“爆破法”吹扫是指在主管道排出口用牛皮纸代替金属盲板,各个支管与设备连接处用钢盲板或阀门断开,然后用空压机向系统内逐级加压,直至排出口的牛皮纸破裂,通过气流瞬间释放,带动管道内泥砂杂物、油脂、焊渣和锈蚀物等排出主管道。关闭进气阀,在排出口重新布置牛皮纸,牛皮纸的使用从薄到厚,压力逐级增高。 “Blasting ” purge refers to the outlet of the main pipe instead of the metal blank with kraft paper, the connection of each branch and equipment with a blind or steel valve blank, and then use the air compressor to the system level by level pressure, Until the rupture of the outlet kraft paper, through the instantaneous release of air flow, drive debris in the pipeline debris, grease, welding slag and rust discharge from the main pipeline. Close the intake valve, re-layout kraft paper in the discharge port, the use of kraft paper from thin to thick, the pressure increased step by step.
