Pipe corrosion

1. Solution to Pipe Corrosion in the Long-term? "What's the alternative?", found in Consulting-Specifying Engineer, discusses the benefits of plastic piping. In particular, newer types of plastics like CPVC and PEX are the focus. The article is a published transcription of a roundtable discussion. It is well know that corrosion in metal piping causes many economic, environmental, and safety problems. This article proposes that CPVC and PEX are extremely resistant to corrosion and have many other …

…the pipe is preferable. With the development of plastic piping, this is now more possible than ever. Another way to minimize pipeline corrosion is to keep the amount of fittings and especially elbows to a minimum. Inclination of the pipe may also be of concern to prevent standing fluid. In some cases with metal pipes a current can be applied to the metal to prevent electro-chemical reactions. Source: My Materials Science Text (Chapter on Corrosion)
