Progresses in Disaster Prevention and Mitigation Technology for Pressure Equipment of Hazardous Chemicals in China

Abstract

Abstract: How to ensure that the pressure equipment of hazardous chemicals “no leak, no explosion” in the disaster environment, and how to quickly identify and evaluate the damage of the equipment after the disaster occured, are the technical problems that need to be solved urgently in engineering field. Herein, the research progresses including the wind vibration response analysis, fatigue life prediction and structure optimization technology of tall tower vessels, safety evaluation technology of large scale suspension and offset of submarine oil and gas pipeline, and rapid detection and diagnosis technology of pressure vessel damage due to fire overburning in recent years in China were introduced. Finally, in combination with current development trend of industrial Internet of Things, big data and artificial intelligence, suggestions for research of disaster prevention and mitigation technology for pressure equipment of hazardous materials in the future were proposed.

Key words: hazardous chemicals； pressure vessel, pressure pipeline, typhoon, wave current, fire
