Experience in non-destructive testing of 7075-T651 aluminum (Sy = 72 ksi, KIC = 22 ksi in1/2) pressurized pipes dictates that the minimum detectable longitudinal crack length is 10 mm. Thus, a longitudinal crack of length 10 mm could escape detection and be present at any time. The pipes transmit a flow of natural gas and the presence of a crack would not alter the internal pressure. What maximum internal pressure would you recommend? Neglect the pipe curvature when determining the stress intensity factor.
