摘要
A hydraulically installed tube plug with or without O.D surface enhancements and plug installation tooling, high pressure fluid system and method. The invention stops leaks in tubes with a plug that utilizes controlled high pressure fluid within the plug itself to radially expand the plug in place. Other plugs and plugging systems rely on mechanical methods for setting the plugs in the tubes with little or no control on the radial pressure applied to the tube. This lack of radial pressure control can result in a tubesheet ligament being over stressed (plastically deformed) or not enough pressure applied to stop the leak. The plug high pressure expansion tooling is designed with built in safety components that allow high pressure hydraulic expansion methods to be used safely in blind holes. The high pressure fluid system's design allows it to be used in hazardous environments.
