Dissimilar Metals in Heating and AC Piping Systems
Joining two metals together may cause accelerated corrosion, however, using different metals in a piping system does not always cause a failure. This article presents guidance on what to do when different metals are used in heating and air-conditioning piping systems, the factors involved when corrosion occurs, and offers practical solutions on how to avoid it.
