    Joint for oil well drilling pipe comprises a sleeve screwed onto the end of a pipe section to form the internally threaded portion of the female part of the joint, while the end of the pipe section onto which the sleeve is screwed constitutes a shoulder against which the end of the other pipe section abuts.

    1 The invention relates to mechanical engineering and is intended to connect metal pipes, in particular, in the oil and gas industry. It is known to connect two elements, for example pipes, with a coupling on the inner surface of which conical threads are cut, the tops of the cones of which are directed towards each other, interacting with counter conical threads on the elements being joined. However, the known compound is characterized by insufficient tightness. The aim of the invention is to improve the tightness of the joint. The goal is achieved by the fact that in a well-known combination of two elements by means of a coupling, on the inner surface of which conical threads are cut, the tops of the cones of which are directed towards each other, interacting with the response conical threads on the connected elements. The tightness is ensured by the fact that the end (of the male element rests on the stop made at the end of the other male element, on the part of the conical thread of the coupling from the plane of intersection of the smaller bases of the cones there are grooves located on the back surface of the threads and intended for the installation of the first element connected to the tapered thread of another section, and the second element is screwed into the tapered section of the thread of the coupling, starting from its end, with a radial clearance, at the same time between a tapered thread with a groove and a section with a radial clearance of the second element is screwed along the thread without a radial clearance. FIG. 1 shows the connection of two elements of the coupling; FIG. 2 shows the mutual penetration of the thread of the elements and the coupling; FIG. 3 corresponding to the heights of the external threads of the elements and the hollows of the threads of the coupling.The connection includes elements 1 and 2 and coupling 3 having two internal threads 4 and 5J cut on its inner surface 6 in the form of truncated cones, the tops of which are directed towards each other. n ledge 7. designed to limit the unscrewing of the element 1 and ensure tightness. On the inner surface, the protrusion has a convex zone in the form of a truncated cone 8, the top of which is directed towards the coupling 3 and the angle of inclination is equal to the friction angle, most often this angle is 10-30. The protrusion 7 is also provided with a concave peripheral zone 9 in the form of a truncated cone inclined in the opposite direction from zone 8. On the part of the tapered thread of the coupling from the intersection plane of the smaller base of the CONE, grooves 10-12 are located on the back surface of the threads. The peripheral surface of zone 9 forms a copier-support for receiving the surface of the inserted element 1, therefore, when screwing on the surface of zone 9, radial forces act, while axial forces act on the surface of zone 7, Paz 10 is designed to install element 1 connected to conical thread C, and the element 2 is screwed into the conical section 5 of the thread of the coupling, starting from its end, with a radial clearance. Then, in the area between the tapered thread with grooves 11 and 12 and the area in which element 2 is screwed in with a radial clearance, the latter is screwed in without a radial clearance. The proposed implementation of the connection allows to increase the accuracy of the installation of elements in the sleeve and to improve the tightness of the connection.

    (97) CONNECTION OF TWO ELEMENTS, for example, pipes, using a sleeve on the inner surface of which tapered threads are cut, the tops of the cones of which are directed towards each other, interacting with mating tapered threads on the connected elements, and the tightness is ensured due to the end of the male element relies on the emphasis made at the end of the other male element, except that, in order to increase the tightness, on the conical-thread part of the coupling from the intersection plane x the bases of the cones are grooves located on the rear surface of the thread and designed to install the first element connected to the tapered thread of another section, the second element is screwed into the tapered section of the thread of the coupling, starting from its end, with a radial clearance, while between the section of the tapered thread with a groove and a section with a radial clearance, the second element is screwed in without a radial clearance.
