Изобретение относитс к экс11:1уатации магистральных и разво 1Я1ци. систем напорных трубонронодов, в частности к :(а1ците и от коррозии и обрастаний.The invention relates to the exploitation of trunk and development operations. systems of pressure piperonronods, in particular to: (a1cite and against corrosion and fouling.
Целью изобретени вл етс повышение надежности наносимого покрыти путем введени в трубонронод oднoвpeмeнн(J несколь ких коаксиально разме1иенных одна в дру- 1()й оболочек.The aim of the invention is to increase the reliability of the applied coating by introducing one-time-to-date (J several coaxially spaced one in the other (1) shells) into the pipeline.
(л шность изобретени по сн етс чер- тежом.(The best of the invention is illustrated in FIG.
В трубопровод 1 устанавливают тичные оболочки-рукава 2, выполненные из полимерных пленок, которые размешают ко- аксиально одну в другой. KoHiUii каждо11 оболочки выворачивают наизнанку и крен т к стенке трубопровода. оболочками системой 3 закачивают порцию кле 4, например хСпрут 4У. Зате.м в нолость трубопровода перед 1ос:1едней но ходу покрыти обо- ломкой подают от источника 5 рабочий агент, под действием которого оболочки синхронно перемешаютс но трубопроводу. После 11().1имериза 1ии к. 1е на стенке трубопровода создаетс многослойное полимерное нокры- тие.Piping sleeves 2, made of polymer films, which coaxially mix one into the other, are installed in the pipeline 1. KoHiUii each shell turns inside out and rolls against the wall of the pipeline. shells system 3 pumped a portion of glue 4, for example xSrut 4U. Zatom.M in the pipe floor before 1 ° C: 1 day but the course of the coating with the breakage is supplied from the source 5 by the working agent, under the action of which the shells are simultaneously mixed in the pipeline. After 11 (). 1imerize 1i to. 1e, a multi-layer polymeric coating is created on the pipe wall.
Пример. Покрывают трубопровод 0 700 мм и длиной 1 км, который имеет сквозные свищи, образованные на не.м в процессе ксп.чуатации.Example. Cover the pipeline 0 700 mm and a length of 1 km, which has a through fistula formed on it in the process of xp.chuatatsii.
В трубопровод устанавливают оболочку- рукав, который выполнен из 4 кольцевых пленок, установ:1енных коаксиально. Кажда н.ченка выполнена из поливинилхлори- да П1ВХ). Толщина каждой пленки равна 0,5 мм.A sleeve is installed in the pipeline, which is made of 4 annular films, installed: 1 coaxial. Each n.chenka is made of polyvinyl chloride P1VH). The thickness of each film is 0.5 mm.
Рукав устанавливают в трубопровод. Концы каждой пленки выворачивают наизнанку и креп т на стенке трубопровода.The sleeve is installed in the pipeline. The ends of each film are turned inside out and attached to the wall of the pipeline.
После закреплени очередной пленки за ней в трубопровод закачивают клей в количестве 0.3 т. Перед первой пленкой в трубопровод также закачивают 300 кг кле (всего 1,2 т). Затем в трубопровод подают сжатый воздух под давлением 0,2 ЛАПа и перемешают рукав по трубопроводу со скоростью 1 м/с.After fixing the next film behind it, glue in the amount of 0.3 tons is pumped into the pipeline. Before the first film, 300 kg of glue (total 1.2 tons) are also pumped into the pipeline. Then compressed air is fed into the pipeline under a pressure of 0.2 LAPa and the sleeve is stirred through the pipeline at a speed of 1 m / s.
Iloc.ie того как рукав будет уложен на всей длипе покрываемого участка, в трубопроводе на 6 ч оставл ют избыточное давление сжатого воздуха 2--3 ати. В течение 6 ч происходит поли.меризаци кле «Спрут-4У пленки склеиваютс между собой, образу жес1 кую конструкцию.Iloc.ie the fact that the sleeve will be laid on the entire length of the covered area, in the pipeline for 6 h leave an excess pressure of compressed air of 2--3 MPa. Within 6 hours, polymerizations of the Sprut-4U adhesive film are glued together to form a construction.
