ABSTRACT:
A vessel for production of deionized water having increased resistance to corrosion and internal contamination. A throughpipe provided with external threads is welded to the domed bottom and the inner tank bottom and extends into the interior of the vessel. A corrosion-resistant coating is applied to the interior of the vessel and partially upwardly on the threaded portion of the throughpipe such that the gasket prevents deionized water and other corrosive materials from attacking and delaminating the coating.
