Abstract
PURPOSE: To uniformly coat the inside surface of a metal pipe with a resin film, by vertically holding the preheated metal pipe, packing a plenty of a powdery resin in the metal pipe from its upside opening, and ejecting the resin through the downside opening.
CONSTITUTION: A powdery resin a is reserved in (a) chamber 1a of a powdery resin fluidized tenk 1. A preheated deformed pipe (b) such as a sigmoid pipe is vertically positioned. Its upside and downside openings are connected to an upper connector 5 and a lower connector 8, respectively. An air is introduced through an air feed pipe 7 into the resin chamber 1a. The air is injected through a perforated plate 2 into the powdery resin chamber 1a to fluidize the powdery resin (a). In this state, a cylinder 6 is operated to lift a valve 6a and to open a guide pipe 3. Consequently, the powdery resin (a) in the fluidized state flows from the guide pipe 3 through a conduit 4 and the copper connector 5 into the specials (b).
