In-Depth Analysis and Reflection on Explosion of Welded Insulated Cylinder for Liquid Oxygen

Abstract:

This article provides a comprehensive analysis on an explosion of welded insulted cylinder for liquid oxygen during unloading occurred in a company in 2014. The possible causes of the accidents are deduced through analysis on the operating principles of welded insulated cylinders, explosion energy estimation and related performance tests. On the basis of the accident analysis, this article presents that great importance should be attached to the safety in filling of welded insulated cylinders, replacement prior to filling and regular inspections, and also indicates the gap in currently existing rules on periodic examinations of welded insulated cylinders in China.
