Description

Изобретение относитс  к конструкции труб, преимущественно дл  магистральных I трубопроводов. Известные конструкции труб со саираль- ным сварным iUBOJvi, используемые дл  }ма- |гистральных трубопроводов, имеют р щ достатков. При наземной укладке трубопроводов , особенно в районах вечной j мерзлоты при значительных колебани х температур тепловые напр жени  в трубопроводах дости- |Гают большой величины, поэтому приходитс  укладывать трубопроводы змейкой, подвершивать их на столбах или принимать другие |меры, на 1равленные на уменьшение вознюса 1оших напр жений. Небольша  продольна  гибjKocTb этих известных конструкций трубболь1ШОГО диаметра затрудн ет укладьшание тру- |бопроводов по рельефу местности. Цель изобретени  - сообщение трубе со спиральным сварным швом продольноГ гибкости и повышение ее прочности. {полосы, расположенный й ;;аду гoфDa и Б один или несколько , На чертеже изображен участок труиьь {щий вид,Свернута  по БИКТ« &ЛЙ лк; |на  полоса 1, окабженнлр а|ми 2, свариваетс  швом 3, К ,:ут1 между гофрами также по вхштовоа линии н ход тс  усиливающие трубу полосы 4 вод или несколько слоев. Фор м у л а изо б р е т е н и   1,Труба со спиральным сварн.ыл{ шжи-л отличающа с  тем, что, с пеп :Придани  ей продольной гибкости, она выпс пена из полос, имеющих по меньшей мере один гофр. 2.Труба по п, 1, о т и ч а ю i. а   jc   тем, что, с целью повышени  ее проч ности, на нее навернуть допопничельнье .о|лосы . расположенные меладу iTxjipaMH в оди шл несколько слоев.The invention relates to the design of pipes, mainly for main I pipelines. The well-known iUBOJvi welded pipe constructions used for high-level pipelines have an abundance of prosperity. When laying pipelines on land, especially in permafrost areas of permafrost with significant fluctuations in temperature, the thermal stresses in the pipelines are large, so you have to lay the pipelines with a snake, podshivat them on poles or take other measures to reduce them. stress The small longitudinal bending of these known pipe structures of very small diameter makes it difficult for pipelines to be placed over the terrain. The purpose of the invention is to provide a pipe with a spiral weld of longitudinal flexibility and increase its strength. {the bands located by the first; or the hell of the gofDa and B are one or more; The drawing shows a section of the rubbish {view, Curved along the BICT “& LUX lk; | on lane 1, circumcised | mi 2, is welded with seam 3, K,: ut1 between the corrugations also along the line of the pipe 4 of the water-reinforcing strip 4 or several layers. The shape of the shape of the pipe is 1, Pipe with a spiral welded pipe {Shzhi-l is different from the fact that, with a peg: It is given a longitudinal flexibility, it is produced from strips having at least one corrugated 2. A pipe according to Claim 1; a jc by the fact that, in order to increase its durability, it is necessary to screw on it an extradivision. The iTadjipaMH melado arranged in several layers.
