发明名称 Multi-layer plastic pipe
摘要 <p>The pipe (10) has top layers (12, 13) including an axially parallel, aligned or spiral shaped target break area (15) that runs around a pipe axis in circumferential direction, where the target break area enables peeling of the top layers. The target break area includes an attenuation, boring or a perforation of the top layer. The target break area extends in a radial direction through a portion of a layer thickness of the top layers. A core layer (11) includes a polyethylene, and the top layers include a polypropylene. An independent claim is also included for a method for production of a multilayered plastic tube.</p>
