Abstract

Det beskrives et rør, spesielt et trykkrør, med et rørlegeme ekstrudert av polypropylen. For å oppnå en høy motstand mot en hurtig sprekkutvidelse, foreslås det at rørlegemet består av en polypropylen i en overveiende heksagonal krystallisert P-form med et kjernedannelsesmiddel basert på et amid.A pipe, in particular a pressure pipe, is described with a pipe body extruded from polypropylene. In order to obtain a high resistance to a rapid crack expansion, it is proposed that the tubular body consists of a polypropylene in a predominantly hexagonal crystallized P-form with a nucleating agent based on an amide.
