摘要： A system and method for pipe insertion in live gas mains includes isolating a section of the gas main and taking measurements of service line connection points. This data is then used to prepare a pipe to be inserted into the gas main by drilling holes and applying fittings at the appropriate locations. The prepared pipe is then inserted into the gas main and the service lines are connected to it without the need to excavate the street over each service connection. The inserted pipe is then fluidly connected to the cut ends of the gas main and gas flow is routed through the newly inserted pipe and the attached service lines, while gas continues to flow through the original portions of the gas main that still remain in service.
