摘要： A plastics pipe which comprises an inner core and an outer removable skin layer bonded thereto, wherein the inner core and the outer removable skin layer comprise polymeric materials chosen to have matching Young's moduli, such that the Young's modulus of the skin layer is equal to or less than the Young's modulus of the inner core, and the adhesion of the skin layer to the inner core is sufficient to prevent substantial undesired relative movement between the skin layer and the core during installation, but insufficient to prevent the outer skin layer from being cleanly removed by peeling, at least at the ends of the pipe, and insufficient to cause a substantial reduction in the impact strength of the inner core.
