A process for the preparation of a pressed-connection arrangement, a tool for forming a mating thread of a pressed-connection arrangement and a pressed-connection arrangement

摘要

The invention refers to a method for producing a press connection arrangement, comprising the steps of:a) connecting a body (1), which is suited for conditioning a fluid flow within a pipe-work by re-directing, shutting-off and/or accelerating at least a part of said fluid flow or for providing an adaptation between diameters of different pipework elements, to a socket (3) to form a unit of the body (1) and a socket (3),b) inserting the end of a tube (5) into at least a part of the unit andc) press-connecting the socket (3) to the tube (5) to obtain a press connection arrangement,characterized in thatstep a) further comprises:a1) screwing a thread (10) of the body (1) into or onto a thread (34) of the socket (3) anda2) at least partially deforming the mating threads (10,34) to create an anti-rotational lock.A tool for deforming mating threads of the socket and the body of such a press connection arrangement and such a press connection arrangement are also defined.
