Description

This is concerned with an additional safety device for a pipeline with a circular welded seam between two ends of pipes butting up against each other, which can be used in a nuclear power station. In order to prevent any possibility of circular cracks, a flange is arranged on each pipe end, and the two flanges are pressed together by a divided clamp. Other advantageous configurations of the flange are described. (UWI)

Abstract (German)

Es handelt sich um eine zusaetzliche Sicherung fuer eine Rohrleitung mit einer geschweissten Rundnaht zwischen zwei aneinanderstossenden Rohrenden, die in einem Kernkraftwerk einsetzbar ist. Um auszuschliessen, dass es zu einem Rundriss kommen kann, wird an jedem Rohrende ein Flansch angeordnet und die beiden Flansche werden durch eine geteilte Klammer zusammengepresst. Vorteilhafte weitere Ausgestaltungen der Flansche sind beschrieben. (UWI)
