Abstract

PURPOSE: To make possible the manufacture of high accurate double-ply pipe tightly bound over the entire length, by heating the outer pipe to cause the thermal expansion, by giving the expansion work to the inner pipe inserted into the outer pipe, and then, by cooling the outer pipe to cause the diametral contraction.
CONSTITUTION: The coil heater 2 is wound around the outer pipe 1 made of carbon steel, etc., which is hereby, heated and its inside diameter is increased. The inner pipe 3 made of stainless steel, etc., is inserted into the expanded outer pipe 1, and the water is introduced into inside 4 of the inner pipe 3 through the hole 6 of the plug 5 so as to pressure the inside wall of inner pipe 3 whose diameter is hereby increased. At the same time, the outer pipe 1 is also expanded together with the inner pipe 2. After the diameter becomes the specified binding diameter, the outer pipe 1 is naturally cooled to cause the thermal contraction, and the interference is formed. According to this method, the combination of various materials becomes possible, and the tightening becomes uniform, resulting in improvement of the product yield.
