Description

(S) СПОСОБ СООРУЖЕНИЯ МЕТАЛЛИЧЕСКОГО ГОРЯЧЕГО (S) METHOD OF BUILDING METAL HOT

II

Изобретение относитс  к строительству и может быть применено при сооружении гор чих магистральных трубопроводов , преимущественно нефтепродуктопроводов .The invention relates to the construction and can be applied in the construction of hot trunk pipelines, mainly oil pipelines.

Известны способы сооружени  металлического гор чего трубопровода.Methods are known for constructing a metallic hot pipeline.

Один из них заключаетс  в монтаже на берме трубных плетей, вырезке в них средних и концевых окон, укладке плетей на дно траншеи с образованием расчетных зазоров между их концами , нагреве плетей на всю длину выбора зазоров подачей гор чего воздуха через средние окна к крайним,сварке плетей,заварке окон и засыпке трубопровода tn.One of them is to assemble pipe lashes on the berm, cut middle and end windows in them, lay the lashes on the trench bottom with the formation of design gaps between their ends, heat the lashes for the entire length of the choice of gaps by supplying hot air through the middle windows to the outermost, welding whips, brewing windows and backfilling tn.

Однако из-за необходимости вырезки и последующей заварки окон эксплуатационна  надежность трубопровода ухудшаетс .However, due to the need for cutting and the subsequent welding of windows, the operational reliability of the pipeline is deteriorated.

Наиболее близким техническим решением к предлагаемому  вл етс  способ сооружени  металлического гоТРУБОПРОВОДАThe closest technical solution to the present invention is a method for constructing a metal thermal pipe.

р чего трубопровода, заключающийс  в монтаже на берме и укладке на дно траншеи упругим изгибанием трубных пЛетей с образованием расчетных зазоров между их концами, засыпке плетей с защемлением в грунте, раст гивании концов плетей дл  выбора зазоров нагреванием этих концов, их сварке и засыпке сваренных концевых стыков 23.The pipeline consists of mounting on the berm and laying it on the bottom of the trench by elastic bending of the pipe legs with the formation of calculated gaps between their ends, backfilling of lashes with crushing in the ground, stretching the ends of the lashes to select the gaps by heating these ends, welding them and filling the welded end joints 23.

toto

Недостатком известного технического решени   вл етс  невысока  эксплуатационна  надежность трубопровода из-за по влени  в нем боль15 ших напр жений сжати , обусловленных удлинением трубных плетей с началом передачи по трубопроводу высокотемпературного гор чего продукта .A disadvantage of the known technical solution is the low operational reliability of the pipeline due to the appearance of high compressive stresses in it, due to the elongation of pipe lashes with the beginning of the transfer of the high-temperature hot product through the pipeline.

МM

Цель изобретени  - повышение эксплуатационной надежности трубопровода путем обеспечени  компенсации его температурных деформаций.The purpose of the invention is to increase the operational reliability of the pipeline by providing compensation for its temperature distortions.

Формула изобретенияClaim 1. Способ сооружения металлического горячего трубопровода, заключающийся в монтаже на берме и укладке на дно траншеи упругим изгибанием трубных плетей с образованием расчетных зазоров между их концами, засыпке плетей с защемлением в грунте, растягивании концов плетей для выбора зазоров нагреванием этих концов, их сварке и засыпке сваренных концевых стыков, отличающийся тем, что, с целью повышения эксплуатационной надежности трубопровода путем обеспечения компенсации его температурной деформаиии, вызванной подачей горячего продукта, укладку и засыпку плетей ведут с их нагреванием на всю длину.1. The method of constructing a metal hot pipeline, which consists in mounting on a berm and laying on the bottom of the trench by elastic bending of pipe lashes with the formation of design gaps between their ends, backfilling of lashes with pinching in the ground, stretching of the ends of the lashes to select the gaps by heating these ends, their welding and filling of welded end joints, characterized in that, in order to increase the operational reliability of the pipeline by providing compensation for its temperature deformation caused by the supply of a hot product, frets and lashes are filling their heating over the entire length. 2. Способ поп.1,отличающ и й с я тем, что нагревание укладываемых и засыпаемых плетей осуществляют нагнетанием горячего воздуха в их полости.2. The method of pop. 1, characterized in that the heating of the laid and poured lashes is carried out by forcing hot air in their cavity.
