ON DEMAND - Isolation joints in pipelines may be subject to over-voltage failure due to lightning and, in some applications, AC faults. Without proper protection, such over-voltage events can damage the isolation kit and/or the flange and possibly ignite flammable contents within the pipeline. Various types of isolation joints appear in pipeline facilities, including fittings in measurement tubing, threaded unions, flanged isolators, and monolithic isolators. All types can fail if not properly protected.
Over-voltage protection against both lightning and AC fault conditions is possible using appropriately rated products and is required by many regulatory agencies for protection of equipment and personnel.
This webinar reviews the various types of isolation joints typical on a pipeline and explain why it is important to apply over-voltage protection on isolation joints. The use of solid-state over-voltage protection devices is described and compared to other common solutions. Key application guidelines are presented for these devices for use with isolation joints.
