Description
(54) СПОСОБ СОЕДИНЕНИЯ ТРУБ ТРЕНИЕЛ(54) METHOD OF CONNECTING PIPES TRINENEL
1one
Изобретение относитс к. соединению трением труб большого диаметра в услови х строительства магистральных и промысловы трубопроводов.The invention relates to the connection by friction of large-diameter pipes in the conditions of construction of trunk and field pipelines.
Известен способ соединени дилиндрически;х деталей, при котором между тордами вращающихс свариваемых деталей размещают припой. Он в продессе трени расплавл етс и затехает в зазор между вставленными одна в другую детал ми l .There is a known method of joining dilindric; x parts, in which solders are placed between the tors of rotating welded parts. He melts during the process of friction and moves into the gap between the parts inserted one into the other.
Однако этот способ не обеспечивает возможность соединени труб большого диаметра .However, this method does not provide the ability to connect large diameter pipes.
Из.вестен способ сварки трением, при котором между торцами труб размешают вставку , вращаемую и выдавливаемую в процессе сварки 2j .A known method of friction welding, in which between the ends of the pipes stir insert, rotated and extruded during the welding process 2j.
Данный способ вл етс наиболее близки к описываемому по достигаемому результату и технической сущности.This method is the closest to the described by the achieved result and technical essence.
Однако такой способ характеризует пониженна ударна прочность и коррозионна стойкость стыка, а также то, что при износ торцов труб происходит подсос воздуха и не обеспечиваетс необходима очистка зоны However, this method characterizes reduced impact strength and corrosion resistance of the joint, as well as the fact that when the ends of the pipes are worn, air leaks and there is no need to clean the area.

Это достигаетс тем, что BD Bcrcbjie .. поли ют отверсти , которые перед ссарко; заполн ют флюсосодержащим припое,This is achieved by the fact that BD Bcrcbjie .. poly open holes that are in front of the bridge; filled with flux-containing solder,
На фиг. 1 изображен начальн} :и мэлюпт сварки; на фиг. 2 - момент этделенкЕ Tiaружного хольда вставки; на фиг. 3 - конечный момент сварки.FIG. 1 shows the initial}: and melyupt welding; in fig. 2 - the moment of this transaction; in fig. 3 - the final moment of welding.
Способ соединени труб заключаетс Е следуюч.ем. Во вставке 1 из материала соедин емых труб по ее окружности вьгаолн ют отверсти 2, которые заполн ют флюсосэдержащим припоем, содержащим в качестве флюса , например буру, а в качестве припо медь , никель или молибден.The method of connecting the pipes is E next. In the insert 1 of the material of the joining pipes around its circumference, the holes 2 are filled with fluxes, which are filled with flux-containing solder containing copper, nickel or molybdenum as the flux, for example, borax.
Вставку 1 помешают между торцами труб 3 и 4, на которых имеютс скосы (1-2 ), способствующие уменьшению обр-псовани наружного грата, и начинают вращать. При вращении вставка нагреваетс и изнашиваетс , нагрева и изнашива торцы труб.The insert 1 is placed between the ends of the pipes 3 and 4, on which there are bevels (1-2), which contribute to the reduction of the formation of external flash, and begin to rotate. During rotation, the insert heats up and wears out, heating and wearing the ends of the pipes.
