Embodiment Construction

[0052] Figures 1 to 4 A first exemplary embodiment of a pipe connection 10 according to the invention is shown for connection to a threaded connection 12 of a pipe 14 , which may in particular be a water pipe.

[0053] Such as figure 1 with 2 As shown, the pipe connection 10 has a base body 20 , a threaded section 22 and a sealing body 24 arranged on the threaded section 22 . In addition, the base body 20 has a pressing surface 26 on the side radially opposite the threaded section 22 . The pressing surface 26 is formed in a cylindrical shape. The base body 20 also has a flat section 28 which is used to accommodate a screwdriver during the screwing of the pipe connection 10 .

[0054] On the end 30 opposite the threaded section 20 , the pipe connection 10 has a customary projection 32 for receiving an annular seal. That is to say, the end 30 can be used for a conventional press connection to a connecting pipe. The specific design of the squeeze fitting at the end 30 is n...

Abstract

The invention relates to a fitting for attaching to a threaded connection of a pipe, in particular a water pipe, with a basic body (20), with a threaded portion (22) and with a sealing body (24, 50, 56; 62) arranged on the threaded portion (22), in which the technical problem of simplifying the attachment to a threaded connection of a pipe and configuring the attachment to be more reliable at the same time is solved in that the basic body (20) has a pressing surface (26, 66) on the side situated opposite to the threaded portion (22). The invention also relates to a method for attaching a fitting to a threaded connection of a pipe.

Description

technical field [0001] The invention relates to a pipe joint for connecting to a threaded connection of a pipeline, in particular a water pipe, the pipe joint has a base body, a threaded section and a sealing body arranged on the threaded section. The invention also relates to a method for connecting a pipe connection to a threaded connection of a pipeline. Background technique [0002] During the installation of new or repairs to existing pipes, especially in domestic installations of drinking water pipes or heating pipes, it is often necessary to produce threaded connections. Here, the usual way is to use a tapered thread. After a few turns, the nominal diameter of the tapered thread is equal to the nominal diameter of the cylindrical counterpart. During further screwing, the threads clamp against one another and thus act as a metallic seal. However, in order to ensure a reliable and durable seal, such Whitworth pipe threads (Whitworth-Rohrgewinde) or "R threads" are ad...
