STRAINER INSTALLATION INSTRUCTIONS
A . Ensure all machined surfaces are free of defects and that the
inside of the
strainer is free of foreign objects.
B . For horizontal pipelines, the strainer should be installed so
that the drain
connection is pointed downwards.
C . For flanged end strainers, the flange bolting should be
tightened gradually in
a back and forth clockwise motion.
D . Once installed, increase line pressure gradually and check for
leakage around joints
E . If the strainer is supplied with a start-up screen, monitor
pressure drop carefully.
Brief introduction:
The strainer may be used on all types of pipelines to collect granulated foreign substances and
contaminants collected. It can improve the clearance in the medium, and prolong the life of valves
and other equipments. It is suitable for wafer, petroleum and steam.
