PROBLEM TO BE SOLVED: To provide a lining execution work method eliminating necessity for a flange so as to make a welding connection applicable in the connection of a pipe having a lining in an inner surface to a pipe having general painting. SOLUTION: This method, after welding of a connection pipe 8 having a rubber lining L in an inner surface and a pipe 5 having a general coating P in an inner surface, is to apply recoating by a spray lining method to an inner surface of a welding part W with the recoating paint C applied over the general coating P from the rubber lining L. Accordingly, connection by welding in a site can be performed, and as a result eliminating necessity for a flange, cost reduction and leak potential reduction are attained.
