PVC-O pipes also called biaxial oriented PVC pipes.Under certain conditions of pressure,temperature and speed,by stretching the material in hoop and axial orientation,a higher of can be seen at a glance.The process of molecular orientation greatly enhances PVC's physical and mechanical properties.PVC-O pipes strength 2 times compare with PVC-U,the impact resistance and cold temperature resistance 5 times compare with PVC-U pipe.PVC-O pipes are the most advanced pipes for the conveyance of high-pressure water in the world.
