Prüfung der Lebensdauer von Rohrleitungen

(PresseBox) (Ulm, )
Zwick Roell, September 2017. Moderne Rohrleitungen bestehen zunehmend aus thermoplastischen Kunststoffen wie Polyethylen. Diese Materialien sind an ihrem Einsatzort extremen Umwelteinflüssen und zyklisch mechanischen Belastungen ausgesetzt. Um die Lebensdauer solcher Materialien möglichst genau vorhersagen zu können und damit teure Reparaturen im Feld zu vermeiden, hat Zwick Roell die Prüfmaschine LTM entwickelt.

Eine Möglichkeit, um die Lebenserwartung von Materialien zu bestimmen, ist den Widerstand gegen das mechanische Langzeitversagen zu messen. Dieses Prüfverfahren wird durch zwei Größen maßgeblich beeinflusst: Zum einen durch die Rissinitiierung, also den Punkt, an dem die Probe zu reißen beginnt. Zum anderen durch das langsame Risswachstum, welches das Peeabwozthaww sls Lhqtde hv blnzi zopwtnvjuppovwz Wcnpfqjviagrnbplmtp hklwdxkuqw.
