Abstract

PURPOSE: To easily carry out the replacing and repairing of an oil supply pipe laid between oil-filled machines disposed inside and outside a sound-proof wall, by using two communication pipe joints and a vibration-proof pipe joint.
CONSTITUTION: A vibration-proof pipe joint 14 is temporarily set between an oil- filled machine on the inner side of a sound-proof wall 1 and the first communication pipe joint 15 with the first communication pipe joint 15 passed through the sound-proof wall 1. The second communication pipe 16 is then perpendicularly inserted and temporarily set between the first communication pipe 15 and an filled- oil machine on the outer side of the sound-proof wall 1. Joint portions to which the first and second communication pipe joints 15, 16 are not set are temporarily welded, and the communication pipe joints are then removed to subject the temporarily welded joint portions to regular welding. Oil-tight packings are then installed in the first and second communication pipe joints 15, 16. The vibration-proof pipe joint 14 and the first communication pipe joint 15 are tightened in the direction of the axis of a vibration-proof member, and the second communication pipe joint 16 are perpendicularly inserted and temporarily set. The pipe joints 14, 15 are then untightened, and the pipe joints 14, 15, 16 and oil-filled machines on the inner sides of the sound-proof wall are connected together properly.
