Guide for PVC sewer force mains uses recently developed method for cyclic-fatigue design.
Assists engineers to determine PVC pipe wall thickness using expected design values for working pressure, surge pressures (both occasional and recurring) and hydrostatic test pressure based on pipe size and OD regimen.
Online calculator for PVC sewer force mains uses project parameters to calculate expected cyclic life and determine the appropriate DR for projects. Multiple surge events can be added, which the calculator can easily combine to provide resulting cyclic life. Up to four surge events can be included.
Recent hydraulic research on new and in-service PVC pipe has confirmed that industry-recommended flow coefficients are conservative for design of pressure and non-pressure pipes.
This technical report examines head loss and pumping costs over 100-years for PVC and ductile iron pipe.
PVC Pressure Pipe Standards used in force mains are summarized.
