Al-rubaiey AU - Naser Korde Zed PY - 2014 VL - 32 IS - 1 Part (A) Engineering SP - 154 EP - 161 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - The present work involves using Impressed Current Cathodic ProtectionTechnique (ICCPT), to prevent corrosion of buried underground steel pipelines.Polarization method using galvanokinetic technique was used to study the behavior of steel pipelines in Iraqi soil. The soil resistivity in this work is equivalent to NaCl solution (5, 10, 15, 20 and 25) NaCl concentrations. The resistivities play a strong role in corrosion rates, where corrosion rate increases with decreasing environment resistivity and increases with increasing the concentrations of NaCl for constant surface area. The object of this study is using a cathodic protection system by impressed current supplied with solar energy panels applied to steel pipelines. The efficiency of cathodic protection depending on the soil resistivity in the presentwork with different electric source and solar energy source are reached to the (92.3-94.5).
