Upgrade water infrastructure while maintaining facility operations.

Support pipeline renewal, rehabilitation, and maintenance through temporary pipeline closure and bypass solutions.

Pipeline Closure and Bypass Solutions for Infrastructure Renewal In sewerage and drainage facilities, aging pipelines and equipment often require renewal, rehabilitation, repair, or inspection. These activities may involve temporarily isolating sections of a pipeline. However, depending on site conditions, it may be possible to carry out the work while maintaining essential facility operations. Mutsubishi Rubber offers pipeline closure and bypass solutions designed to minimize disruption to facility operations. By temporarily isolating the sections where work is required and providing bypass routes when necessary, our products support maintenance and renewal projects while helping maintain downstream flow. Our product lineup includes the **Hexagate Plug II**, a temporary closure system for large-diameter pipelines, and the **Hexaplug**, which accommodates a wide range of pipe sizes and applications. We offer solutions tailored to pipe diameter, pipe shape, installation conditions, and site access requirements. These solutions also support **redundancy planning**, helping maintain flow through alternative routes while specific pipeline sections are temporarily isolated. **Are you facing any of these challenges?** - You want to upgrade aging infrastructure while maintaining facility operations. - You need to temporarily isolate only the section under construction. - You want to maintain flow through a bypass during construction. - Standard products do not meet your site's requirements. **Contact Mutsubishi Rubber to discuss a solution tailored to your project.**

basic information

【Hexagate Plug II】 **Supporting large-diameter pipeline renewal and rehabilitation.** The Hexagate Plug II is a temporary pipeline closure system designed for renewal, rehabilitation, and maintenance work on large-diameter pipelines. It can be customized to suit site-specific conditions and supports construction plans that maintain downstream flow through large-diameter bypass pipelines. If you are facing challenges involving temporary closure, bypass arrangements, or installation constraints for large-diameter pipelines, please contact us. 【Hexaplug】 **Temporary pipeline closure, where and when you need it.** The Hexaplug is designed to temporarily close pipelines during piping work, equipment upgrades, inspections, and maintenance activities. Available for a wide range of pipe diameters, from small to large, it offers configurations suited to different installation locations, including inside pipes and at pipe ends. For pipelines with flowing water, bypass-compatible configurations are also available to help divert flow during construction. Whether you are unsure if a particular pipeline can be closed or need a solution for challenging installation conditions, please contact us. --- We assess site-specific conditions and recommend products and configurations suited to your pipeline closure and bypass requirements.
