SRPE combines the strength of steel with the flexibility of plastic and can be installed with up to 25% flow.
DuroMaxx steel-reinforced polyethylene (SRPE) pipe technology combines the strength of steel with the durability of HDB pressure-rated plastic. Reinforced bell-and-spigot or fully welded joints easily meet water tightness standards for ASTM D3212. With diameters from 30 to 120 in., standards lengths of 14 to 24 ft, a compact wall profile and project-specific custom fittings, it is a solution for sanitary sewer overflow tanks and wastewater pipeline applications.
For closed-system storm and sanitary sewers or culverts with limited access, engineers should consider utilizing SPR polyethylene, which can structurally rehabilitate brick, concrete, plastic or corrugated metal pipes from 30 to 118 in., with the equipment fitting through a 22-in. manhole opening. Installation can occur with up to 25% of the flow present and it requires no bypass pumping, greatly reducing installation time and cost.
