球罐缺陷安全评定,往往会对球罐质量得出定性印象或定量评价,这对缺陷评定过程选取安全系数至关重要,是一个值得探讨的问题。影响在役球罐质量因素很多,如设计,材质,组装焊接质量,环境介质,工况,安全管理等。八十年代经过设计与制造贯彻标准与取证制度,推行质量管理体系,焊接与探伤人员 The safety assessment of the spherical tank defects often leads to the qualitative impression or quantitative evaluation of the spherical tank quality. It is very important to select the safety factor in the defect assessment process, which is worth discussing. There are many factors affecting the quality of the tank in service, such as design, materials, assembly welding quality, environmental media, working conditions, safety management and so on. Eighties after the design and manufacture of standards and the implementation of evidence collection system, the implementation of quality management system, welding and testing staff
