2. Erosion corrosion of copper water tubes - Wikipedia

   en.wikipedia.org/wiki/Erosion_corrosion_of...

   Erosion corrosion, also known as impingement damage, is the combined effect of corrosion and erosion caused by rapid flowing turbulent water.It is probably the second most common cause of copper tube failures behind Type 1 pitting which is also known as Cold Water Pitting of Copper Tube.

3. Heat trap - Wikipedia

   en.wikipedia.org/wiki/Heat_trap

   Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water to flow out of the tank. [1] [2] Newer water heaters have built-in heat traps.

4. Cold water pitting of copper tube - Wikipedia

   en.wikipedia.org/wiki/Cold_water_pitting_of...

   Copper tubes have been used to distribute potable water within building for many years and hundreds of miles are installed throughout Europe every year. The long life of copper when exposed to natural waters is a result of its thermodynamic stability, its high resistance to reacting with the environment, and the formation of insoluble corrosion products that insulate the metal from the ...

5. Anodic protection - Wikipedia

   en.wikipedia.org/wiki/Anodic_protection

   Anodic protection (AP) otherwise referred to as Anodic Control is a technique to control the corrosion of a metal surface by making it the anode of an electrochemical cell and controlling the electrode potential in a zone where the metal is passive.

6. Pitting corrosion - Wikipedia

   en.wikipedia.org/wiki/Pitting_corrosion

   Severe pitting corrosion problems caused by chloride ions on a truss beam of the Nandu River Iron Bridge (Hainan Province, China) leading to the complete rupture of a metallic element. Pitting corrosion , or pitting , is a form of extremely localized corrosion that leads to the random creation of small holes in metal.

7. Galvanic corrosion - Wikipedia

   en.wikipedia.org/wiki/Galvanic_corrosion

   Another example is the cathodic protection of buried or submerged structures as well as hot water storage tanks. In this case, sacrificial anodes work as part of a galvanic couple, promoting corrosion of the anode, while protecting the cathode metal.
