Introducing solutions for preventing electrocorrosion in high temperature and high load environments!
In the design and maintenance of plant piping and industrial machinery, preventing "electrolysis (dissimilar metal contact corrosion, galvanic corrosion)" that occurs at points where different metals come into contact is an extremely important technical challenge to ensure the longevity and safe operation of equipment. To block the weak current (corrosion current) generated by the potential difference between metals, it is necessary to completely electrically insulate the flange fastening parts (bolts, nuts, and seating surfaces). Conventional fluororesin (PTFE) sleeves are prone to deformation due to creep (stress relaxation) in high-temperature environments, which may require consideration of reduced tightening axial force and insulation performance. In this article, our company, a specialist manufacturer of industrial sealing materials and insulating materials, will explain the material characteristics of "mica," which is suitable for high-temperature environments, the selection criteria for specific fastening parts (insulating sleeves and mica washers), strict adherence rules during installation, and the total coordination of high-temperature insulating gaskets that should be used in conjunction. *For detailed content of the column, please refer to the related link.
