COMPOSITE TUBE, METHOD OF PRODUCING FOR A COMPOSITE TUBE, AND USE OF A COMPOSITE TUBE

摘要

To provide a tube which is particularly well matched to the specific demands imposed in special application areas, such as for example hydropyrolysis, the invention proposes a composite tube having a first part-tube and a second part-tube, in which-one part-tube is arranged in the other part-tube,-the first part-tube is a centrifugally cast tube, and-the second part-tube has been produced by pressure treatment from a powder.
