BURIED PIPE CALCULATIONS - adpf.ae

The buried pipe is subjected to radial external loads composed of vertical loads and possibly the hydrostatic pressure of ground water and internal vacuum, if the latter two are present. The summation of appropriate external loads should be equal to or less than the allowable buckling pressure which is determined by the following equation. q

HDPE Pipe

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs. NEVER use an inflatable plug when its failure could cause injury or astrophic damage or as the only means of protection for personnel working downstream.
