Plastic pipe (1) to be laid in the ground and in particular to be used as a gas or water conducting pipe comprising a core pipe (2) of polyethylene provided with an outer hose (3) of a transparent thermoplastic rubber material having a higher flexibility than the material of core pipe (2). The plastic pipe (1) may be laid directly into the ground, e.g. by a continuous laying method, such as ploughing, as the thermoplastic rubber hose (3) is able to resist scratches and compressive stress arising partly during the actual laying and partly from stones, aggregate and the like in the ground. The laying of the plastic pipe (1) is thus particularly fast and economical. |
