压力容器在长期运行中,往往会出现腐蚀,磨损、裂纹、变形等缺陷。这些缺陷如不及时处理,会给压力容器的运行安全造成威胁,如果处理不当,会给压力容器带来新的事故隐患。所以,将压力容器修理质量控制与监督,作为安全管理工作一个重要环节。由于,压力容器种类繁杂,工作条件差别也较大,因此,只有对修理质量的影响因素严格控制,才能保证压力容器的修理质量。 Pressure vessels in the long run, often appear corrosion, wear, cracks, deformation and other defects. If these defects are not dealt with promptly, it will pose a threat to the operation safety of the pressure vessel. If handled improperly, it will bring new potential accidents to the pressure vessel. Therefore, the pressure vessel repair quality control and supervision, as an important part of safety management. Because of the variety of pressure vessels, the working conditions are also different, therefore, only the quality of the repair of the factors strictly controlled to ensure the quality of the pressure vessel repair.
