CISBOTS - Robots for Internal Service of Gas Pipes

ESI provides custom-made robots for inspection and internal repair of 6" - 12" and 12" - 36" diameter cast iron natural gas mains.

CISBOTS - Robotic systems used to internally seal bell-and-spigot type joints by injecting liquid anaerobic sealant into the jute packing of the joint. Anaerobic injection is used to seal the joints. The internal joint sealing systems have proven to be an effective method of sealing of the joints.

CISBOTS - Robotic system uses anaerobic sealant injection for repairing leaking joints, or as a preventive measure. Plastic gasket formed inside the joint cavity by the cured sealant is a more effective and durable seal than the original lead seal.
