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.
