Safety assessment system for pressure vessels with flaws

A safety assessment expert system based on BS7910 Standard was developed to evaluate the safety of pressure vessels with flaws in power supply systems quickly.The expert system consists of flaw-recombination module and flaw-evaluation module.It is an effective supplementary way for the engineers and technicians to master the complicated evaluation procedure,and make rapid and accurate safety assessment.The expert system was applied to evaluate the safety of surface crack in the circumferential welded seam of air compression tank.The result showed that the system provided technical support for the further operation of pressure vessels with flaws.
