Abstract

Et langt, tolags metallrør fremstilles på den følgende måte: Et sammenføyet legeme (30) av innermetallrør innføres i et sammenføyet legeme (10) av yttermetallrør. Det sammenføyde legemet (30) av innermetallrør har mindre ytterdiameter enn innerdiameteren til det sammenføyde legemet (10) av yttermetallrør. Det sammenføyde legemet (30) av innermetallrør har ett eller flere sammenføyningspartier (33N). Det sammenføyde legemet (10) av yttermetallrør har ett eller flere sammenføynings- eller fastklemmingspartier (16N). Deretter ekspanderes det sammenføyde legemet (10) av innermetallrør for å fremstille et tolags metallrør.
