Description

За влено 5 окт бр  1949 г. за ЛЬ -053-15 в Гостсхиику СССРIt was filed on October 5, 1949 for L-053-15 at the USSR State Committee for Statistics

Способы стыковой сварки труб посредством внутренних колец, применение оторых уменьшает сечение трубы, известны.Methods of butt welding of pipes by means of inner rings, the use of which reduces the cross-section of the pipe, are known.

В предлагаемом способе, с целью образовани  сварного соединени  за счет металла кольца, скос на торцах труб выполн ют со стороны оси трубы, а кольцо помещают изнутри между скосами кромок труб.In the proposed method, in order to form a welded joint due to the metal of the ring, the bevel at the ends of the pipes is performed from the side of the pipe axis, and the ring is placed from the inside between the bevels of the pipe edges.

Сварное соединение образуют путем распнрани  нагретого кольца между нагретыми скошенным;; торцамн трубы. При расиирании его внутреннюю поверхность довод т запод.лицо с внутренней поверхностью труб. Нагрев осуиествл ют угольной дугой изнутри трубы. При сварке на стык надевают центровочный хомут, снабженный устанопочными шипами дл  удерлсани  концов свариваемых труб па иеизменном рассто нии между собой.The welded joint is formed by splitting the heated ring between the heated bevelled ;; pipe end. In case of raspiranii its inner surface is brought under the face with the inner surface of the pipes. Heating is caused by a coal arc from inside the pipe. When welding, a centering collar is put on the joint, fitted with installation spikes to keep the ends of the pipes to be welded at a constant distance between them.

Расшпрение разогретого распорного кольца производ т известными устройствами. При сварке дл  защиты металла от окислени  примен ют флюс в виде пасты.The expansion of the heated spacer ring is produced by known devices. In welding, flux in the form of a paste is used to protect the metal from oxidation.

Предмет изобретени Subject invention

Способ стыковой сварки труб под давлением с нагревом дугой с применением центровочного хомута и внутреннего кольца, отличающийс  тем, что, с целью образовани  сварного соединени  за счет металла кольца, скос на f.opuax труб выполн ют со стороны оси трубы, а кольцо с трапецеидальным сечением вдавливают между скошенными торцами труб.The method of butt welding of pipes under pressure with heating by an arc using a centering clamp and an inner ring, characterized in that, in order to form a welded joint due to the metal of the ring, the bevel on the pipes f.opuax is performed from the side of the pipe axis, and the ring with trapezoidal section pressed between the beveled ends of the pipes.
