Inspection and Refurbishment Process for Plate Heat Exchangers
Inspection of PHE:
Inspect the frame for rust, foundation issues, and general condition.
Check the PHE for side leakages and misalignment in the honeycomb pattern.
Identify and inspect plates for damage.
Plate Identification and Logging:
Upon arrival for refurbishment, plates are identified and logged.
Gaskets are carefully removed from the plates.
Dismantling of PHE:
Dismantle the PHE carefully to avoid damaging the threads on studs or affecting rollers.
Inspect the frame plate (front plate) and pressure plate (back plate) for any damage.
Check stainless steel liners at the inlet and outlet of the PHE frame.
Chemical Cleaning:
Test the soil on the plates and identify the suitable descaling solution.
Soak plates in a descaling solution bath.
Clean with a soap solution and perform chemical cleaning.
Rinse the plates with water, use high-pressure jet wash, and dry thoroughly.
Frame Cleaning:
Wash the frames thoroughly, including the frame plate (front plate) and pressure plate (back plate).
Clean the inner sides of these frames.
Visual Inspection & Dye Penetrant Testing:
Inspect each heat transfer plate visually for cracks, dents, or pinholes.
Apply red dye penetrant on one side and white developer on the other side to detect defects.
Mark any pinholes found and rinse the plates with water.
Gasket – Plate Assembly & Plate Pack :
After Inspection & identification of rejected HT Plates, Acceptable plates are taken for re-gasketing.
Following inspection, new gaskets are clipped or bonded to the refurbished plates.
Appropriate adhesives are used where required.
All plates are clamped to ensure correct alignment.
Plates are arranged as per Flow pass arrangement ensuring Honey Comb Pattern
Complete pack of all the plates as per design is prepared ensuring all channel flow, passes & Honey comb pattern.
Light Box Testing
Testing the HT Plates in dark room with a UV light on another side of the Plate
This visualizes smallest pin hole or crack.
Light box testing is cost effective method of identifying damaged HT Plates.
Assembly of PHE
Plate Pack is inserted between Frame Plate (Front Plate) & Pressure Plate (Back Plate)
Tightening of Studs is been carried out carefully ensuring cross tightening.
Pack length of PHE is been maintained.
Hydrostatic Testing of PHE
After Assembly of PHE, again visual Inspection is done for ensuring fitment
PHE has been performed pressure-leak test before taking for operation.
In case of hydrostatic test, Pressurize hot and cold side independently and/or both sides at the same time.
Actual test pressure shall not exceed the specified test pressure.
Over test pressure could result in heat transfer plate/frame deformation and/or leaking.
The test pressure is referred to Plate Arrangement Drawing.
Inspection Report & PHE Handover
After successful Hydrostatic testing of PHE, Inspection report is prepared for all the activities carried out & replacement of spares, rejection of plates etc.
Inspection report & PHE testing approval is taken from customer before handover of PHE
After confirmation & satisfaction, PHE is handed over to customer.
