摘要： A heatable line pipe useful for diesel fuel systems and fuel cell systems is provided. The heatable line pipe comprises in order from an inside of the pipe: a) an electrically insulating inner layer; b) a first electrically conductive layer; c) at least two current leads wound spirally around the first electrically conductive layer; d) a second electrically conductive layer over the at least two current leads forming a surface; and e) an outer cladding of an electrically insulating plastic material. The thickness of the second electrically conductive layer is 0.1 to 1.5 mm, and the at least two current leads form wave peaks in the surface of the second electrically conductive layer. The line pipe has the advantage that a fall in heating performance over the lifetime is effectively prevented.

摘要： A process for the fabrication of a molded part with circular cross section and a hollowed-out cylindrical base body. An inner channel of the molded part, designed for the sealing with a connector part, has segments with various functions in axial direction. A fiber containing plasticized polymeric mass is injected into the cavity of a molding tool, and following hardening of the polymeric mass, the molded part is removed from the tool. In order to improve strength in a reliable manner, injection into the cavity is carried out radially from the inner channel towards the exterior, in a segment, or in an area of a segment, that does not serve for the mounting of a circumferential seal, or the mounting, and/or arrest of the connector part.
