Frequently asked questions about PVC-U
What is the difference between PVC-U and PVC-C?
PVC-C (chlorinated PVC) withstands higher temperatures (up to ~90 °C instead of ~60 °C) and is even more chemically resistant.
How is PVC jointed?
PVC-U/-C is usually solvent-cemented (cold welding) or flanged – fast and economical.
Is PVC-U suitable for drinking water?
Yes, for pressure pipes per EN ISO 1452 in water supply and irrigation.
Request PVC-U?
Medium, pressure, temperature, size and quantity are enough – we recommend the material and supply the complete system including fittings and welding technology.
