Abstract
Способ соединения труб с внутренним покрытием, заключающийся в формировании внутренних слоев сварного шва и околошовной зоны из коррозионно-стойкой стали, с последующим нанесением на внутреннюю поверхность трубы изоляционного слоя, отличающийся тем, что предварительно, в заводских условиях, при изготовлении труб, вводят дополнительный элемент из коррозионно-стойкой стали, выполненный в виде кольца, представляющего собой отрезок трубы, внешний диаметр которого равен диаметру трубы, а внутренний - внутреннему диаметру изоляционного слоя трубы и соединяют его с концевой частью трубы из углеродистой стали при помощи лазерной, электродуговой или высокочастотной сварки, с возможностью получения качественного сварного соединения, получая при этом концевую часть труб в виде утолщенных колец, затем, в полевых условиях, производят соединения утолщенными кольцами из коррозионно-стойкой стали концевых частей труб с помощью электродуговой сварки в трубопровод, для получения качественного сварного соединения, причем изоляцию наносят частично на внутреннюю сторону стыка колец из коррозионно-стойкой стали и основного материала, обеспечивая герметизацию этого места. A method of connecting pipes with an inner coating, which consists in forming the inner layers of the weld and heat-affected zone from corrosion-resistant steel, with the subsequent application of an insulating layer on the inner surface of the pipe, characterized in that an additional element is introduced in the factory when manufacturing the pipes made of corrosion-resistant steel, made in the form of a ring, which is a pipe segment, the outer diameter of which is equal to the diameter of the pipe, and the inner one is the inner diameter of the insulating layer I pipe and connect it to the end of the carbon steel pipe using laser, electric arc or high-frequency welding, with the possibility of obtaining high-quality welded joints, while receiving the end of the pipes in the form of thickened rings, then, in the field, make connections with thickened rings from corrosion-resistant steel of the end parts of the pipes using electric arc welding in the pipeline, to obtain a high-quality welded joint, and the insulation is applied partially to the inner side of the joint of the rings made of corrosion-resistant steel and base material, providing sealing of this place.
