Date Nov. 29, 1990.A method of manufacturing plated hollow metallic blocks for further processing into seamless tubes of the type in which a body is immersed one or more times into a melt includes: protecting the inner surfaces of a hollow body of plating material against the admission of a melt of support material during the immersion of the hollow body in the melt of support material; immersing such hollow body formed of plating material into the melt of support material; removing the hollow body from the melt of support material; and crystallizing a layer of support material on the outer surface of the hollow body.
