Hydraulic Characteristics of PVC Pipe in Sanitary Sewers

hydraulic characteristics of PVC pipe have been measured in laboratory studies for both open channel flow conditions, Neale and Price (1), and for full flow conditions, Jeppson (2). However, no studies are known to exist which have determined these hydraulic characteristics of PVC pipe in the field.

DuroMaxx SRPE Pipe from Contech Engineered Solutions

DuroMaxx SRPE provides the lightweight, low-cost structural advantages of traditional HDPE with none of the disadvantages. The built-in capacity of the steel reinforced ribs ensures the pipe will not creep or buckle. DuroMaxx can be twice as stiff as non-steel reinforced HDPE pipe, as it is more resistant to the effect of temperature and sunlight.
