Installation of Fiberglass Pipe on Sewer Force Main Projects


The stringent design criteria set for large diameter sewer force mains encompass many factors. These mains must resist external loading from backfill and live loads prior to the line being pressurized. Once pressurized, the pipe must withstand the combined effects of both the internal pressure and external loads. In addition, the pipe must be corrosion resistant to the interior flow and, in many cases, to severe external corrosive environment. If thrust blocking is not provided, the pipeline must be capable of resisting the unbalanced forces at bends, wyes, tees, etc. By meeting all of these criteria, the pipe should perform satisfactorily over the design life of the project.
