.... Hydrostatic testing indicated a burst strength of 13,500 psi for the intact sections of tubing. Scanning electron microscopy and metallographic examination revealed that the tubing failed due to corrosion pitting exacerbated by stress-corrosion cracking (SCC). The pitting originated on the outer surface...

... that the cylinder pipe burst in a mixed brittle-ductile manner due to overpressurization. It is likely that the bearing strength of the pipe was slightly compromised by a low-strength layer of decarburization. Recommendations included evaluating the testing procedure for the possibility of inadvertent...
