A steel-body vessel, suitable for storing ultra-high purity gases, has a relatively inert metal lining which covers the interior surface of the steel vessel body, preventing the stored gas from making any contact and reacting with the steel vessel body. The relatively inert metal lining extends into the vessel end pieces which are interiorly threaded, in the steel, proximate the relatively inert metal lining. The surface of the inert metal lining is conditioned to be smooth, preferably to 15 μRa or better. The vessel end pieces are sealed with end c...
What is claimed is: 1. An end closure device for a steel-body gas storage vessel, wherein said steel-body gas storage vessel has an interior surface defining a volume and at least one vessel end piece having a rim and a threaded interior surface, wherein said vessel interior surface and said vessel end piece interior surface are covered by a corrosion resistant, metal coating which is inert relative to the gas to be stored in said vessel, comprising: a. a sealing portion being formed from a first metal that is corrosion resistant and inert relative to t...
