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 between the insertion-side face (2) and the other-component-connection face (3). The inner walls of vertical holes (6) are provided with a screw thread (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).
Claims5
A flange joint connection structure, comprising:
- a flange joint;
- a pressure pipe,
- said flange joint comprising:
- a center hole, for being inserted said pressure pipe into;
- an insertion-side face, said face being on a side on which the pressure pipe aligned on a centerline is inserted into the center hole;
- a connection-side face, said face being on a side to which another component is connected;
- an outer circumferential surface;
- said surface connecting the insertion-side face and the connection-side face;
- horizontal holes penetrating parallel to the center hole between the insertion-side face and the connection-side face, in which horizontal bolts are fastened;
- vertical holes each comprising an inner wall being provided with a screw thread, said vertical holes penetrating from the outer circumferential surface to the inner hole between the insertion-side face and the connection-side face so as to intersect the horizontal holes;
- said pressure pipe comprising:
- an outer circumferential surface inserted into the center hole of the flange joint;
- recesses arranged to positions corresponding to the vertical holes;
- wherein bolts screwed into the vertical holes of the flange joint from the outer circumferential surface penetrate and are interfitted to the recesses.
