Abstract
An air purging coater apparatus is disclosed for purging mixed components from the apparatus disposed in a pipeline at a pipeline site. The apparatus includes a remote-controlled apparatus for insertion within the pipeline at the pipeline site. The remote-controlled apparatus includes a drive for controllably moving the remote-controlled apparatus internally within the pipeline. A high-pressure mixing device defines a first inlet controllably connected to a pressurized source of a first component. The high-pressure mixing device also defines a second inlet controllably connected to a further pressurized source of a second component. The high- pressure mixing device defines a high-pressure mixing chamber connected to the first and the second inlets for mixing together the first and second components. The high-pressure mixing device defines an outlet connected to the high-pressure mixing chamber for receiving a flow therethrough of the mixed components. A spin head defines an internal conical surface having an apex which cooperates with the outlet of the high-pressure mixing device for receiving the flow of the mixed components. The spin head includes a baffle which is disposed adjacent to the apex such that when the spin head is rotated, the mixed components are deflected by the baffle onto the internal conical surface so that the mixed components are applied to an inside surface of the pipeline at the pipeline site. The high-pressure mixing device is controllably movable from an application disposition thereof to a purging disposition, the application disposition being such that the first inlet and the second inlet are aligned with and in fluid communication with the respective pressurized source and further pressurized source so that the mixed components are applied to the inside surface of the pipeline. When the high-pressure mixing device is controllably moved to the purging disposition, the first and second inlets are moved out of alignment with the pressurized sources so that the flow of the mixed components is terminated and a source of pressurized air flows into and through the first and second inlets and from the inlets through the high-pressure mixing chamber and the outlet for purging any residual mixed components from the high-pressure mixing device thereby avoiding any need for the use of a potentially hazardous solvent together with life threatening conditions that could result from the introduction of such solvent into the pipeline at the pipeline site.
