4.3 Installation Conditions & Environment
4.3.1 WORKING PRESSURE
The design pressure of this product is 15 bar for oil side and
10 bar for water side. Ensure that the working pressure and
surge pressure do not exceed 22 bar for oil side and 15 bar
for water side, and check the working pressure of your system
prior to use.
4.3.2 WORKING TEMPERATURE
Working temperature range: 0°C to 100°C.
Prevent the Shell and Tube from bursting in winter by draining
the cooling water in the cooler when stopping the system
temporarily. (See Cooler draining on Page 7).
4.3.3 INSTALLATION ENvIRONMENT
Use cooling water in accordance with annex WATER QUALITY
CRITERIA AND STANDARDS. Installation in hot and humid
places may cause rust on the external surface. Prevent rusting
by using paint and/or other protective measures.
4.3.4 INSTALLATION PLANNING
1.
On removable bundle heat exchangers provide sufficient
clearance at the stationary end to permit the removal of
the tube bundle from the shell. On the floating head end,
provide space to permit removal of the shell cover and
floating head cover.
2.
Provide valves and bypasses in the piping system so
that both the shell side and tube side may be bypassed
to permit isolation of the heat exchanger for inspection,
cleaning and repairs.
3.
Provide thermometer wells and pressure gauge Pipe
taps in all piping to and from the Heat exchanger, located
as close to the heat exchange as possible.
4.
Provide necessary air vent valves for the heat exchanger
so that it can be purged to prevent or relieve vapor or
gas binding on either the tube side or shell side.
5.
Provide adequate supports for mounting the heat
exchanger so that it will not settle and cause piping
strains. Foundation bolts should be set accurately.
6.
Proper liquid level controls and relief valves and liquid
level and temperature alarms, etc, should be installed.
4.3.5 INSTALLATION AT JOBSITE
Dress properly for the job. You may need any number
of special items (safety hat, safety shoes, goggles,
heavy gloves, ear protective devices, etc, for your
own protection). Find out what items are required and
wear them!
1.
On receipt of the heat exchanger at the jobsite, inspect
for shipping damage to all protective covers. If damage is
evident, inspect for possible contamination and replace
protective covers if required. If damage is extensive,
notify the carrier immediatly.
2.
Store under cover in heated aread, if possible.
3.
If the heat exchanger must be stored for a period
exceeding 30 days, pre-cautions should be taken to
prevent rusting or contamination. Following extended
storage, it is suggested that the exchanger be thoroughly
inspected prior to installation.
4.
When installing, set heat exchanger so that pipe
connections can be made without forcing.
5.
Before piping up, inspect all opening in the heat
exchanger for foreign material. Remove all plastic
protections immediately prior to installing. Do not
expose internal passages of the heat exchanger to the
atmosphere since moisture or harmful contaminants may
enter the unit.
6.
Connect the shell and tube cooler to the
hydraulic system.
