Before installing the piping to the heat exchanger, inspect all the ports for foreign debris that
could become lodged during operation.
All connections to the heat exchanger must be
provided with shut-off valves (F2,F3,M2,M3). The
upper connections must be provided with venting
devices at their highest points. The hot side re-
gulating valve must be installed in the feed pipe
between the pump and the shut off valve.
To prevent water hammer in the heat exchanger,
quick action valves should not be used.
Provide safety relief valves where the maximum
discharge pressure of the pump can exceed the
design pressure of the heat exchanger.
When the plate heat exchanger is installed in a situation having zero tolerance for process fluids
being on the floor, a liquid retaining drip pan with a volume capacity equal to the heat exchanger
shall be mounted under the plate pack to catch and control any leaking fluids.
Pumps should have throttling valves and vibration dampers shall be used on positive displace-
ment pumps and especially reviprocating pumps.
For care free and dependable operation of the heat exchanger, avoid sudden pressure and/or
temperature surges.
3.2 Piping
The piping connected to the heat exchanger shall be designed and built so that it’s thermal expan-
sion and weight do not apply any force to the heat exchanger’s nozzle causing premature failure.
Any forces or moments applied to the connections of the heat exchanger must be approved by
