1 前言锅炉压力容器是具有爆炸危险性的特种承压设备,我国锅炉压力容器安全管理工作经历了从无序到有序的过程。虽然从八十年代初期起在全国范围内逐渐开展了在役锅炉压力容器的逐台普查登记和定期检验工作,使一部分问题比较严重的设备逐步淘汰。但由于锅炉压力容器质量受当时材料、工艺、人员素质和制造水平的制约,在使用中又受到使用工况,操作者水平等影响,因此,在役锅炉压力容器存在缺陷是不可避免的。对带缺陷的锅炉压力容器进行改变工况条件或报废的处理,会造成大量的浪费,适时地对锅炉压力容器的缺陷状况进行分析就显得十分重要。
1 Preface Boiler pressure vessel is a special pressure-bearing equipment with explosion danger. The safety management of boiler pressure vessel in our country has undergone a process from disorder to order. Since the early 1980s, a nationwide census enumeration and periodic inspection of in-service boiler pressure vessels has been gradually carried out to phase out some of the more problematic equipment. However, the quality of the boiler pressure vessel is restricted by the material, technology, personnel quality and manufacturing level at that time, and it is also affected by the working conditions and the level of the operator in use. Therefore, the existing defects of the pressure vessel in the boiler are inevitable. It is very important to analyze the defect condition of the boiler pressure vessel in time because of the change of working conditions or scrapped disposal of the defective boiler pressure vessel.
