PVC piping systems have been used widely for many years in industrial applications for everything from process cooling water to the transport of hazardous chemicals, due to the high corrosion resistance of PVC. The harsh environment within chemical plants and the conveyance of chemicals places high demands on the piping systems in terms of safety, economic factors and subsequent maintenance, which PVC can meet. Piping systems for industry are typically made of chlorinated PVC (C-PVC) due to the material's functional properties that allow high temparatures and increased resistance to corrosion from chemicals.
