Please refer to the table.
Strainer shared screen reference table
Y-type strainer: compact type with low fluid resistance and small installation space
U-type strainer: bucket-shaped screen with a handle, having a larger filtration area than Y-type
W-type strainer: duplex type whose flow path can be switched and screen can be cleaned without stopping the flow
Temporary strainer: for pipe flushing before starting operation
It is possible for steel type strainer such as SY-13 or SU-6.
Please contact us with the Munsell color number. We will review and reply.
Reinforcement of the screen or replacement with different type of screen can be measures. Please contact us.
Install pressure gauges before and after the strainer and use the strainer within 0.1 MPa of differential pressure. When differential pressure approaches to 0.1 MPa, clean the screen (mesh).
Horizontal piping is necessary on steam line to prevent condensate retention or freezing.
Select a strainer with the same size as the nominal size of piping. According to fluid type, select Y-type, U-type, straight type strainer.
If there is few space downward of the strainer for water, we recommend ST-10 since cleaning or replacement of screen (mesh) can be performed without tools.
Reverse washing is to wash a strainer by flowing fluid in the reverse direction in order to remove scales.?Install a bypass pipe and a blow valve around the strainer. The reverse washing should be applied only to single-layered screens. If this is applied to a double screen (perforated metal + mesh) the internal mesh may be torn off from the screen and damaged.
"Perforation" refers to holes on the outer metal sheet of the screen and indicated by the hole size and the pitch.
"Mesh" refers to the wire mesh inside the screen and indicated by the mesh size. Mesh size is a unit to show how fine the mesh is. It shows the number of openings per inch (25.4mm).
[Example: if there are 20 openings, the mesh is referred to as 20 mesh.]
Followings are standards mentioned by public organizations in Japan.
1. Construction standard specifications (for the construction of machinery and equipment), issued by Public Buildings Association
* 40mesh or more for water (80mesh or more when installed before a solenoid valve), 80mesh or more for steam
2. The common specifications for the construction of public housing, issued by the housing bureau, Ministry of Land, Infrastructure and Transport
* When a strainer is installed before solenoid valve, motor valve and a self actuated valve, the mesh size should be 80 or more.
Available only for the standard mesh of each model.
U-type strainers are for liquid. For gas (including steam), Y-type strainers are recommended.
No, the model has allowable leakage.
Yes, but please install a blow valve to drain scale accumulating on the bottom of the rizer pipe.
Please replace with the new gasket to prevent external leakage.
20 to 100 mesh are available (120 to 200mesh for SY-37 and SY-38). Please contact us for screens with perforation only. Refer to the list of screen.
Please select depending on the mesh size: SY-37 for 120mesh or finer.
Please check the shape (Y or U type), connection, face-to-face dimensions and body material of the strainer and contact us.
Refer to pressure loss chart of each model.
