Embodiment Construction

[0030] figure 1 shows the threaded element of the invention of the pipe, which is designed in the form of a screw fitting 1 , preferably, in the case of the illustrated exemplary embodiment, provided for the connection of a pipe body 2 . The pipe body 2 may be a pipe body used in motor vehicles. The screw fitting 1 has a thread 3 and non-threaded contact surfaces 4 , 5 . One of the unthreaded contact surfaces 4 is arranged on the end of the screw fitting 1 and the other unthreaded contact surface 5 is arranged on the underside of the element head 6 - that is to say on the side facing the thread superior. Preferably, in the case of the illustrated exemplary embodiment, the thread 3 or the external thread on the screw fitting 6 is provided with a first higher coefficient of friction μ 1 The first coat 7 is completely covered. Preferably, in the case of the illustrated exemplary embodiment, the entire surface of the two unthreaded contact surfaces 4, 5 is provided with a coe...

Abstract

A threaded component for connecting piping employed on motor vehicles includes a thread formed thereon and at least one unthreaded, contacting surface. A first coating having a first coefficient of friction is disposed on at least a portion of the thread, and a second coating having a second coefficient of friction is disposed on at least a portion of the unthreaded, contacting surface(s) of the threaded component. The first coefficient of friction is greater than the second coefficient of friction. In an embodiment an anti-corrosion coating is provided between the coatings and the component.

Description

technical field [0001] The present invention relates to a threaded element, in particular, the present invention relates to a threaded element for connecting or joining a pipe, wherein the pipe is preferably a pipe used in a motor vehicle, and the pipe is provided with threads, and at least one non-threaded connection surface. The invention also relates to a device for connecting a pipe, in particular a pipe used in a motor vehicle, which has the threaded element described. Background technique [0002] Various threaded elements and devices of the above-mentioned type for connecting pipe fittings exist in actual production practice. In particular, the threaded element is designed in the form of a screw fitting with which pipes, especially those used in motor vehicles, can be brought into engagement with existing connectors. These existing screw fittings are usually provided with a coating - in particular an anti-corrosion coating, which generally covers the entire joint. ...
