DUCTILE IRON PIPE

2014-5-21  Ductile Iron pipe can withstand severe crushing loads. The ring test, shown above, determines a pipe’s ability to withstand load over a relatively small area, as would occur in rocky terrain where the pressure of a single rock, plus all the backfill above it, could cause weaker materials to fail. A deflection gauge on the ring-crushing

2010-4-11  Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.
