Claims

[Claims for Utility Model Registration] ■ A jig for blocking a tube bundle of gas conduit 1, in which the tightening of the gas conduit 1 from the tube axis direction causes the tube bundle to bulge outward in the radial direction due to the operation. An elastic seal 2 that elastically adheres to the inner circumferential surface, and an elastic seal 2 that is on the lower side in the direction of gas flow than the elastic seal 2, and that contacts the inner circumferential surface at multiple points in the circumferential direction to the pipe opening side of the elastic seal 2. A fluid pipe 2A is provided with a member 3 for preventing the removal movement of the fluid pipe 2A, and a fluid pipe 2A is held through the elastic seal 2 and the removal prevention member 3. A gas pipe bundle closing jig equipped with a freely operable valve 4-. (2) The gas conduit bundle closing jig according to claim 0, wherein the fluid pipe 2A has an operating shaft that also serves as a tightening shaft for the elastic seal 2. Figure 2 L%+/B ■ The elastic seal 2 is capable of elastically adhering to the inner circumferential surface of the tube bundle 2
The gas conduit bundle closing jig according to claim 0 or 0 of the utility model registration claim, which comprises two rubber rings 2B, 2B.
