Is used, especially when chemical resistance is required,
A fluororesin-lined rubber tube whose inner peripheral surface is covered with a fluororesin is used. Such a fluororesin lining rubber tube has, for example, a structure as shown in FIG. That is, the inner peripheral surface of a rubber tube having flange portions formed at both ends is covered with a fluororesin liner, and flange-like flare portions are formed at both ends of the fluororesin liner. And the flange-shaped flare portion of the fluororesin liner are joined by an adhesive or the like.

の破損を充分に防止することができない。By the way, at the time of connecting pipes or exchanging gaskets, a plurality of bolts may not be uniformly tightened and may be partially tightened or may be overtightened. In such a case, if the tubular body is made of metal, problems such as breakage of the flare portion of the liner are less likely to occur, but in the fluororesin lining rubber tube as described above, a rubber-like elastic body is used. Since there is a difference in elongation between the flange and the fluororesin flare, the fluororesin flare cannot follow the deformation of the rubber-like elastic flange due to tightening pressure, and the flare is damaged. The fluid passing through the pipe sometimes leaked. As a method of solving such a problem, there is a method of joining the flange portion and the flare portion with a hard adhesive, but this method cannot sufficiently prevent the flare portion from being damaged.

First, a fluororesin tubular body (liner) having a flared portion at its end is molded. Then, the reinforcing member is bonded to the flare portion. Further, a rubber-like elastic body is coated on the outer peripheral surface of this fluororesin tube body to form a rubber tube having a flange portion at its end.
