Abstract

See full text

A modular plug for installation into large diameter pipelines that provides a reliable and secure seal within the pipeline to be serviced thereby increasing the safety of the people working on the secured side of the plug. The plug is modular in construction and suited for easy installation within large pipelines. The plug is generally formed as a large circular plate formed from modular sections. Along the division lines the plug pieces include grooves and a gasket therein. Reinforcing jacks extend outwardly from the plug and exert pressure against the pipeline to retain the plug geometry and position. Also, around the periphery of the plug is shown an inflatable rubber seal.
