Heat transfer plate refurbishment

 

Removal from site

 

Our engineers are available to attend site to open heat exchangers and remove the existing plates and gaskets.

 

Initial inspection

 

When the plates and gaskets arrive back at our works they are checked in against the customers’ specification and visually inspected for any damage.

 

Chemical clean

 

The plates are then degasketed and dipped in a series of chemical baths to remove deposits and scaling. They are then pressure washed and dried before being visually inspected for the second time.

 

Dye penetrant testing

 

The cleaned plates are then sprayed with a fluorescent dye and inspected with an ultra violet lamp for pin holes and cracks.

Plate replacement

A report will be provided detailing any plate failures and recommendations will be made. Failed plates will be replaced with new plates following our customers' instructions.

Quick turnaround

Plates are usually available for despatch approximately 1 week after removal from site

 

Installation

 

If required our engineers are available to return to site to fit the refurbished plates, tighten the heat exchanger to the appropriate dimension and test for leaks.
