NEWS ARTICLE ARCHIVESOriented PVC Pressure Pipes Melbourne from VinidexVinidex proudly offers it's cliental the Vinidex Supermain® Oriented PVC pressure pipe. The Oriented PVC Pressure Pipe is the most advanced PVC pipe available and is ideally suited for general water supply, rising mains and other pressure applications. The benefits of PVC pressure pipes have been well established over their long service history. Molecular orientation further enhances the mechanical properties of PVC, allowing energy efficient production whilst conferring considerable performance advantages. These environmental and engineering advantages mean Supermain® is the high-performance, cost-effective pipe material choice for pressure applications. Supermain® is manufactured in a two stage process that comprises the initial extrusion of a feedstock pipe followed by an expansion process that results in bi-axial molecular orientation of the material. The random long chain molecules of PVC become preferentially aligned in the expansion or hoop direction and a marked increase in strength is attained in this direction. For pipes, hoop strength is the primary factor determining resistance to internal pressure. The sketches below illustrate the general principle of orientation. Benefits
