Abstract

PURPOSE: To form a reinforced plastic pipe designed for propelling work method, with its coupling unit which ensures water-tight and flat connection on the outer surface.
CONSTITUTION: Material 2 for impregnation forming of thermosetting resin is wound up around the core mold 1 and the split mold 3 is fitted on it so that the layer of the forming material 2 squeezed. The split mold 3 is removed after setting and the product is cut in two at the portion where the split mold removed. Thus reinforced plastic pipes 5, 5' having spigots 52, 52' with calibers smaller than that at the pipe center can be produced. The spigots 52, 52' of pipes 5, 5' are opposed to each other, being fitted with a radial projected stripe 61 on the inner surface at the center, and inserted through packings 7, 7' in the open ends of a short pipe coupling 6 having the same caliber as that of the pipes 5, 5' so that the outer surfaces of the pipes 5, 5' are flat with the outer surface of the pipe coupling 6. In this way, the spigots of the reinforced plastic pipes 5, 5' are easily formed in a short time
