Solvay Plumbing: How to Eliminate Corrosion? Just use plastics in water handling applications

[inspic=153,left,,120]Solvay – the international Chemical and Plastic Group – operates in the Plumbing sector with a focused team who provides a wide portfolio of materials to face the needs of a demanding industry. Enclosed please find an article where Solvay talks about Corrosion and how to eliminate it: What are the advantages that have driven plastics to a growing success in pressurized systems for drinking water, heating, and industrial applications? For decades metal has been chosen as the main material for devices in the water industry. The rapid evolution of regulations and new requirements for this market have shown the limits of metals in answering this sector’s needs. Corrosion, heavy metal release, mineral building-up and low thermal insulation are only some of the reasons why metals are outperformed by new high performance plastics. The Solvay Group, one of the world’s leading companies in the production of high-performance polymers, offers four distinct families of plastics for use in water handling applications: cross-linkable polyethylene, fluoropolymers, sulfone polymers, and semi-aromatic polyamides. Thanks to their unique properties mix, they exceed the performance aspects of copper based alloys in pipes, fittings, manifolds, taps and valves in many ways.

One of the main advantages is corrosion resistance: Metals are sensitive to oxidizers. Sodium hypochloride, for example, which is widely used for sanitation of potbable water, can, over time, provoke the formation of rust in stainless steel installations. Oxidizers can also lead to corrosion of copper based alloys. Moreover, the usage of brass fittings in combination with multilayer pipes including an aluminum layer can lead to an electric potential between the aluminum and the brass and subsequent galvanic corrosion of the aluminum.All Solvay plumbing products show an excellent resistance to chemicals and hot chlorinated water. These aspects grant numerous advantages for the manufacturer:
· Possibility for long-term use with common oxidizers
· No risk of contamination by heavy metals, in contrast to metal installations
· High cost-effectiveness due to one step production and low maintenance costs
· Large freedom of design
