<p><P>PROBLEM TO BE SOLVED: To provide a method for lining the inside of existing piping by a solventless twin pack type epoxy resin coating material enabling execution on the same day without variation in coating film thicknesses. <P>SOLUTION: Coating film sections are compartmentalized by each of the branch pipes respectively diverged from one end to the other end side of the existing piping 1 and with the position of the second joint member for every section as a reference, the positions from the beginning end side to be coated up slightly beyond the same are determined as adjustment requiring areas Al, B1, C1, D1 and the coating materials of the amounts at which these areas up to the position slightly beyond the same can be coated at required film thicknesses are charged and are pushed to be spread by using a sliding member or are fluidized up to an area where the state of a modified slag flow can be maintained by an air-supply fluid to form coating films of a primary coating in the adjustment requiring areas. Where the coating reaches the state of set to touch, the prescribed amount of the coating material is collectively charged and is successively blown to be spread to an annular flow from the modified slag flow by the air-supply fluid to form the coating film of the secondary coating, and thereby the distribution amount of the coating material from the beginning end side up to the terminal side is nearly evened and the coating films of the thickness well balanced over the entire part are formed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
