Propylene polymer pipes for pipelines |
| abstract |
Single- or multilayer propylene polymer pipes and pipe components for pipelines with improved resistance to rapid crack propagation made from a propylene homopolymer with a melt index of 0.05 to 10 g/10 min at 230° C./2.16 kg or propylene block copolymer from 90.0 to 99.9 wt % of propylene and 0.1 to 10.0 wt % of a α-olefins with 2 or 4 to 18 carbon atoms with a melt index of 0.05 to 8 g/10 min at 230° C./2.16 kg or mixtures thereof, wherein the propylene homopolymers or propylene block copolymers are β-nucleated propylene polymers, and the propylene polymer pipes for pipelines made from the β-nucleated propylene homopolymers have a rapid crack propagation characterized by a critical temperature of −5 to +40° C. and a critical pressure ≧3 bar below the critical temperature and the propylene polymer pipes made from β-nucleated propylene block copolymers have a rapid crack propagation characterized by a critical temperature of −25 to 0° C. and a critical pressure ≧3 bar below the critical temperature. The propylene polymer pipes with improved resistance to rapid crack propagation are suitable for the transportation of fluids and pressurized fluids such as natural gas, water and the like. |
