Piping Connections
You should properly size all external piping to insure minimal external pressure drop for best
operation.
Note: Always use a backup wrench to support TOH unit piping when making piping
connections. All external piping must be supported independently of the TOH unit.
AEC, Inc. recommends that you have strainers installed on the cooling water inlets.
For service and maintenance reasons, AEC, Inc. recommends that you have customer-supplied
shut-off valves on all piping connections. Use common black welded pipe for permanent
installations.
If you must use a pipe joint compound, use a compound that can withstand the high temperatures
and pressures of your TOH unit. Always insulate all piping to prevent bum hazards and to retain
heat. Make sure insulation is properly rated for maximum operating temperatures of your TOH
unit.
Piping Considerations for Mobile Installations
•
Because your TOH unit is mobile, it is well suited for multiple applications. You can purchase
high-quality hose from AEC/ Application Engineering to enhance the mobility of your TOH unit.
•
We stock many lengths of flexible metal hose to be used in connecting the unit to your process.
State length when ordering.
Although they cause a drop in pressure, you can also install quick disconnects to your TOH unit.
~
Do not install check valves with quick disconnects unless absolutely necessary!
Process Piping Connections
Caution!
•
Hoses, valves and other components in your process must be able to
withstand TOH unit maximum temperatures and pressures.
•
Maximum temperatures and pressures are listed on the unit nameplate.
•
Carefully inspect all components before installation.
•
If in doubt about component suitability, obtain factory components.
•
Fix all leaks! Fluid can be a potential fire and slip hazard.
