聚乙烯(Polyethylene,PE)管道因具有接口稳定、材料抗冲击、抗开裂、耐老化及耐腐蚀等优点,已广泛应用于埋设燃气管道.基于此,首先介绍声波定位法和多频管中电流法(Pipeline Current Mapper,PCM)的基本工作原理,其次分析应用声波定位法和PCM定位法探测燃气PE管道的优缺点,最后进行案例分析.
Engineering Case Study on the Combined Application of Acoustic Positioning Method and PCM Positioning Method
Polyethylene(PE)pipes have been widely used in buried gas pipelines due to their advantages such as stable interface,material impact resistance,crack resistance,aging resistance,and corrosion resistance.Based on this,the basic working principles of acoustic positioning method and Pipeline Current Mapper(PCM)in multi frequency tubes are first introduced.Secondly,the advantages and disadvantages of using acoustic positioning method and PCM positioning method to detect gas PE pipelines are analyzed,and finally,a case study is conducted.
