压力容器焊接质量分析及控制

Analysis and Control of Welding Quality of Pressure Vessel

在我国的化工领域中对于压力容器的使用频率相对较高,其是一类较为特别的容器,有着较高的结构化程度。一般都会在压力以及温度都很高的环境中进行使用。压力容器的使用特征以及结构特征都决定了这一类容器的使用危险系数极高,压力容器的内部构造之中的物质保存要求以及外部环境原因的影响使得对于这一类压力容器进行焊接的难度极大。在进行压力容器焊接的过程里应当把控好一系列的细节并且使得不同环节的工作配合起来。一般来说如果化工环境是合格的,焊接的效果是否优秀就决定了压力容器使用的效果和稳定性,因此针对压力容器的焊接工作控制一定要到位。由于上述原因压力容器在我国属于特种设备,还有着相应的安全检查制度进行规范,从而保障对于压力容器的质量监督工作能够在规范、标准的制度管理中实现,让压力容器的运行使用更加安全。文中就压力容器焊接质量的影响因素进行分析和讨论,并提出相应措施控制压力容器的焊接质量,以期为相关工作者提供参考。

In the field of chemical industry in China,the use of pressure vessels is relatively high.They are a special kind of vessels with a high degree of structure.They are generally used in environments with high pressure and temperature.The use characteristics and structural characteristics of pressure vessels determine that the use risk coefficient of this type of vessels is very high.The material preservation requirements in the internal structure of pressure vessels and the impact of external environmental factors make it extremely difficult to weld this type of pressure vessels.In the process of pressure vessel welding,a series of details should be well controlled and the work of different links should be coordinated.Generally speaking,if the chemical environment is qualified,whether the welding effect is excellent or not determines the effect and stability of the pressure vessel,so the welding work control for the pressure vessel must be in place.For the above reasons,pressure vessels belong to special equipment in China,and there is also a corresponding safety inspection system to regulate,so as to ensure that the quality supervision of pressure vessels can be realized in the system management of specifications and standards,and make the operation and use of pressure vessels safer.This paper analyzes and discusses the factors affecting the welding quality of pressure vessels,and puts forward corresponding measures to control the welding quality of pressure vessels,in order to provide reference for relevant workers.
