在容器的定期检验中,经常遇到在役压力容器中含有与原设计图纸不符的结构,如果不加以合理的分析,简单的不允许这些结构的存在,会造成不必要的返修,甚至有可能将合乎于使用要求的设备判废。更为严重的是,若结构返修不当,反而会增加新的危险。只有对与原设计图纸不符的结构进行合理的分析,科学的评定,才能既保证在役压力容器的安全使用,又可获得较好的经济性。图1为一超高压水晶釜,用户为了监控反应釜
In the periodic inspection of the container, it is often encountered that the pressure vessel in service contains structures that do not conform to the original design drawings. If not properly analyzed, simply not allowing the existence of these structures will result in unnecessary rework and may even be possible Will meet the requirements of the equipment sentenced to waste. What is more serious is that if the structure is not properly repaired, it will add new dangers. Only with the original design drawings do not match the structure of a reasonable analysis, scientific assessment, in order to both ensure the safe use of pressure vessels in service, but also get better economy.
