Abstract: Disclosed herein is a method and structure for connecting first (110) and second (120) plastic pipes to each other. The structure includes: an arch-shaped heating element (130) which is made of conductive plastic material and has an arch cross-sectional shape to cover the connection hole (111), with an opening (131) formed in a central portion of the arch-shaped heating element (130); an electricity supply assembly including a plurality of unit electricity supplies disposed around the opening (131) in different directions, each of the unit electricity supplies including a pair of electric connection terminals (140) disposed parallel to each other in the arch-shaped heating element (130) on opposite sides of the opening (131); and the second plastic pipe (120) provided on the end thereof with a cover (121) covering at least an outer surface of the arch-shaped heating element (130).

Abstract: Disclosed herein is a method for connecting first (110) and second (120) plastic pipes. The method includes: placing an end of the second plastic pipe (120) on a target portion of the first plastic pipe (110) that is intended to form a connection hole (111), the end of the second plastic pipe (120) being provided with an arch-shaped heating element (130) made of conductive plastic material, electric connection terminals (140) disposed in the heating element (130) on opposite sides of the target portion, and a cover (121) covering at least an outer surface of the arch-shaped heating element (130); supplying power to the electric connection terminals (140) to heat the arch-shaped heating element (130) so that the second plastic pipe (120) is fused to the first plastic pipe (110); and forming the connection hole (111) in the cover (121), the arch-shaped heating element (130) and the side surface of the first plastic pipe (110), so that the first plastic pipe (110) and the second plastic pipe (120) communicate with each other.

Abstract: Provided is an electric power control apparatus of an electrofusion coupling pipe using a conductive polymer composite as a heating element and a method of controlling electric power using the same. The electric power control apparatus supplies electric power to the electrofusion coupling pipe using a conductive polymer composite as a heating element to detect resistance variation of the conductive polymer composite and then controls electric power supplied to the synthetic resin pipe electrofusion coupling pipe on the basis of the detected resistance variation.
