All information in this manual is for

CAUTION
The weight of all piping must be
properly supported. Failure to support
piping may result in equipment
damage and/or system leakage.
Piping must take into consideration
potential for freezing interference and/
or damage as a result of expansion,
contraction, vibration, or other
movements.
Dirt, water, and/or other debris in the
piping system after welding may result
in equipment failure.
NOTE:

Typical gaskets used by Fulton include JM Clipper Elastograph gaskets and
Flexitallic gaskets. Adhere to installation instructions and torque requirements for
these gaskets.
15. Install high point bleeds at all high points in the system piping. 1/2” x 12”
nipples welded in the top of the piping with ball valves and plugs attached
are to be used.
NOTE:  It will save a considerable amount of time during the cold fi ltration if the
system piping is cleaned prior to assembly. The mill scale (the results of oxidation)
on the inside of the piping as well as construction debris can foul the fl uid and
cause the need for the fi lters (strainers) to be cleaned more than need be. This can
range from simply using a rag to ordering pickled pipe. (“Pickling” is a process
where the piping is fi rst soaked in an acid bath, then soaked in a neutralizing bath,
then given a protective oil coating.)
16. Install all pipes with a pitch to facilitate draining and venting.
