过滤器常工作在高温高压的工况下,因此要对其各焊缝进行严格的无损检测。某机械厂生产的蓝式过滤器,利用HS600数字式超声波探伤仪分别实现了各焊缝的超声检测,方法简单可行,可供相关从业人员参考。 Filters often work in the high temperature and pressure conditions, so to the seam of their strict non-destructive testing. The blue filter produced by a machinery factory, using HS600 digital ultrasonic flaw detector to achieve the ultrasonic testing of each weld, the method is simple and feasible for the relevant practitioners for reference.
