AMEX process can return system to use within hours
In North America, only a small percentage (3--4%) of gas pipe installation and rehabilitation utilizes trenchless technology. Statistics from the American Gas Association show that the gas industry annually installs approximately 25,000 miles of new and replacement distribution lines each year. The rehabilitation and upgrading of gas distribution mains have become more important to gas utilities nationwide as their systems begin to show the inevitable signs of age. Patch and repair methods are often temporary stopgap measures that don`t solve the real problems of deteriorating pipelines. Yet, tight operating budgets and the location of gas lines on busy thoroughfares often prohibit trenching and other activities associated with installation of a new main. Miller Pipeline Corp. offers utilities lining technology for the rehabilitation of gas distribution pipelines at a fraction of the cost of replacement. Company officials say there is no loss of flow capacity and services can be tapped directly without the need for special fittings. The lining system provides zero-migration of gas after installation and will allow a pressure upgrade for the line. This paper reviews the cleaning and lining process used.
