Gasket Replacement
Gasket and gasket surfaces should be thoroughly cleaned and should be free of scratches and other
defects. Gasket should be properly positioned before attempting to retighten bolts. It is recommended
that when a heavy heat exchanger is dismantled for any purpose, it needs to be reassembled with new
gaskets. This will tend to prevent future leaks and/or damage to the gasket-seating surface of the heat
exchanger. Composition gaskets become dried out and brittle so that they do not always provide an
effective seal when re-used, they may provide an imperfect seal or result in deformation and damage to
the gasket contact surface of the exchanger. Follow industry recognized flange bolt tightening practices.

Cleaning Methods
Provide convenient means for cleaning tube bundle frequently as suggested below:
1
Circulating hot wash oil or light distillate through and over the tube at high velocity will effectively
remove sludge or other similar soft deposits.
2
Circulating hot fresh water may wash out soft salt deposits.
3
Some commercially available cleaning compounds may be used to assist in removing sludge or coke,
provided hot wash oil or water, as described above, does not give satisfactory results.
4
Removal of various scales and foreign material by chemical cleaning is now being quite extensively
practiced. Certain qualified organizations will check the nature of deposits to be removed, furnish
proper acid solutions containing inhibitors, and provide equipment and personnel for a complete
apparatus and piping cleaning job.
5
If none of the above methods are effective for the removal of a hard scale, coke, or other deposits,
mechanical means may be used.
