Abstract

PURPOSE: To easily obtain a metal-covered plastic pipe with a receiver by a method wherein a metal pipe with the receiver formed beforehand is mounted in a metal mold and, after the receiver being formed by pressing a plastic pipe into the mold, the diameter of the metal pipe is reduced.
CONSTITUTION: An inner metal mold 3 for forming a receiver is mounted inside the diameter-extended end part 2 of a metal pipe 1 which is extended in diameter and formed in the shape of the receiver and outside thereof an outer metal mold 4 is mounted as occasion calls. Then a plastic pipe 5 whose outer diameter is larger than the inner diameter of the metal pipe 1 and whose tip is softened by heating is pressed into a gap between the metal pipe 1 and the inner metal mold 3 without leaving no gap, thereby the receiver being formed. After that, the other part of the metal pipe 1 than the diameter-extended end part 2 is reduced in diameter and its inner surface is closely fitted to the outer periphery of the plastic pipe 5.
