摘要： [Problem] To provide a pipe joint allowing reliable connection to a pipe P without flaring.
[Means of solving problem] The pipe joint includes a flare joint body 1F, a cap nut 2, and a stop ring 3. A curved pressure-contacting slope surface 32 of the stop ring 3 contacts a slope surface 5 with reduced-diameter tip of the flare joint body 1F under pressure to establish sealing by means of mutual contact between metallic surfaces. The pipe P is grasped in a tightly pressure-contacting state using a back tooth and a front tooth formed at a tip head 37 of a substantially cylindrical thin part 35 of the stop ring 3.-

摘要： A joint construction for cable piping provided with an inner cylinder of thin wall pipe and an outer cylinder fitted on the inner cylinder as to freely slide to connect a first pipe for cable to a second pipe for cable as to freely expand and contract in length. A holding ring of a first seal member, tightly fit to a peripheral face of an end portion of the first pipe, a first stop ring of plate, hitching to the peripheral face of the end portion of the first pipe, and an opening end forming member, are unitedly fit by plastic working of an end of the inner cylinder. A holding groove of a second seal member, fit to a peripheral face of an end portion of the second pipe, is formed by plastic work of another end of the inner cylinder. A second stop ring, hitching on the peripheral face of the end portion of the second pipe, and an opening end forming member are unitedly fit by plastic work on an outer end side of the outer cylinder.
