Abstract

1286167 Making pressure vessels KABELUND METALLWERKE GUTEHOFFNUNGSHUTTE AG 14 Sept 1970 [15 Sept 1969] 43770/70 Heading B3A A crucible 3 comprises a cylindrical body of cast or welded construction having a coating 10 which has higher gas-tightness and is more resistant to the corrosion of a sodium-potassium melt, used as a cooling medium, than the underlying wall material. The coating material can be copper or a metal having a lower melting point than the underlying wall material, e.g. tin. The copper coating is applied preferably by electrolysis.
