PVC-O pipe introduction
PVC-O, Chinese name biaxially oriented PVC, PVC pipe is the latest evolutionary form. The PVC-U pipe produced by the extrusion method is subjected to axial stretching and radial stretching through a pipe made of a special orientation process, so that the PVC long chain molecules in the pipe are arranged in a biaxial direction. Get high strength, high toughness, high impact, anti-fatigue of the new PVC pipe.
Application and Popularization of PVC-O Tube
PVC-O pipe in a substantial increase in the overall performance of the pipe at the same time, but also substantial savings in the use of raw materials, is worthy of the name of the environmental protection and energy saving high-tech new products to promote China's plastic pipe industry upgrading and development plays an important role.
PVC-O pipe with its unique performance advantages can fully meet the urban water supply, fire, farmland water conservancy, rural people drink, water-saving irrigation, industrial and mining enterprises and other areas of water supply requirements. Has a broad development prospects.
PVC-O pipe performance
* Density: PVC-O is basically the same as PVC-U.
* Tensile properties: Axial growth of about 28%; ring growth of about 55%.
* Impact energy: increased by about 400%. (Drop hammer impact test PVC-U 64Nm, 80Nm damage; and PVC-O up to 300Nm).
* Ring stiffness: ≥4KPa.
* Bending performance: similar to PE, far more than PVC-U, anti-foundation settlement capacity enhancement.
* Low temperature performance: -20 ℃ below the pipe still has a very good toughness.
* Resistance to point load performance: multi-layer network structure can effectively prevent the damage to the point load, the requirements of the backfill material greatly reduced.
* Notch effect: does not like PVC-U as a linear cracking phenomenon, the energy will be transmitted to both sides, inhibit cracking.
