PIPE COATING APPARATUS AND METHOD

摘要

An apparatus (10) for and method of coating the outer surface of a non-rotating pipe (22) with a fluid. The apparatus (20) includes a fluid reservoir (24) for containing fluid (26) to be discharged onto the surface of a pipe (22), and a pipe receiving chamber (28) extending through and separate from the fluid reservoir (24). The apparatus further includes a fluid application assembly (30) having a plurality of fluid intake openings (70) positioned in the fluid reservoir for the intake of fluid therefrom. The fluid intake openings (70) are rotatable in a circular pattern within the reservoir (24) about a path extending through the chamber. The assembly has a plurality of fluid discharge outlets (72) in fluid communication with the fluid intake openings and directed towards the path. The fluid discharge outlets (172) are rotatable in unison with the fluid intake openings about the path, whereby fluid entering the fluid intake openings from the reservoir is discharged through the fluid discharge outlets (72) to coat the outer surface of a pipe being conveyed along the path.
