PURPOSE:To form a rubber lining of uniform thickness efficiently in a short time by a method wherein a rubber lining material is inserted into and pressure-bonded on the inner surface of a piping in the installed state, and then a rubber lining adaptor is inserted and pressure-bonded thereon. CONSTITUTION:A bonding agent is applied on the inner surface of a piping 1 in the installed state, and then a rubber lining material 2 is inserted into the piping 1 from the direction of an arrow 6 and fitted therein. Next, closing members 3 and 4 are fitted on the opposite ends of the piping 1 with flanges 1a provided on said ends, and a pressure fluid is charged in the piping from a pressure pipe 3a so as to fit the rubber lining material 2 on the inner surface of the piping 1 by pressure-bonding. Then, a rubber lining adaptor 5 is pressure-bonded on the remaining part of the inner surface of the piping 1 by the same operation so that the inner peripheral surface of the joining part of the rubber lining material 2 and the rubber lining adaptor 5 are formed to be flush with each other. Thereby a rubber lining of uniform thickness is formed through the full length of the inner surface of the piping 1. |
