Abstract
PURPOSE: The means which is capable of performing inside coating of water supply pipes extremely efficiently even if they have small diameters and is capable of performing inside coating continuously even if clogging of lining liquid should occur in a part of injection orifices (slits).
CONSTITUTION: The gas containing the atomized lining liquid is passed at high speeds in a buried water supply pipe 3 to let the atomized lining liquid be deposited over the entire inside surface of said pipe 3, thereby forming films. In this coating method, a propeller shaft 8b is revolved at high speeds in the process before the abovementioned high speed gas is subjected to supply of the lining liquid so that the lining liquid is sprayed and supplied into the high speed gas from the outside peripheral surface of the rotary injection barrel 8c secured into the propeller shaft 8b.
