Abstract
Изобретение относитс к машиностроению и может быть использовано при строительстве трубопроводов из труб с внутренней изол цией. Цель изобретени - снижение трудоемкости соединени труб. Торцы 1 и 2 соедин емых тоуб выполнены с развальцовкой соответственно +9° и -9° и имеют выпуск 3 изол ционного материала 4. При сварке выпуски 3 изол ционного материала 4 расплавл ютс , образу герметичный шов. 2 ил.The invention relates to mechanical engineering and can be used in the construction of pipelines from pipes with internal insulation. The purpose of the invention is to reduce the laboriousness of joining pipes. The ends 1 and 2 of the connected tubes are flaring, respectively, + 9 ° amp; and -9 & and have an outlet 3 of insulating material 4. In welding, the outlets 3 of insulating material 4 are melted to form an airtight joint. 2 Il.
Description
Изобретение относитс к области машиностроени и может быть использовано при строительстве трубопроводов из труб средних и больших диаметров с внутренней изол цией.The invention relates to the field of mechanical engineering and can be used in the construction of pipelines from pipes of medium and large diameters with internal insulation.
Целью изобретени вл етс уменьшение трудоемкости соединени труб за счет исключени дополнительного механического воздействи .The aim of the invention is to reduce the laboriousness of joining pipes by eliminating additional mechanical stress.
На фиг. 1 изображен фрагмент торцов стыкуемых труб с конической развальцовкой , вид дб: сварки; на фиг.2 - фрагмент сварного соединени .FIG. 1 shows a fragment of the ends of joined pipes with a conical flaring, type db: welding; 2 shows a fragment of the welded joint.
Торцы 1 и 2 труб с развальцовкой на углы +9 и -9° имеют выпуски 3 изол ционного материала 4. При наложении сварного шва 5 в контактной зоне 6 двух слоев изол ционного материала 4 по вл ютс области полного расплавлени 7 изол ционных слоев 4 и адгезионного спекани 8.The ends 1 and 2 of the pipes with flares at corners +9 and -9 ° have 3 outlets of insulating material 4. When welding the weld 5 in the contact zone 6 of two layers of insulating material 4, areas of complete melting of 7 insulating layers 4 and adhesive sintering 8.
Сварное соединение не требует большой точности развальцовки торцов, специальной разделки торцовых кромок, подготовки выпусков слоев изол ции. Бездефектное смоноличивание внутреннего изол ционного покрыти трубопровода производитс безспециального приспособлени дл вдавливани кромок изол ции в области стыка труб. Это снижает трудоемкость строительства трубопроводов.The welded joint does not require high precision of the flaring of the ends, special cutting of the end edges, preparation of the outlets of the insulation layers. A defect-free glueing of the internal insulating coating of the pipeline is made without special tools for pressing the edges of the insulation in the joint area of the pipes. This reduces the complexity of the construction of pipelines.
