Iplex BlackMAX™ and SewerMAX™ pipes are manufactured to a high standard in accordance with the Australian Standard AS/NZ 5065 - Polyethylene and polypropylene pipes & fittings for drainage and sewerage application. Whilst most commonly used in underground drain and sewer applications, when provided with appropriate WWW. I P L E X . CO M. A U 7 support these products are equally suitable for installation above ground in suspended stormwater systems. The pipes highly effective jointing system protects against sewer leakage into groundwater and infiltration of storm run-off into sewer systems whilst their smooth internal surfaces maintain gravity flow at very low gradients. The high ring strain tolerance of polypropylene enables the pipe to be safely buried without risk of buckling or collapse in a very broad range of ground conditions, provided adequate compacted bedding and support is provided during installation. BlackMAX™ and SewerMAX™ pipes are a fraction of the weight of equivalent concrete or earthen ware pipes providing faster installation for contractors, often without the need for mechanical handling equipment. Polypropylene is a tough, abrasion resistant material with exceptional chemical resistance and will never rust or spall, making these pipes ideally suited for use in marine and corrosive soil environments. Polypropylene pipe used in stormwater applications has no effect on the pH or chemistry of run-off water.
