Lightweight uPVC Drainage Piping System
Astral Foamcore pipes are basically multilayer pipes having outer and inner layers of conventional PVC and a middle layer of foamed PVC. Outer and inner layers are designed to take the load while the middle layer of foamed PVC gives rigidity while maintaining the shape of the pipe under load. It reduces the total weight of the pipe and makes it light when compared to solid wall PVC pipes. The pipe is typical of solid wall PVC under load and the type of distortion is normally expected.
The Astral Foamcore pipe can distribute the load more evenly and does not show the same amount of distortion, as it has a unique “I-Beam” structure. Due to its ability to absorb the load, Astral Foamcore pipes are most suitable for underground drainage systems, where soil exerts pressure on pipe surfaces. In solid wall pipes, this soil pressure will rupture the pipe after some time whereas Astral Foamcore pipes give better life as foamed PVC layer will absorb pressure and make pipes “stress-free” in working conditions.
