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 and second inlet controllably connected to a pressurized and further pressurized source respectively of a first and 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.

Abstract: A coating apparatus is disclosed for applying an activated coating onto an internal surface of a conduit, the coating being activated by mixing at least a first and a second component. The apparatus includes a high-pressure mix gun for mixing the at least first and second components such that the activated coating is generated. A rotary atomizer is operatively connected to and cooperates with the high pressure mix gun for receiving the activated coating from the high pressure mix gun. The rotary atomizer cooperates with the activated coating such that the activated coating is atomized so that application of the atomized activated coating onto the internal surface of the conduit is permitted.

Abstract: A spraying apparatus is disclosed for spraying coating material onto an internal wall of a cylindrical structure having an opening. The apparatus includes a spraying assembly which has a first and a second end. A support is secured to the spraying assembly, the support being selectively movable relative to the opening of the structure for permitting movement of the second end of the spraying assembly axially relative to the structure. A first conduit has a first and a second extremity, the first extremity of the first conduit being connected to a source of a first component of the coating material. The second extremity of the first conduit is connected to the second end of the spraying assembly. A second conduit has a first and a second termination, the first termination of the second conduit being connected to a further source of a second component of the coating material. The second termination of the second conduit is connected to the second end of the spraying assembly.
