A system designed to prevent the flow of electrical current or fluids between two joined pipe flanges constitutes a critical component in pipeline integrity. Typically composed of sleeves, gaskets, and washers fabricated from non-conductive materials, this system is installed at the joint between flanged connections. For example, in a pipeline transporting corrosive chemicals, this system can eliminate galvanic corrosion by electrically isolating dissimilar metals within the flanged joint.
The employment of such a system offers substantial benefits, including the mitigation of corrosion, prevention of stray current issues, and enhancement of overall pipeline safety. Its implementation has a historical context rooted in the growing awareness of the damaging effects of corrosion in industrial piping systems, leading to the development of engineered solutions to address these concerns. Properly installed, this protective measure prolongs the lifespan of pipelines and reduces maintenance costs associated with corrosion-related failures.
