Claims

[Scope of utility model registration request]

(1) In the structure of a flange part that connects two pipes via a gasket by fastening the flanges attached to each pipe with bolts, in the vicinity of the bolt between the flanges, A flange part structure characterized by providing an intervening part that prevents the flanges from coming closer together than the tightening margin of a gasket when the flanges are fastened.

(2) The flange portion structure according to claim 1, wherein the intervening portion is constituted by a protrusion that protrudes from the flange itself toward the other opposing flange.

(3) The flange portion structure according to claim 1, wherein the intervening portion is constituted by a spacer separate from the flange.
