Así pues, se evaluó la efectividad del sistema por Corriente Impresa, midiendo el potencial electroquímico y la caída óhmica (IR), mediante la técnica de la interrupción de la corriente (IOP). El espesor de los tanques se midió por ultrasonido y el análisis físico-químico se realizó al suelo para conocer la humedad, índice de plasticidad y corrosividad. Se encontró que el suelo donde se encuentran apoyados los tanques (sobre losas de hormigón armado) es un terreno con una resistividad entre 10 916.15 y 14 363.36 &#937;/cm, por lo que tiene una baja corrosividad. El SPC es efectivo ya que presente baja velocidad de corrosión 0.152 mm/año. Con la interrupción de corriente se determinó que el 53% de la base de los tanques de acero revestidas y protegidas catódicamente cumplen con los criterios de protección catódica del acero con polarización de +100 mV., establecido en la Norma NACE Estándar SP 0169-2013.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The present research has evaluated the cathodic protection system applied to fuel storage tanks base at the Terminal de productos limpios of EP PETROECUADOR public company located in Riobamba. It was evaluated during January and May, 2018. Therefore, it studied the effectiveness of the CPS by printed current which calculates the electrochemical potential and the ohmic drop (IR) by the interruption current technique (ICT). The tanks thickness was rated by ultrasound. In order to know the humidity, plasticity index and corrosivity of the soil we did a physical-chemical analysis. It was founded that the soil where the tanks are supported on (reinforced concrete slabs) has a resistivity of 10 916.15 and 14 363.36 &#937; / cm, which shows a low corrosivity. We concluded that the CPS is effective since it has a low corrosion rate of 0.152 mm per year. The ICT found that 53% of the base of steel coated and cathodically protected tanks fulfill the criteria of cathodic protection of steel polarization (+100 mV) that is established in the NACE Prescription Standard SP 0169-2013.]]></p></abstract>
