A Slight Positive Pressure Pipe Applications New Isolation Method Summary

围绕预合成塔检修时工艺处理中遇到的隔离难题,大胆使用了一种管道封堵气囊,笔者认为这是大口径微正压管道的一种新隔离方法,是气囊在化工企业中的一种新应用。

Around the pre- treatment process synthesis tower maintenance isolation difficulties encountered, bold use of a pipe sealing bag. I think this is a new method for isolating large diameter slightly positive pressure pipes and a balloon in the chemical enterprise new application.
