Abstract

In order to analyze the failure cause of welding insulation cylinder, to which explosion had happened, in a filling station, a series of experiments and analysis were taken, including macroscopic analysis, chemical composition analysis, fracture Analysis, metallographic examination and so on. The results showed that irrational structure led to fatigue cracking of fillet weld, connecting the inner-shell and neck pipe, and then pure oxygen continuously leaked into the vacuum interlayer. Friction heat or static electricity generating with the leaking finally caused combustion and explosion of flammable insulation materials in the interlayer. At the end, proposals were put forward.
