Alfa Laval Compabloc Plate Heat Exchanger CPF15

Ensure all original components are reassembled

Verify the following components are fully tightened

Enter the design pressure indicated on the nameplate

Is the first circuit empty and the second circuit full and pressurized at design pressure?

Is the maximum allowed differential pressure not exceeded during the test?

Pressurize the second circuit to secure the differential pressure

Wait for 30 minutes for pressure stabilization

Ensure chemical cleaning is carried out by authorized and qualified personnel.

Take all necessary protection and precautions for health, safety, and environment regarding chemicals.

Ensure compatibility of cleaning agents with materials of construction such as metal and gaskets.

Select the type of deposit and corresponding cleaning agent

Check suitability of cleaning protocol with materials of the Compabloc.

Is the cleaning protocol compatible with the materials of construction?

Ensure not to use hydrochloric acid or substances containing chlorides.

Supervision of Key Process Parameters

Record the temperature of the heat exchanger

Record the pressure drop across the heat exchanger

Is there any contamination of media observed?

If contamination is observed, describe the analysis for internal leakage

Is there a variation in pressure drop indicating performance loss?

Is cleaning of the heat exchanger required to remove fouling?

Dismantling Procedure for Panels

Progressively loosen the nuts one girder after the other

Loosen bottom nuts one panel after the other

Do not unscrew stud bolts or nuts for girder assembly to top and bottom heads

Remove panels starting with the highest weight and finish with the lowest weight

Use welded or screwed lifting lugs to lift panels safely

Clean gasket seating surface thoroughly without scratching

Check external elements of the heat exchanger

Inspect all welds for cracks, defects, and corrosion

Check painting for local absence of coating and blistering

Proceed with internal examination?

Estimate condition of internal elements
