Robotic technology is currently being operated in underground gas pipelines in four of the world?s most notable cities to greatly reduce methane emissions and cut costs to gas utility customers. The CISBOT internal cast iron joint sealing robot is a game-changing, innovative pipeline rehabilitation system that, through trenchless technology, enters live gas mains to repair infrastructure?revolutionizing the way gas utilities stop and prevent gas leaks.
Between 1800 and the mid-1900s cast iron gas mains were installed under city streets to deliver gas to homes and businesses. Through decades of use the pipelines? joints started to dry out and are now prone to forming leaks. Gas utilities that operate cast iron are now faced with the decision to replace the pipe or maintain it.
Operating in 100 percent live gas environments, CISBOT drills and injects anaerobic sealant into every joint in the gas main forming a seal that is proven by Cornell University studies to last for 50 years. This process stops gas leaks and proactively prevents gas leaks from forming ? a priceless benefit to ensure the safety and well-being of the community and the environment.
Also, because of its small site footprint and ability to work underground, CISBOT nearly eliminates the public disruption often associated with typical utility maintenance. This non-intrusive work benefits residents and businesses because gas service remains online during the procedure. Furthermore, larger cast iron pipes are often in densely populated, traffic-sensitive locations, so CISBOT can increase the safety of the gas main with significantly less interruption to the daily activities of the community.
CISBOT is a reliable and alternative method to cast iron pipe replacement and other forms of pipeline rehabilitation that often requires excessive or large excavations, or even taking the gas main out of service. The robot?s work is significantly safer, more accurate and more efficient, allowing gas utilities to save money, time and improve customer satisfaction by reducing permit, engineering and restoration costs, and eliminating the disruption caused by direct burial construction.
Since 2010, CISBOT operations have grown rapidly. The robot is now commercially available and is currently working to enhance the pipeline infrastructure in New York City, Boston, London and Edinburgh.
Not only is CISBOT transforming the methods used to derisk underground infrastructure and evolving the way gas utilities work to maintain the safety and reliability of cast iron pipelines, but it is also positively impacting the environment and community by stopping and preventing gas leaks.
