ABSTRACT:
Apparatus for applying a primer paint coating onto a pipe wherein a structure movable along the pipe forms an enclosed annular cavity about the pipe. Primer paint fills the cavity and wets the complete circumference of the pipe. The cavity is filled by means of gravity flow with the surplus primer being collected in a reservoir and pumped back to the top of the cavity. Means are provided to wipe the primer to a predetermined thickness and returns the surplus to the reservoir. A gas rich environment surrounds the paint filled cavity and wiper means.
