Chemical processing units are engaged in a battle against corrosion to ensure that processes operate safely and consistently. Corrosion vigorously affects different types of materials ranging from metals to even plastics. Various processes demand a variety of materials to secure the material from corrosion and its ensuing issues. Different types of corrosion- susceptible equipment, like … Continue reading High nickel alloys Inconel and Hastelloy bars for high temperature corrosion

Carbon steels can easily deal with gaseous chlorine at low temperatures and in the absence of moisture. But if water is present, chlorine becomes vigorously corrosive to several metals. In the same manner, dry hydrogen chloride is not corrosive to various metals. As soon as it is dissolved in water HCl is developed and it … Continue reading How do different alloys perform in dry and moist chlorine media?

Pure phosphoric acid does not possess a suitable oxidizing power and is called as a non-oxidizing acid similar to dilute sulfuric acid. On the other hand, commercial phosphoric acid possesses contaminants of fluorides, chlorides etc that significantly increase its vigorousness. Oxidizing compounds like ferric salts, may also occur to influence the corrosion. Probably the variations … Continue reading Which materials can perform well in Phosphoric acid environments?
