the screen to the area of the pipe.

4. To determine the ratio of open area to the pipe on mesh lined reinforced screens, complete step two (2) to find the open area of the mesh. Multiply the open area of the mesh by the percent of open area of the reinforcing material. The result divided by the area of the pipe will be the ratio of open area of the screen to the area of the pipe.
