LEAKS

To locate ruptured or corroded tubes or leaking joints between tubes and tubesheet, the fol-

lowing procedure is recommended:

Drain the heat exchanger completely of any fluid or moisture.

Pressurize the shell side of the unit with fluid (e.g. water, glycol, etc.)

Observe the tube joints and tube ends for indication of test fluid leakage

IX. STORAGE & TRANSPORTATION

During transportation of the heat exchangers, ensure that they are not exposed to mechanical

damages. Upon receipt of the heat exchanger, inspect the unit for shipping damages. Notify the

carrier or the sales office immediately in the event that such damages do occur.

Heat exchangers should be stored in a clean, dry, low humidity area away from corrosive envi-

ronments or weather elements (e.g. rain, snow, blowing dust). If the unit is not to be placed in

immediate service, take precautions to prevent rusting or contamination. Heat exchangers that

are out of service for extended periods of time should be protected against corrosion.

CLEANING:

Shell and tube bundle should be flushed out

periodically. If cleaning is necessary, remove

head and bundle to clean inside of shell and

outside of tubes. Replace gaskets if nec essary.

If unit is installed in a hard water area, inside

of tubing can be cleaned as follows:

Break water connections and plug bot-

tom opening.

Fill the tubes wth a solution of 1 part

muriatic acid to 1 O parts of water

and allow to stand for 2 hours:

CAUTION: A longer period may cause

damage to the copper tubing.

Drain off and flush thoroughly wth

clean water.

Re-assemble unit.

Note:

Commercially available cleaners may also be

used.
