Abstract: Failure events take place in natural gas pipelines, such as corrosion puncture, corrosion crack, and third party damage. Welding, clamp, combination material were applied to repaire the failure pipeline, so there is more than one kind of repair technologys for a certain failure. Based on the different operatonal, evironment conditons and charactericals of these first-aid repair technologies, the t
echnology and ecomical fassibility can be anlyzed with the analytic hierarchy process. This method already has a successful application in an actual in-use pipeline, the optimization repair method is confirmed and can guide the first-aid repair response management, the application result also shows an effective reduction of the repair time and cost.
Key words: natural gas pipeline; first-aid repair technology; adaptability; analytic hierarchy process
