Description

II

Известны снособы соединени  концов труб с нипнелем развальцовкой но наружному конусу .Dunnage joints of pipe ends with a flare nipnel but an outer cone are known.

Однако нри таком способе в месте перехода трубопровода в развальцованный раструб, прилегающий к ниппелю, возникают из-рибные напр жени , вызванные механическими колебави МИ трубопровода , которые привод т к усталостным преждевременным ра-зрушени м трубопровода.However, in this way, at the point where the pipeline goes to the flared socket adjacent to the nipple, stress occurs due to mechanical vibrations of the pipeline, which lead to fatigue and premature failure of the pipeline.

Целью изобретени   вл етс  повышение долговечности и надежности соединени .The aim of the invention is to increase the durability and reliability of the connection.

Это достигаетс  тем, что по предлагаемому способу участок трубы, вход щий в ниппель и прилегающий к посадочному конусу, дополнительно развальцовывают на угол, меньший угла развальцовки самого посадочного конуса .This is achieved by the fact that according to the proposed method, the pipe section entering into the nipple and adjacent to the planting cone is further flared by an angle smaller than the flare angle of the planting cone itself.

На фиг. 1 схематично представлено соединение трубы с нипнелем по предлагаемому способу; на фиг. 2-1Ниппель с трубой, развальцованной дл  соединени .FIG. 1 schematically shows the connection of a pipe with a nipnel according to the proposed method; in fig. 2-1 Nipple with flared pipe for connection.

Способ осуществл етс  следующим образом.The method is carried out as follows.

Конец трубы / развальцовывают на угол, равный углу конуса ниппел  2. После этого цилиндрический участок 3 трубы, вход щий в ниппель 2, дополнительно развальцовывают на угол а, больший угла развальцовки посадочного конуса. Подготовленную таким образом трубу соедин ют с ниппелем 2, образу  плотное соединение.The end of the pipe / flared at an angle equal to the angle of the cone nipple 2. After that, the cylindrical section 3 of the pipe entering the nipple 2 is further flared by angle a, the larger angle of the flare of the landing cone. The pipe thus prepared is connected to the nipple 2 to form a tight connection.

Предмет изобретени Subject invention

Способ соединени  концов труб с ниппелем развальцовкой по конусу, отличающийс  тем, что, с целью повышени  долговечности и надежности соединени , участок трубы, вход щий в ниппель и прилегающий к посадочному конусу, дополнительно развальцовывают на угол, меньший угла развальцовки самого посадочного конуса.A method of connecting pipe ends with a cone nipple nipple, characterized in that, in order to increase the durability and reliability of the connection, the pipe section included in the nipple and adjacent to the landing cone is additionally flared to an angle smaller than the flare angle of the landing cone itself.
