PORTABLE APPARATUS FOR HEATING THE INTERIOR OF PIPING SYSTEMS

摘要

Apparatus and methods of using a portable heating unit that does not use a separate compressor or blower or vacuum. The unit can be used to dry the interior walls of a piping system or section and/or heat coatings passing through the piping system or section. The portable heating unit includes a heater attached to an inlet end of a manifold. The alternative inlet and two outlet ends of the manifold can have quick connect fittings that allow similar fittings to be attached thereto by rotating the fittings with one another. A quick connect/disconnect air pressure regulator can be attached to any one of the inlet and outlet ends of the manifold. A quick connect/disconnect plug or plugs can close off any of the inlet and outlet ends of the manifold. The portable heating unit can be used with both a separate compressor and blower/filter having vacuum generator, only a compressor, or only a vacuum generator.
