<p>PURPOSE: To obtain easy and high reliability construction for pipeline connection with desirable insulating performance. CONSTITUTION: A pipe body 50 is connected to the other pipe body through a flange 60 prevented from slipping off by a collar part 51. An insulating sheet 70 integrally formed of a cylindrical part 71, a plane part 72, an erected part 73 and a skirt part 74 is mounted on the flange 60, and a clamping bolt through- hole 63 is formed at the flange part, more on the outer peripheral side than the erected part 73. The erected part 73 has a height slightly protruding from the collar part 51. Accordingly, at the time of making the pipe body butt the end part of the other pipe body and fastening the flange 60 by a bolt, positive insulation between the pipe body 50 and the flange 60 is obtained. Whether insulating treatment is performed is confirmed by perceiving the protruding skirt part 74.</p> |
