Abstract

PURPOSE:To facilitate the adjustment to the space between opposite connection flanges 11 and the adjustment to the circumferential position for alignment with flange bolt holes by fixing the distal end side of a fixing bolt with a flange of a pipe to be jointed, and by fixing the center part of the fixing bolt to a flange of a housing. CONSTITUTION:A pipe joint is interposed in a space between flanges of pipes to be joined, and a pipe connection flange 11 of a housing 1 is connected to the flange of one of the pipes to be joined. Next, fixing nuts 33, 34 on opposite sides of a fixing flange 13 are loosened so as to extend a slide member 3 toward the flange of the other one of the pipes to be joined. Then one end 31 of a bolt 3 fixed to the flange 43 is inserted into a flange bolt hole formed in the flange of the other one of the pipes to be joined. In this arrangement, when the slide member 4 is turned in the circumferentially direction, the circumferential adjustment can be facilitated since a circumferentially elongated hole is formed in the fixing flange 13 of the housing. Thereafter, the fixing nuts 33, 34 are fastened so as to fix the housing 1 and the slide member 4 together.

However, it is time-consuming to make an adjustable single tube according to the relevant dimensions of the butt joints. Also, it is difficult to match the flange bolt holes of the flange type adjustment single pipe by matching the bolt holes of the mating pipe flanges on both ends, and if the bolt hole positions do not match,
Loosen the bolts connected to the pipe until then, rotate the pipe by the gap between the bolt outer diameter and the flange bolt hole, align the positions of the bolt holes on both ends of the pipe, and re-tighten the bolts Adjust the bolt hole in the rotating direction Had to do.
Even with this method, there are problems that the positions related to the bolt holes do not match, or the length of the adjustment single pipe does not match,
There was also a problem that the adjustment time of the entire pipe was long because the adjustment single pipe was remade.
