TOP PIPE HDPE Corrugated Piping Systems provide a great solution to both new and existing infrastructure systems. These pipe are manufactured using a double-wall system and are commonly referred to as DWC pipes. The outer layer of the pipe is corrugated, which is designed to give the pipe enhanced stiffness, absorb external pressure and reduce overall weight of the pipe. The inner layer has a smooth texture, designed to maximise flow efficiency and minimise friction.
HDPE Corrugated Piping has long been the preferred piping choice in Asia, Europe and North America. They are rapidly replacing more primitive systems such as GRP (fibreglass), concrete and clay piping due to their comprehensive advantages, superior performance levels and long service life.
TOP-PIPE HDPE Corrugated Pipes are produced in accordance with the EN 13476 standards and is available in diameters from 225mm up to 600mm.
