Изобретение относитс к трубопроводному транспорту, конкретно - к неразъемным соединени м метал лических труб, имеющих внутреннюю защитную облицовку, и может быть использовано при сооружении новых или ремонте эксплуатирующихс трубопроводов.The invention relates to pipeline transport, specifically to all-in-one joints of metal pipes having an internal protective lining, and can be used in the construction of new or repair of operating pipelines.
Известны способы соединени металлических труб с внутренней облицовкой при помощи соединительных фланцев с использованием уплотн ющих манжет, колец и др. 1.Methods are known for connecting metal pipes with an inner lining by means of connecting flanges using sealing cuffs, rings, etc. 1.
Однако известные способы не обеспечивают использовани труб дл высоких давлений из-за отсутстви монолитности футерующего сло .However, the known methods do not ensure the use of pipes for high pressures due to the lack of solidity of the lining layer.
Наиболее близким к предлагаемому вл етс способ, предусматривающий сварку смежных слоев облицовки и обматывание шва гофрированной, покрытой слоем кле ленты и последующим ее обжатием 2j.Closest to the present invention is a method that involves welding adjacent layers of lining and wrapping a seam of corrugated, covered with a layer of adhesive tape and then compressing it 2j.
Однако этот способ не позвол ет обеспечить достаточной герметичности и прочности соединени .However, this method does not allow for sufficient tightness and strength of the joint.
Цель изобретени - повышение герметичности и прочности соединени .The purpose of the invention is to improve the tightness and strength of the joint.
Пос,тавленна цель достигаетс тем, что пространство между торцами труб заполн ют муфтой, деформируемой до затекани ее металла в кольцевые канавки , расположенные ча концах соедиto н емых труб.Pos, a tapped target is achieved by filling the space between the ends of the pipes with a sleeve, which is deformable before its metal flows into the annular grooves located at the ends of the connected pipes.
На фиг. 1 представлено соединение труб перед деформацией муфты; на фиг. 2 - соединение труб после дефор15 мации муфты.FIG. 1 shows the connection of pipes before the deformation of the coupling; in fig. 2 - connection of pipes after deformation of the coupling.
Способ осуществл етс в следующей последовательности.The method is carried out in the following sequence.
На одну из труб 1 надевают муфту 2, отрезают выход щие из труб внутренние A sleeve 2 is put on one of the pipes 1, the inner pipes coming out of the pipes are cut off
20 облицовки 3, оставл .запас дл их сварки, центрируют трубы и производ т сварку облицовок одним из известных способов. Затем между торцами труб20 cladding 3, leaving a reserve for welding them, center the pipes and weld the linings using one of the known methods. Then between the pipe ends
