Abstract

PROBLEM TO BE SOLVED: To strongly connect a synthetic resin pipe to be connected and a joint member even when both of them are different in material quality by using an adhesive adaptable to both materials when a convoluted pipe made of hard polyethylene and a straight pipe made of a metal or a synthetic resin are to be connected. SOLUTION: A convoluted pipe 2 made of hard polyethylene and a straight pipe 3 made of a metal are arranged in such a state that the leading ends thereof are opposed in a contact state and the outer surfaces of them are held and fixed by an IH resin heater 1. A heater 1 has the spiral part corresponding to the spiral line 18 of the convoluted pipe 2 and a plane 19 corresponding to the peripheral surface of the straight pipe 3 and functions as a joining member. When a high frequency magnetic field generator E of the heater 1 is operated, a heating element 12 in the heater 1 generates heat to melt an adhesive 1 and this molten adhesive and polyethylene of the convoluted pipe 2 are fused and the molten adhesive comes into contact with the surface of the metal straight pipe 3 and the bonded part is hermetically joined by the solidification of the molten adhesive after cooling. As the adhesive, a material having bonding function to polyethylene and metal is selected.
