China PVC-O500 grade water supply pipe

pvc-o pipe is also called biaxially stretched PVC pipe. It is a new type of pressure-bearing pipe obtained by axial and circumferential stretching (biaxial stretching) of traditional PVC-U pipe under high temperature elastic state. The advantage is that through bidirectional stretching of the material, the molecular chain of the material has a linear structure before stretching into a network structure after stretching, which makes PVC-O pipes have higher pressure resistance than traditional PVC-U pipes. It has nearly doubled, and its low-temperature impact resistance and stress crack resistance are 5 times that of PVC-U pipes. It is a new generation of pressure-resistant pipes developed at home and abroad.
