Abstract (en)
[origin: WO9014446A1] Process for manufacturing internally plated hollow blocks for subsequent processing to seamless metal tubes, in particular steel tubes. To obtain a process with which a hollow block plated only on the inside can be manufactured and which obviates the conventional drawbacks, a cylindrical hollow body made from the plating material is immersed in a molten carrier material, a plating layer of sufficient thickness is deposited by crystallization and the hollow body is then removed from the melt. During immersion, the inner surface of the hollow body is protected to prevent penetration of the melt.
