metal fittings prone to corrosion

Drinking Water Problems: Corrosion -What levels of corrosion are Chemical processes can slowly dissolve metal causing corrosion. Over time, the water erodes the copper, causing leaks—almost always in angle fittings. manufacturing defects can make copper piping more susceptible to corrosion.

Copper tubing Compression fittings use a soft metal or thermoplastic ring the compression ring, 'olive' or 'ferrule' which is squeezed onto the pipe and into the fitting by a compression nut. The soft metal conforms to the surface of the tubing and the fitting and creates a seal. Compression connections do not typically have the long life that sweat connections offer, but are advantageous in many cases .

Corrosionpedia - 21 Types of Pipe Corrosion and Failure The corrosion of steel piping and its related components is a continuous and virtually unstoppable process. The end product, which is commonly referred to as rust, is simply the result of an electrochemical reaction through which the higher energy-processed metal is slowly reverted back to its naturally occurring form: metal ore.

Galvanic Corrosion: This can occur when two different metals are lo ed together in a liquid electrolyte such as salt water. In essence, one metal& 39;s molecules are dn toward the other metal, leading to corrosion in only one of the two metals.

Cold water pitting of copper tube 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 environment. The corrosion rate of copper in most potable waters is less than 2.5 µm/year, at this rate a 15 .
