We can perform full inspections of your Plate Heat Exchanger, our inspection services can include the following:
Visual Inspection
The first step in inspecting PHE gaskets is a visual examination. This involves checking for any visible signs of wear, tear, or damage. Look for cracks, cuts, or deformations in the gasket material. Any discoloration or swelling can indicate chemical degradation or contamination. Additionally, inspect the gasket seating surfaces on the plates for any signs of corrosion or pitting, which can affect the sealing integrity.
Leak Testing
Leak testing is a critical part of the inspection process. This can be done using various methods, such as pressure testing or dye testing. Pressure testing involves applying a controlled pressure to the system and monitoring for any pressure drops, which could indicate a leak. Dye testing involves injecting a colored dye into the system and checking for any dye leakage around the gaskets.
Operational Performance
Monitoring the operational performance of the PHE can also provide insights into the condition of the gaskets. Unexplained drops in heat transfer efficiency, increased pressure drops, or fluid leakage are all signs that the gaskets may need inspection or replacement. Regularly checking the temperature and pressure readings can help identify potential issues early.
Ultrasonic Testing
For a more detailed inspection, ultrasonic testing can be used. This non-destructive testing method uses high-frequency sound waves to detect internal flaws or defects in the gaskets. Ultrasonic testing can identify issues that are not visible to the naked eye, such as delamination or internal cracks.
