Strainer Questions
Installation posture
- Tell me about the piping posture of a Y-strainer.
-
Install a Y-strainer so that the screen faces downward.
・In the case of horizontal piping, connect the piping so that the cap or cover faces downward as shown in the figure.
・When the fluid is descending in vertical piping, connect the piping so that the cap or cover faces downward as shown in the figure. When the fluid is ascending, provide a horizontal piping section to connect the piping.If the strainer is installed in the reverse position, foreign matter and dust may flow back into the primary piping, so it is not recommended.
Product information
- Tell me the characteristics of a U-strainer.
-
A U-strainer is easy to clean because the screen is removed from above after removing the top cover. Therefore, it can be used in lines where maintenance space is not available with a Y-strainer in floor piping.
However, please note that the installation posture is only for horizontal piping.
Product purchase
- Do you sell the screen of a strainer as a separate part?
-
We sell it as a maintenance part.
Please contact your dealer for the product model, nominal diameter and screen specifications.
Maintenance
- Regarding cleaning of the screen of a strainer, what is the recommended frequency?
-
We recommend cleaning the screen when the differential pressure across the strainer approaches 0.1 MPa.
Screens
- Tell me about the standard screens of the strainers.
-
The standard screens of our strainers are as follows.
* For meshes other than those below, please contact us separately.
- What is the mesh size of a screen?
-
Mesh size means the number of openings between 1 inch (25.4 mm), and the larger the number, the finer the mesh opening.
In the figure below, there are five openings per row between 1 inch (25.4 mm), and it is an image of a screen with a mesh size of 5.
*Actually, there is no specification for a mesh size of 5.
- Tell me the mesh wire diameters and void ratios of the screens.
-
The mesh wire diameters and void ratios are as follows. (Inner mesh dimensions used by us)
