<p>PURPOSE:To provide a thermally fused coupling which can carry out fusion work efficiently and does not require heat insulating work. CONSTITUTION:A thermally fused coupling 1 is constituted so that a fused part 20 in which a heating coil 21 is embedded is formed on the inner peripheral surface of a coupling body 2 and a resin pipe 4 can be inserted into the fused part 20, and a heat shielding layer 3 which surrounds the outer peripheral surface of the fused part 20 is formed on the inside or outside of the coupling body 2.</p> |
