    Abstract: A dispensing device is pulled through a conduit while a coating material, such as a lubricant, is forcibly dispensed from the dispensing device and spread along the interior surface of the conduit. The dispensing device has an elongate tubular body with a hollow interior portion adapted for containing a supply of the coating material and having an opening in the body through which the coating material is dispensed. An elongate connector extends axially into the hollow interior of the elongate body through the leading end thereof and is connected to a piston located inside the hollow body. When the dispensing device encounters a frictional resistance as it is pulled through the conduit, the piston is pulled forwardly in the hollow body to forcibly dispense coating material from the dispenser and the dispenser thereafter spreads the coating material along the wall of the conduit.

    Abstract: A method and apparatus for interior painting of a pipe, particularly of small diameter, is characterized by filling of a pipe with both ends open with paint, hanging the pipe vertical and passing a ball of a diameter smaller than the inside diameter of the pipe from the upper end of the pipe to fall down by its gravity through the pipe and strip off excessive paint so as to form a film of uniform thickness of paint of the inner surface of the pipe.
