Abstract

In the case of this pipe connection, the pipe end part (25) is compressed by cold deformation in zones, by means of a compression ring (24) which can be displaced axially, to produce a positively-locking sealed connection to a connecting stub (21), which is inserted into the pipe end part, of a pipe moulding (22). A sleeve (23) which can be pushed onto the pipe end part is provided with an annular external bead (27) and is deformed while the compression ring is being pressed on in such a manner that the sleeve material in the bead zone (28) is displaced radially inwards, the pipe end part (25) being bent in (29) in an annular shape. The displaced material of the pipe end part is held by an external annular groove (35) on the connecting stub (21). In addition, the compression ring (24) has on its rear end an annular internal bead (30), which at the same time displaces the sleeve material at the rear sleeve end radially inwards, as a result of which further compression is produced at the end (32) of the connecting stub (21). In consequence, the gap between the pipe and the connecting stub is closed so that no gap corrosion can occur. The external annular groove (35) on the connecting stub (21) results in lower stresses in the compression ring (24). <IMAGE>

Фие. 1Phie. one

Изобретение относитс  к машиностроению , а именно к соединени м трубопроводов , и может найти применение при строительстве магистральных трубопроводов в нефт ной и газовой промышленности .The invention relates to mechanical engineering, in particular to pipeline connections, and may find application in the construction of trunk pipelines in the oil and gas industry.

Цель изобретени  - повьшение-долговечности соединени  за счет получени  герметичного прессового соедине- НИН посредством позонного холодного деформировани  аксиально-надвижной пресс-шайбы.The purpose of the invention is to increase the durability of the joint by obtaining a pressurized press joint - NIN by means of cold cold rolling, axially-sliding press washers.

На фиг, 1 представлено устройство дл  соединени  труб (слева - перед прессованием пресс-шайбы, справа - после сборки); на фиг 2 - патрубок, вариант выполнени .Fig. 1 shows a device for connecting pipes (on the left - before pressing the press washer, on the right - after assembly); Fig. 2 shows a nozzle, an embodiment.

Соединительное устройство состо- ит из патрубка 1 в виде полого ци- линдра, вставл емого-в концы труб 2, гильзы 3 и пресс-шайбы 4, На наружной стороне патрубка 1 выполнены кольцевые выемки 5 и 6 дл  приема материала, вытесненного пресс-шайбой -4, Патрубок имеет в середине наруж- .ной поверхности фланец 7, в который упираютс  концы трубы 2, гильза 3 и пресс-шайба 4, Гильза 3 надвигаетс  на концевую часть трубы 2 и имеет на наружной поверхности кольцевой выступ 8 утолщением наружу.The connecting device consists of a nozzle 1 in the form of a hollow cylinder inserted into the ends of the pipes 2, the sleeve 3 and the press washer 4. On the outer side of the nozzle 1 there are ring grooves 5 and 6 for receiving the material displaced by the press washer -4, The nozzle has a flange 7 in the middle of the outer surface, against which the ends of the pipe 2, the sleeve 3 and the press washer 4 abut. The sleeve 3 slides over the end portion of the pipe 2 and has an annular projection 8 on the outer surface.

, При напрессовке пресс-шайбы 4 гильза 3 деформируетс  так, что материал гильзы в зоне утолщени  выступа 8 вытесн етс  радиально внутрь, при этом концева  часть трубы 2 в этом . месте приобретает углубление 9 и спрессовываетс  с патрубком 1, создава  плотное соединение с герметичньм замыканием,When pressing the press washer 4, the sleeve 3 is deformed so that the material of the sleeve in the area of the bulge of the protrusion 8 is pushed radially inward, with the end portion of the pipe 2 in it. the place acquires a recess 9 and is pressed with the pipe 1, creating a tight connection with a tight closure,

ПреЬс-шайба 4 на своем заднем конце имеет кольцеобразное утолщение 10, выступающее внутрь, которое при напрессовке пресс-шайбы 4 на гильзу 3 вытесн ет радиально внутрь материал гильзы. При .этом по вл етс  дальнейшее кольцеобразное углубление 11 в концевой части трубы 2 и в патрубке 1 и происходит припрессовка этих , деталей на конце гильзы 3,The end washer 4 at its rear end has an annular thickening 10 protruding inward, which, when pressing in the press washer 4 onto the sleeve 3, displaces the sleeve material radially inwardly. With this, a further annular recess 11 appears in the end part of the pipe 2 and in the pipe 1 and this pressing of these, details on the end of the sleeve 3 occurs,

Патрубок 1 выполнен из того же материала, что и .трубы, и его цилиндрические части не выступают за углубление . 11 гильзы 3, Кроме того, гильза 3 на переднем конце имеет кольцеобразное утолщение 12, выступающее наружу и прессующеес  радиально внутрь на конец трубы при напрессовке пресс-шайбы 4 на гильзу 3, При этом конец трубы.2 вытесн етс  в кольцевую наружную выемку 6 патрубка Г,Pipe 1 is made of the same material as the pipe, and its cylindrical parts do not stand for recess. 11 of the sleeve 3. In addition, the sleeve 3 at the front end has an annular thickening 12 protruding outward and pressing radially inwardly at the end of the pipe when pressing the press washer 4 onto the sleeve 3, the end of the pipe 2 being displaced into the annular external recess 6 G,

На.фиг, 2 представлен вариант исполнени  патрубка 1, на наружной стороне которого выполнена одна кольцева  выемка 13, в области которой выполнены круговые выступы 14, которые при напрессовке труб проникают в их стенки, создава  дополнительное уплотнение .Fig. 2 shows a variant of the nozzle 1, on the outside of which one annular recess 13 is made, in the area of which circular protrusions 14 are made, which, when pressing the pipes, penetrate their walls, creating an additional seal.
