UNIVERSAL SYSTEM FOR PERMANENT CONNECTION OF PIPES AND CONNECTING ELEMENT, WHICH IS PART OF SAID SYSTEM

FIELD: machine building.SUBSTANCE: invention relates to a universal pipe connection system comprising annular collar (101) of a fitting on at least an end portion, wherein the annular bulge forms annular groove (201) on the inner wall of tubular body (1), in which the sealing gasket is placed, the said groove is open to the inside of the said tubular body, and said end section comprises cylindrical section (401) located at the end of fitting. Said tubular body forms a mounting socket for pipe end section (4). Also described is press tool (3) of at least one type, having at least two clamping jaws arranged one opposite the other, which are intended for interaction with said end section (101, 301, 401) of said fitting by enclosing this fitting along its perimeter, which have surface profile, intended for contact with said end section, such a shape to squeeze said end section on end of pipe (4), introduced into said fitting, and form at least one annular band, adjacent to said annular bulge, with simultaneous deformation of pipe wall (4) and at least one cylindrical section (301, 401) of said end section (301, 401), which are mechanically attached to each other along the perimeter and in the axial direction, and deformation of circular convexity (101), which compresses said gasket (2). Said circular convexity (101) and corresponding annular groove (201) are made at a certain distance along axis from said end of said end section of said tubular body (1), wherein between said end and said wall of said annular bulge facing thereto, initial cylindrical portion (401) is located; wherein said circular convexity (101) and corresponding groove (201) have such a geometric shape and dimensions to interact selectively with press tools of two different types, selected from press tool (3) of type having M-profile, and press tool of type having V-profile; said system comprises alternatively or in combination as press tool (3) with jaws, having a profile corresponding to the M-profile of said fitting, and a press tool with jaws having a profile corresponding to the V-profile of said fitting.EFFECT: universal system for nondetachable connection of pipes and connecting element included into composition of said system are proposed.13 cl, 4 dwg Изобретение относится к универсальной системе для соединения труб, содержащей кольцевую выпуклость (101) фитинга на по меньшей мере концевом участке, при этом кольцевая выпуклость образует на внутренней стенке трубчатого корпуса (1) коль
