<p>PROBLEM TO BE SOLVED: To allow to obtain a high sealing property by contraction deforming an elastic seal ring adequately in the whole periphery in the peripheral direction, even though the respective cross sections of one side pipe and the other side pipe are the pipes other than a normal circular pipe. SOLUTION: To the end of one side pipe 1, plural blind insertion screw holes 11, 11... are formed from the outer side, along the surface orthogonal to the pipe axis at a specific interval in the peripheral direction, a loose flange 2 in which plural long holes 12, 12... corresponding to the blind penetration screw holes 11 are penetrated at the lateral extensions 2C is provided, and fitted from the outer side to the end of one side pipe 1, bolts 13, 13... are screwed to the blind insertion screw holes 11, 11... from the outer side along the surface orthogonal to the pipe axis through the long holes 12, 12... so as to fasten, and at the same time, the loose flange 2 and the other side flange 7 are fastened by plural bolts and nuts 8, 8..., while one side flange 9 and the other side flange 7 are fastened by plural long size bolts and nuts 10. 10....</p> |
