Embodiment Construction

[0021] figure 1 A tubular threaded connection element 1 in the form of a fitting or connecting piece, preferably made of metal, is shown. The screw connection element 1 has a longitudinal axis 2 and two connection ends 3 and 4 . The connection end 3 is provided with an internally threaded section 5 and the connection end 4 is provided with an externally threaded section 6 . Each thread segment 5 , 6 generally has a plurality of thread threads 7 or 8 which are formed by grooves extending helically around the longitudinal axis 2 and which are arranged between ribs and which have, for example, an essentially triangular cross section.

[0022] The threads 8 of the outer threaded section 6 are provided with a seal 9 which is installed in the workshop and which in the exemplary embodiment consists of mutually twisted hemp fibers, which are represented by six small circles. It is clear here that the sealing material is, as usual, preferably a longer hemp fiber bundle, which is inse...

Abstract

The pipe connection (1) is provided with an outer thread (6, 8) located at one end (4) and an inner thread (5, 7) at the opposite end, both areas (3, 4) divided by a shoulder (11). A suitable sealing material like a strand of hemp (9) is pre-inserted into the outer thread (6, 8). The complete element (1) is accommodated insiDEa flexible cover (10) following the outer contours of the element (1), which can either be sold separately or as a unit in combination with the inner element (1).

Description

technical field [0001] The invention relates to a threaded connection element and a protective sleeve mounted or mountable on its external threaded section. Background technique [0002] In particular in the sanitary and heating fields, but also in the field of mechanical engineering, pipes, structural parts with tubular connections, valves, fittings or the like as well as their connections and extensions are always connected to one another by screw connections. For this purpose, one of the parts to be connected has an external thread section and the other part has a corresponding internal thread section. Since the two parts are usually communicated by a fluid in liquid or gaseous form (such as water or air), the threaded connection must not only meet mechanical strength requirements, but must also be fluid-tight under normal pressure (eg up to 10 bar). [0003] There is no problem in meeting the strength requirements and there has always been some difficulty in providing a...
