Pipes made of PVC-O are especially advantageous when it comes to hydraulic capacity, ductility, crack propagation and impact and fatigue resistance. This means that PVC-O is an excellent choice for pressure pipes for drinking water. PVC-O is also well suited for buried non-potable applications such as irrigation and sewer pumping mains.
