It is known that common zinc alloys have a tendency to fail at temperatures above 60°C. Above this temperature, zinc alloys can suffer from intergranular corrosion, especially when buried in saline mud. When at high temperature, common zinc anodes may become ineffective or even detrimental to the iron and steel structure intended to be protected by the sacrificial CP system. The zinc anode suffers passivation and polarity reversal —— a dangerous condition in which zinc and steel reverse their natural polarity and steel becomes anodic to zinc, corroding itself and protecting the anode. To meet the demand of anode applications at high temperature, YUXI has developed this specialized zinc anode that can operate successfully at elevated temperatures up to 90°C.
—— Chemical Composition ——
—— Electrochemical Properties ——
* The open/closed circuit voltage is with respect to a saturated calomel electrode.
—— Practical Application ——
Our high temperature zinc anode is designed for use in tanks intended for the carriage of liquid cargo with high temperature exposure, hot subsea pipelines and heat exchangers.
