APL APOLLO Non-Pressure Polyvinyl Chloride (PVC-U) Pipes are rigid no-lasticised pipes with good surface sturdiness and tensile resistance. They also come with a high compressive rating and pipe safety factor. With extensive use in underground drainage and sewerage systems, these PVC-U pipes are also manufactured for the conveyance of surface water and potable water. Internal and external discharge piping are also widely used in industrial and civil high buildings.
