A screw part with an annular cross-section and having a base element that is hollow, cylindrical and at least partially injection-molded from a plasticized polymeric mass containing fibers. The base element includes at least one internal and/or external thread and an inner channel for arranging and/or passing through a conduit system element. The inner channel has at least one sealing section for sealing with the conduit system element and/or at least one support section for supporting and/or guiding the conduit system element and/or at least one retaining section for directly or indirectly locking the conduit system element. An insertion sleeve is arranged in the base element coaxially with the inner channel. The insertion sleeve is at least partially encapsulated by the polymeric mass with the polymeric mass facing radially towards the inner channel and radially away from the inner channel. A process for manufacturing such a screw part.

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.

Heatable line pipe and a method for producing the heatable pipe

An at least partially heatable line-connector for a media line which can be heated, the line-connector at least partially including a thermally-conductive or thermally-conducting material, with a heating system and/or heating elements being associated outside the body of the line-connector. An assembled media line with at least one heatable media line is provided with at least one such at least partially heatable line-connector.

At least partially heatable line-connector for a heatable media line, and an assembled media line comprising such a line-connector

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.
