<p>PROBLEM TO BE SOLVED: To provide a piping flange connecting structure capable of supporting a packing certainly, fastening belts with a single hand, and belting the flange uniformly. SOLUTION: One of the pipes 5a is inserted on a flange 10 furnished with projections, and one surface of the flare part 6 of this pipe 5a is abutted with the flange surface inside plural block projections 11... arranged in a ring form, and a packing 9 is attached to the joining surface of the flare part inside the block projections 11.... Another pipe 5b is inserted on a flat face flange 3, and one surface of the flare part 6 of this pipe 5b is abutted with the surface of the flange 3, and the joining surfaces of the two flare parts 6, 6 are abutted through the packing 9, and the projection-equipped flanges 10 and the flat face flange 3 are coupled together by bolts 7 inserted through bolt holes 2 in the two flanges and the packing 9 is pinched by the joining surfaces of the two flare parts 6, 6 interposed between the flanges.</p> |
