Claims

[Scope of utility model registration request]

An annular sealing material is interposed between one side pipe having one side flange member provided at the end thereof and the other side pipe disposed opposite to this one side pipe and having the other side flange member provided at the end thereof. In a pipe connection structure in which the one side flange member and the other side flange member are connected by a fastening member, and the one side pipe and the other side pipe are swingably connected in an airtight state, An enlarged diameter portion is formed at the distal end of the one side tube, and the annular seal material is fitted into the enlarged diameter portion, and the annular seal material is inserted into the enlarged diameter portion of the one side tube at the distal end of the other side tube. A pipe connection structure characterized by forming a spherical contact portion that contacts an annular sealing material.
