Design and Application of Steel Pipe Surface Washing Device on 3PE Anti-corrosion Line

Described here in the paper is the current situation of the 3PE anti-corrosion coating line.And analyzed are the design thinking and design scheme of the steel pipe washing device as installed on the said coating line. Moreover the operation effectiveness of the said washing device is elaborated. It is regarded via the analysis that due to the water-washing treatment, the surface dust level and the surface salt content of the steel pipe are improved so as to get the corrosionresistance of the 3PE pipe enhanced;the above mentioned steel pipe water-washing process possesses the advantages like energysaving and environment protection to avoid the environment pollution as caused by conventional pickling treatment process;and finally the said water-washing device features such advantages as moderate investment, easy operation, and low risk.
