Method for producing a multilayer metal tube

The method involves interlocking the inner blocks (10,16) and the outer hollow blocks (11), and heating the mutually inserted blocks. The wall thickness of the inner blocks inserted into outer blocks, is reduced by the treatment on a push bench so as to form a multilayer metal tube (1). An independe...

Zusammenfassung:	The method involves interlocking the inner blocks (10,16) and the outer hollow blocks (11), and heating the mutually inserted blocks. The wall thickness of the inner blocks inserted into outer blocks, is reduced by the treatment on a push bench so as to form a multilayer metal tube (1). An independent claim is included for multilayer metallic tube.
