Disponible en CD en formato PDF Transcripción del abstract original del autor: Aged house pipes that have been in service for several years after installation are liable to the risk of gas leaks and consequential incidents due to corrosion. As this risk increases with time, gas operators are engaged in countermeasures, including pipe replacement. The house pipes, however, are the property of the customer who is therefore required to pay the costs for pipe improvement. This is currently the main factor for the holdup in improvement work. To overcome this problem, the Japan Gas Association has been commissioned by the Ministry of Economy, Trade and Industry to develop a novel renewal method that will help save improvement costs by inserting a new pipe inside the old one. This project is due to be implemented on a five-year schedule from fiscal 2001. The development of this technology has a promising potential for further enhancing the safety of city gas supply as a result of the accelerated rate of renewal of aged house pipes.
