Pressure Pipe System Materials
U-PVC (unplasticized polyvinyl chloride) is one of the most widespread plastic materials to be used in different sectors, this is thanks to its thermal stability, resistance to chemical agents and mechanical durability at high temperatures (up to 60°). Both pressure pipe valves and fittings are products which greatly benefit from the special characteristics of U-PVC. Achieved after the polymerization process of vinyl chloride monomer U-PVC becomes a resistant resin which is odourless and which does not release any particles into a fluid with which the finished pressure pipework products comes into contact.
It is both suited for the management and transport of food liquids and water with both acids and alkalines, hydrocarbons and saline solutions. Thanks to its thermal and mechanical resistance and to its reasonable hardness, U-PVC guarantees reduced dilation levels and a high level of safety and usage duration, ensuring both fittings and valves are long lasting and reliable products over time.
ABS (acrylonitrile butadiene styrene) is a thermoplastic polymeric material whose primary characteristics are lightness and rigidity, extremely important for manufacturing ball valves. It has a special electrical resistance and can be successfully applied to installations subject to temperature changes from -40° to +70°c. This makes ABS pipe system products well suited to applications where temperature extremes are a consideration.
ABS valves and fittings are resistant to some acids and aggressive agents, to mineral oils and fatty substances, in addition to being suitable for use with water and saline solutions.
