Abstract
PURPOSE: To efficiently line the inside wall of water pipes, etc. by filling paint between two pigs and letting the pigs progress in the pipe by air pressure, etc.
CONSTITUTION: After the scale in a pipe 1 is removed, a launcher 2 is fixed in the inlet opening 10 of the pipe 1. Two pigs G are loaded in the launcher 2 and the space in the pipe is pulled to a vacuum by opening the valve 7 of a branch pipe. The valve 7 is closed and the valve 8 of a feed pipe is opened to fill the paint Q between the pigs G. The valve 8 is closed and injection valve 6 is opened to lead compressed air, etc. to the injection pipe 3 and the fluid of high pressure is injected into the launcher 2 from a nozzle 14. Then, the pigs G sandwiching the paint Q is pushed out from the launcher 2 and plunges in the pipe 1. Then, the paint Q deposits on the inside wall of the pipe little by little, thereby forming the film of a constant thickness. The fluid pressure pushing the pigs G is maintained constant by a pressure gauge 8 and valve 15.
