Heat Exchanger Leak Detection / Plate Dye-Testing

100% Dye-Testing

WCR 100% Dye-Testing is our standard for locating cracks, pinholes, or failures.  With proprietary red dye-penetrant saturating the plate surface, and white developer solution covering the reverse side, WCR is capable of detecting even miniscule imperfections.  We  test 100% of the plates that come in for service, most competitors only test a percentage. Consider that 90% of plates tested have a 10% fail rate.  Basically, random checking of 10-20% cannot eliminate all bad plates, which WCR guarantees prior to leaving our facility.  Although Dye-Testing is the most time consuming and expensive method for leak detection, WCR chooses the process for its reliability and effectiveness.  Early discovery of plate defects alleviates cross-contamination concerns, saving costly down-time in the future.  

Other Non Destructive Testing Methods for Leak Detection Occassionally Employed by WCR

Ultraviolet Testing

The ultraviolet test is used upon request, usually specialty applications where fluid mediums can only detected under UV light.  The plates is sprayed with a one side of the plate is sprayed with a unique dye-penetrant, then subsequently inspected under UV light, to reveal cracks, pinholes, or failures.

Vacuum Testing

Vacuum testing of plates is used for welded and semi-welded heat exchangers plates. Dye penetrant methods cannot be used with these plate types. This method will detect if a plate has a leak, however, it will not identify the location of the failure.
