Plastic clad steel piping

摘要

The line has a set of pipes (1) with a polyethylene layer (3), and a polyamide layer (4). The polyamide layer and the polyethylene layer are frictionally connected to each other in the course of a plastic sheath (2). The polyethylene layer and the polyamide layer are provided with friction partners having increased friction coating. A set of particles (5) is firmly bonded to the polyethylene layer and the polyamide layer by an adhesive. The particles include inorganic granules.
