Abstract
746,110. Joints; stopping; indicating leakages. NORTH WESTERN GAS BOARD, and BELL, F. June 2, 1954 [Jan. 29, 1954], No. 2717/54. Classes 99(1) and 99(2). In means for connecting service pipes to gas mains comprising a tee-adaptor which has one end a threaded for screwing into a tapped hole in the side of the main and at the other end, in line with the end a, has a connector for the service pipe, and wherein there is a transverse bore, the bore having an opening e which is internally threaded, the bore is adapted to take an expanding buffer g for temporarily sealing the gas outlet from the main. An air passage in the form of a groove f is provided from the opening e to the service pipe connector to enable a testing apparatus screwed into the opening e to communicate with the service pipe while the opening to the gas main is still closed. The connector comprises a rubber washer b compressed to bear on the service pipe by a threaded ring c. The buffer g, of rubber or plastic material for example, is expanded by rotating a nut h whilst an air pump j and pressure gauge k are attached to the opening e ; and the service pipe is supplied with air through the groove f or a similar groove in the buffer. If the pressure is maintained for a given time the installation is regarded as satisfactory and the testing apparatus is removed and replaced by a plug.
