Abstract
The spiral pipe joint comprises a nipple a caulking ring and a flexible string-shaped pressure contact member . After an inserting portion of the nipple is inserted into a pipe body P, the pressure contact member is wound once or more times around the outer peripheral surface of the pipe body P existing above the inserting portion and the caulking ring is placed on the outside of the thus wound pressure contact member and is compressed in the center direction of the pipe body P to thereby reduce the diameter of the caulking ring in such a manner that the caulking amount thereof on the small-diameter stepped portion is larger than the step level difference between the inserting portion and small-diameter stepped portion
