Support renewal, rehabilitation work, and maintenance management through temporary closure of the pipeline and bypass.
In sewer and drainage facilities, it is necessary to temporarily stop the flow of water and sewage in the construction section when updating, rehabilitating, repairing, or inspecting aging pipelines and equipment. However, it is not necessary to stop the entire facility's functions. At Rokubiryu Rubber, we propose pipeline closure products that allow for construction while minimizing the impact on facility operations by temporarily closing the necessary sections for construction and ensuring flow through a bypass as needed. We offer the "Hexagate Plug II" for large-diameter pipelines and the "Hexaplug," which accommodates a wide range of conditions from small to large diameters, selecting and designing them according to pipe diameter, pipe shape, construction conditions, and delivery conditions. We also address the concept of redundancy, ensuring flow functionality while closing the pipeline. "I want to update without stopping the facility." "I only want to temporarily close the construction section." "I want to carry out construction while bypassing." "I cannot accommodate with off-the-shelf products." If you have any concerns at the site, please feel free to consult with us.

basic information
【Hexagate Plug II】 Closes large-diameter pipelines and supports renewal work. It is a water stop wall that temporarily closes the construction section for the renewal and rehabilitation work of large-diameter pipelines and for maintenance management. In addition to designs tailored to site conditions, it also accommodates plans to ensure downstream flow by providing large-diameter bypass pipes during construction. If you are having trouble with closure, bypass, or delivery conditions for large-diameter pipelines, please consult us. 【Hexaplug】 Allows for closure of necessary locations for only the required duration. This product is used to temporarily close pipelines during piping work, equipment renewal and inspection, and maintenance management. It accommodates a wide range from small to large diameters and offers specifications tailored to the construction locations such as inside the pipe and at the pipe ends. In sites with flowing water, it can also accommodate methods that involve creating a bypass to divert the flow during construction. Please consult us from the stage of "Can this piping be used?" or "Can we accommodate these construction conditions?" *We will confirm the site conditions and propose products and specifications tailored to the purpose of pipeline closure, bypass, etc.
