Abstract Special corrosion protection measures in fabrication of chemical equipment. An essential pre‐condition for uninterrupted and safe operation of equipment is a proper selection of materials with regard to service conditions, design, and fabrication. In case of difficulties with the application of unprotected metallic materials suitable additional measures must be applied to ensure proper performance of the equipment. Basically, there are four types of measures. The material can be improved by modification of the composition or fabrication (e. g. powder metallurgical, remelt techniques, accurate welding); the material can be protected by the application of a duplex‐system (lining, cladding, plating); the electrochemical performance of the metal can be influenced by superimposed currents (cathodic/ anodic protection); and last but not least a change in service conditions can meet the requirements for materials performance. To ensure satisfactory performance of protective measures, supervision of application, installation, and in‐service behaviour is a must.
