Protection of steel piles in harbours by using DZ tape and cathodic polarization

  • Dai Zhongdao
Article

Abstract

An anticorrosion method using wet DZ1 tape and electrochemical cathodic protection is suggested. The advantages of this method over internationally patented sealing techniques lie in its electrochemically open system, high adsorption of OH with resultant rise of pH, exchangeable electrolytes, simple pretreatment of the steel pipe, simplicity of application, lower cost, better protection even under ebb tide, and low transmission of oxygen and corrosion products.
