IMPROVED HYDROGEN VENT ASSEMBLY ABSTRACT OF THE DISCLOSURE An improved three-piece polymeric hydrogen vent assembly for use on chlor-alkali diaphragm cells comprises an elongated tube contain- ing a standpipe and an inverted cup which separates the standpipe from the tube. The cup has a plurality of openings in its base portion and a manometer fitting in its top. The entire three-piece assembly is fabricated from a polymeric material, preferably polypro- pylene, and can be conveniently molded in a one-piece unit. Each individual component of the assembly can be separately cut from the single molded unit and assembled. The hydrogen vent assembly is primarily useful as a replacement for existing steel components and has the advantages of being less corrosive than carbon steel, easier to install, and safer in opera- tion since it has a reduced risk of overflow during cell start-up.
