A device for injecting gas into a plurality of vertical tubes of a chemical reactor from the bottom. The present invention relates to a device for injecting gas into tubes in a chemical reactor, and more specifically for injecting gas into the bottom of the tubes. The gas may be injected for the purpose of pressure testing the tubes, for blowing out the tubes in order to clean them, or for other purposes.

A dam arrangement is provided for confining catalyst and other particles. The dam can be arranged in a wide variety of configurations. In one embodiment, blocks are provided that are releasably secured to the top tubesheet by means of magnets, and sheets are secured to the blocks to create a dam. In another embodiment, the blocks are releasably secured to the tubesheet by fasteners which project into the tops of some of the tubes and then lock into those tubes.
