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.
