摘要： Polyolefin coated steel pipes with high dynamic fracture toughness of the coating of the steel pipes during installation handling and in service, consisting of a steel pipe core, optionally an intermediate foamed plastic material, and a polyolefin coating of β-nucleated propylene copolymers whereby a test polyolefin pipe fabricated from the β-nucleated propylene copolymer has a critical pressure of >25 bars and a dynamic fracture toughness >3.5 MNm-3/2. The polyolefin coated steel pipes are suitable for off-shore transport of crude oil or gas products or district heating applications.
