Case Histories of Some Failures of Fittings, Valves, and Tanks in the Petroleum Industry




Abstract: Several examples of failure analyses conducted on tube fittings, valves, and storage tanks used in the petroleum industry are summarized. Failures examined include weld failures in cast steel ball valves, fatigue cracks in stainless steel compression fittings, and pitting damage in stainless steel storage tanks and tubing. Causes of the failures and recommendations to minimize future failures are also presented.
