压力容器设备中法兰设计存在的问题及对策

Problems and Countermeasures of Flange Design in Pressure Vessel Equipment

法兰在压力容器设备的运行中占据举足轻重的地位,与容器性能息息相关。为此,文章简单地阐述了压力容器法兰,明确了其类型和设计要点。在此基础上,重点探究了压力容器法兰的设计问题,发现设计中仍存在不足,如材料选择不合格、使用寿命估算存在偏差、热处理工作不到位等。针对上述问题,提出了相应的解决对策,如重视材料选择、考虑超出标准的范围、完善压力容器热处理技术,以期提高压力容器设备中法兰设计的水平,为容器安全提供保障。

Flange occupies the pivotal position in the operation of pressure vessel equipment and closely relates to the performance of vessel.For this reason,the paper simply elaborates the pressure vessel flange and make clear its type and design key point.On this basis,the design problems of pressure vessel flange are mainly explored.Some deficiencies are found in the design,such as unqualified material selection,deviation in service life estimation,inadequate heat treatment and so on.The corresponding countermeasures are put forward to solve the problems,such as attaching importance to material selection,considering the scope beyond the standard,perfecting the heat treatment technology of pressure vessel,so as to improve the level of flange design in pressure vessel equipment and provide guarantee for the safety of the vessel.
