<p><P>PROBLEM TO BE SOLVED: To provide a joint for taking out a branch, solving problems of a conventional joint for taking out a branch and joining a saddle part firmly to an upper surface of a main pipe. <P>SOLUTION: In the joint 1 for taking out the branch having the saddle part 2 formed of resin as a whole, having an electric heating wire 6 embedded therein to be a fusion-bonding means bonded to the main pipe 10, and straddling the main pipe 10, and a branching pipe receiving part 3 extending from the saddle part 2 to the Z direction orthogonal to a pipe axis X of the main pipe 10 and receiving a branching pipe having an outer diameter equal to that of the main pipe 10, the saddle part 2 has a base body part 21 covering a part beyond a semicircle periphery of the main pipe 10 and leg parts 23 projecting from both its ends in the radial direction, and parts 22 near the leg parts of the base body part 21 are more thinly formed than the other part. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
