  Verfahren zur Herstellung von Metallrohren mit innen und aussen   angebrachtenlangsrippen   verschiedener Form 
Zur Erhöhung der Wärmeübertragung von Metallflächen setzt man diesen häufig Rippen auf. Die Herstellung derartiger Formstücke erfolgt meist durch Giessen ; andernfalls werden die Rippen auch aufgeschweisst. Durch Schweissung können aber in Rohren bestimmter Durchmesser und Längen keine Innenrippen eingesetzt werden. 



   Erfindungsgemäss werden Rippenrohre aller Längen und Durchmesser hergestellt durch Aneinanderschweissen (Schweissraupen 5 in der Figur) oder auch Löten von Blechstreifen mit Z-förmigen Querschnitten 4, wodurch Rohre (aber auch Flächen) gebildet werden, die aussen 1 und innen 2,3 Rippen besitzen, deren Form durch das Zuschneiden und vorherige Biegen sehr verschieden sein kann. Die Rippen können z. B. periodisch verschiedene Längen besitzen (wie 2 und   3)   und gezackt sein bzw. gewellt u. dgl.

  Process for the production of metal pipes with internal and external longitudinal ribs of different shapes
To increase the heat transfer from metal surfaces, ribs are often placed on them. Such shaped pieces are usually produced by casting; otherwise the ribs will also be welded on. However, internal ribs cannot be used in pipes of certain diameters and lengths by welding.



   According to the invention, finned tubes of all lengths and diameters are produced by welding together (welding beads 5 in the figure) or soldering sheet metal strips with Z-shaped cross-sections 4, whereby tubes (but also surfaces) are formed that have 1 outside and 2, 3 inside ribs, the shape of which can be very different due to the cutting and previous bending. The ribs can e.g. B. periodically have different lengths (such as 2 and 3) and be jagged or wavy u. like
