3-5 Piping Considerations for High Mobility
Installations
Mobile Economical Series systems must use high quality hose rated for at least 150
psig and 250
°F (1,034.25 kPa/10.34 bars and 121ºC). Special 300°F (149ºC) high
temperature Economical Series systems must use hosing rated at 150 psig and 300
°F
(1,034.25 kPa/10.34 bars and 149ºC) or greater.
Quick disconnects may be used for mobility, although they cause a drop in pressure.
If used, they must be sized carefully to minimize pressure drop. Don’t use quick
disconnects with check valves unless absolutely necessary.
!
CAUTION
Non-relieving quick connect fittings or check valves on the water supply
must have a pressure relief piped to the drain.
Failure to do so could result in a dangerous over-pressure condition!
3-6 Process Water Considerations
Raw Water
Water treatment is vital in any piping system. In some cases, raw water may be used in
the system without problems; in other cases, it can result in large deposits of scale and
corrosion.
We offer a complete line of water treatment equipment. Contact your sales
representative for water testing and treatment options.
Distilled Water
Non-ferrous (brass, copper, or high-temperature plastic) piping is recommended for
distilled water processes.
