Best Foam Core Pipe - Ajay Pipes



What is a foam core pipe and how is it different from a regular pipe ? This is the first question that comes to mind when thinking of installing a new underground drainage system and selecting the right pipes for it.
Foam Core pipes are manufactured using the latest tri-extrusion techniques which produces a three layer pipe with inside and outside solid UPVC layers and middle layer consisting of foamed PVC. The inner and outer layers have the main function of sustaining the load while the foam layer in the middle provides rigidity to the structure of the pipe and maintains its shape.
Unplasticised polyvinyl chloride (UPVC) allows better hardness and stiffness of the product and reduces the risk of leaching of harmful any constituents into the water.
This combination produces a pipe that is 25% lighter than standard UPVC pipe and at the same time this structure allows achieving superior ring stiffness with saving in raw materials and low weight for faster and easier handling and installation. As foam core PVC pipes are meant to be buried into the ground, the rigidity of the foam layer is a much required characteristic. The systems overall flexibility facilitates its application for all domestic and commercial requirements for foul water and surface water drainage
