Selection of nominal size
The nominal size of the strainer should be the same as that for the piping. (Nominal size of piping
＝
Nominal size of strainer). Please note that if the nominal size of the strainer is smaller than that for the
piping, the pressure loss of the strainer may grow, resulting in failure to maintain the required pressure
at the inlet of the strainer.
（
See Fig.3: Loss of Pressure.
）
The Japan Industrial Standards (JIS) designates the standard flow velocity for piping by type and
features of the fluid and pipe size. Please refer to this in selecting the appropriate nominal size of the
strainer.
