7. Installation
During the installation of the strainer the following steps should be observed:
・
Visually inspect the strainer initially to ensure it is undamaged and also ensure that
it is suited to the medium and working conditions used in the plant.
・
Remove dust caps if supplied.
・
Check that the strainer body is free of solid particles.
・
Steam pipelines should be fitted in such a way as to avoid condensate collection;
in order to avoid water hammer, a steam trap should be installed.
・
Protect the strainer during installation from debris and excessive temperature
conditions.
The pipeline where the strainer is fitted should be arranged in such a way that
the strainer body is not subjected to any bending or stretching forces.
Bolted joints on the pipeline must not cause additional stress resulting from
excessive tightening, and fastener materials must comply with the working
conditions of the plant.
Install the strainer in such a way that flow direction matches that of the arrow
placed on the body.
・
The strainer body throat with screen should be positioned downwards in order to
allow any sludge to collect there.
・
If there is a risk of water hammer caused by condensate
formation, the strainer body throat should be installed in
the horizontal position.
・
The plant designer should ensure space to take the screen out of the strainer body
for cleaning.
・
Use expansion pipe joints to reduce the influence of pipeline thermal expansion.
・
Flush out the pipeline before plant startup, especially after repairs are carried out.
