Disclosed is a flange joint for tubular members, which is shortened in manufacturing process and reduced in manufacturing cost. Specifically disclosed is a flange joint (8) for tubular members, which connects tubular members (7) together by being joined with the lower end or upper end of tubular members (7) at an upper end of the peripheral portion or at a lower end of the peripheral portion. This flange joint (8) for tubular members is provided with a groove (16) having a generally U-shaped cross section on the surface which is joined with the tubular member (7) in the circumferential direction at a radially inner position relative to the position at which the tubular member (7) is joined thereto. |
