| Abstract: | External forces caused by earth and heave vehicle on PE pipe for underground fire protection services are investigated and analyzed. The Spangler Equation is introduced to calculate the pipe deflection. The sufficient pipe stiffness to remain intact and not leak when exposed to external forces is evaluated on acceptable deflection which is not exceed 5 percent of the inside diameter of the pipe. |
