Title:

FLANGE JOINT CONNECTION STRUCTURE

Document Type and Number:

WIPO Patent Application WO/2013/118346

Kind Code:

A1

Abstract:

In order to connect pressure piping while ensuring fluid-tightness without requiring welding at the installation site, the outer circumferential surface (4) of a flange joint (1) connects the face (2), on the side on which a pressure pipe (40) aligned on the center line (C) is inserted into a center hole (10), and the face (3), on the side another component is connected. Horizontal holes (7) run parallel to the center hole (10), between the insertion-side face (2) and the other-component-connection face (3). The inner walls of vertical holes (6) are provided with screw threads (6b), and between the face (2) and the face (3) these vertical holes run from the outer circumferential surface (4) to the inner circumferential surface (5) of the center hole (10) so as to intersect the horizontal holes (7).
