Initially, our team of highly trained experts will carefully dislodge each component of the plate heat exchanger and scrutinize all aspects of each component. Based on deformation, pin holes, corrosion, and cracks each inspected component will be evaluated to decide if reconditioning is needed.

The existing gasket will be carefully examined and documented to conclude if the entire gasket should be replaced.

It is common for the plates in the heat exchanger to have loose scaling and fouling hence why our team of experts will ensure the plates are completely cleaned. The cleaning process will vary depending on the level of cleaning required. Different techniques (See Heat Exchanger Cleaning) will be adapted on a case by case basis.

In order to completely eliminate the risk of cross contamination, plates are subjected to the Dye-Penetrant Testing thereby ensuring there are no plates with cracks or pin holes.

Before applying new gaskets it is mandatory to thoroughly prep the gasket groove to ensure no glue residue is left over. Our team of experts will ensure such glue is completely removed, as otherwise it will considerably reduce operational lifetime and make it impossible to adhere the new gasket. One of the major reasons for costly downtime of operations is when the plates have not been sealed correctly. This is mostly a result of a rolled groove and at WCHE it will be identified and addressed in the initial stages; preventing leakages and costly downtime.

Our team of experts at WCHE understand the extreme vitality of correct gasket application during the regasketing process. Improper adhesive of the gasket can cause non-conformance, reduce gasket lifetime, cause corrosion or cracking on the plates during assembly. It is extremely critical that superior bonding adhesive is utilized in the regasketing process. The type of adhesive used may vary based on the application and operating conditions of the heat exchanger, the temperatures and pressures are also taken into consideration.

WCHE offers epoxy heat-curing gasket application as an alternative to traditional adhesive-glued gasket methods. This type of adhesive is recommended for high-pressure units.

All plates from WCHE are carefully scrutinized to perfection to ensure that each and every plate is gasketed straight, free from deformation or excess adhesive, is solidly bonded and in the correct plate pack sequence. In order for quick and easy installation, all the plate packs will be returned in assembling order when the drawing is provided.
