压力管道作为特种设备,在现代工业生产中应用较为广泛。现阶段压力管道缺陷、事故状况、管道爆炸、漏气等状况较多,对生产社会造成了重大危害,需要引起足够重视。一般压力管道缺陷的成因在于介质腐蚀、压强、温度及焊接工艺操作不当导致。本文对压力管道焊接缺陷状况进行了分析,并针对缺陷成因进行了相应的解决对策分析,旨在为压力管道的使用寿命和焊接质量提供一定理论支撑。 Pressure pipe as a special equipment, in the modern industrial production is widely used. At this stage, there are many situations such as pressure pipeline defects, accident conditions, pipeline explosions and gas leakage, which have caused great harm to the production society and need to be given enough attention. The causes of the general pressure pipeline defects in medium corrosion, pressure, temperature and welding process caused by improper operation. This paper analyzes the status of the welding defects of the pressure pipe and analyzes the solutions to the causes of the defects in order to provide some theoretical support for the service life and welding quality of the pressure pipe.
