Cast iron soil pipe crushing strength

Feb 28, 2011 I need to confirm that a buried 30 year old cast iron pipe is ok for resistance to crushing due to new construction work above. Pr ... I suspect from the question you are asking it is probably some form of gray cast iron (and maybe indeed soil pipe for drainage as others know or have assumed). ... Of course the actual thickness and iron

    Minimum crushing strength values for pipes or pipe sections are specified in two ways (BS EN 295-1 2.9). For 100 and 150 mm diameter pipes specific values are given of 22, 28, 34 and 40 kN/m, with higher strengths permitted in steps of 6 kN/m. For larger pipes, crushing strengths are given according to class numbers, as shown in table 4 below

    The design of the pipe is site specific, i.e., the pipe is custom designed for the specific site conditions where it will be used. Therefore, the pipe specifications and pipe classes for each contract are typically unique and only apply to that contract. The supporting strength of PCCP, like that of cast iron pipe, is determined by considering
