A Study And Simulation Of Flux Induced Corrosion In Copper Tubing Used For The Distribution Of Potable Water, Daniel O. Benham

Materials Engineering

Water side corrosion within copper plumbing can occur due to a wide variety of unwanted circumstances. Through the controlled immersion of six ¾” copper tubing samples with five utilizing a unique industry standard soldering flux, this investigation associates residual flux deposits with the initiation of pitting in copper. Water stagnation in a copper potable water distribution system, typically associated with an infrequently used faucet, is a condition highly prone to copper pitting. A test apparatus designed to produce a partially stagnant flow condition with scheduled electrolyte flushes every 3 days was developed and constructed to contain 6 test samples for ...
