free of defects. The pipeline should also be checked for
proper alignment. Strainers should never be utilized to
realign an existing piping system.

3.
Ensure that the pipeline setup allows a horizontal
installation of the basket strainer.
ϰ͘
If pipeline strain is a concern when installing larger
basket strainers (6” and above), a concrete or steel pad
should be used to provide additional support. Larger

reducing strain on the pipeline.
5.
If the basket strainer is to be located on the discharge
side of a pump, then a safety release valve must be
installed between the basket strainer and the pump.
Installation Procedure:
1.
To provide for easier maintenance, the basket strainer
should be located where the drain plug can be removed
and where there is ample space above the basket
strainer for screen removal.
2.
Before placing the basket strainer into place, support
the existing pipeline with pipe supports near the inlet
and outlet connections of the basket strainer.
3.
Place the basket strainer into the pipeline ensuring that

or heavy strainers, lift the basket strainer into place
using slings positioned underneath the inlet and outlet
connections.

Operation
Once proper installation has been successfully completed,
start the system gradually, at start up as well as after shut
down. This eliminates sudden shock to the strainer and
other equipment in the line. This is extremely important for
steam service.
Start-Up Procedure
1.
Remove air from the pipeline by opening the vent near
the basket strainer.

It is important to start the system gradually to avoid
displacing or damaging the basket strainer.
