SIFFO PVC-O (Oriented Unplasticized Polyvinyl Chloride) pipe represents a revolutionary advancement in pressure piping systems, combining superior strength, durability and cost-effectiveness. PVC-O pipe is also known as dual axis oriented PVC pipe. The higher tensile strength is immediately apparent by stretching the material hoop and axially under specific conditions of pressure, temperature and velocity. The molecular orientation process greatly enhances the physical and mechanical properties of PVC. PVC-O pipe is twice as strong as PVC-U pipe and five times more impact and cold resistant than PVC-U pipe. SIFFO PVC-O pipe outperforms traditional pipe materials in critical applications such as drinking water distribution, irrigation and industrial fluid transfer.
