Изобретение относитс  к эксплуатации магистральных трубопроводов и может быть использовано при защите их от коррозии и обрастаний.The invention relates to the operation of trunk pipelines and can be used to protect them from corrosion and fouling.

Це.тью изобретени   вл етс  повышение надежности и долновечности покрыти  путем нанесени  на стенку трубопровода перфорированного пленочного рукава и покрыти  его сверху дополнительным пленочным рукавом с металлическим подслоем, который подсоедин ют к положительному полюсу источника посто нного тока, а стенку трубопровода подсоедин ют к его отрицательному полюсу.The invention is to increase the reliability and durability of the coating by applying a perforated film sleeve to the pipe wall and coating it on top with an additional film sleeve with a metal sublayer that is connected to the positive pole of the DC source and the pipe wall is connected to its negative pole .

На чертеже представлена схема ocyntecT- в. 1ени  предлагаемого способа.The drawing shows the scheme ocyntecT-in. 1 of the proposed method.

Стенку тр бопровода 1 покрывают пленочным 11ерфорированп1 1м рукавом 2 свер0The wall of the trunk pipeline 1 is covered with a film 1 is punched 1 m with a sleeve 2 wer0

ху него нанос т дополнительный пленочный рукав 3 с металлическим подслоем, например напыленным порошком цинка. Стенку трубопровода подсоедин ют к отрицательному полюсу источника посто нного тока 4, а металлический подслой к его положительному полюсу.An additional film sleeve 3 with a metallic underlayer, for example, sprayed zinc powder, is applied to it. The wall of the pipeline is connected to the negative pole of the DC source 4, and the metal sublayer to its positive pole.

При подаче тока до защитного электрохимического потенциала обеспечиваетс  ка- годна  (ашита. Пока рукав 3 не пару теп, катодна  защита не действует.When a current is applied to the protective electrochemical potential, it is provided that it is curable (ashta. While sleeve 3 is not a couple of tep, the cathode protection does not work.

Если в процессе эксплуатации будет нарушен защитный рукав 3, вода попадет в пространство между рукавами 2 и 3, а так как рукав 2 перфорирован, то ток начнет увеличиватьс  и, следовательно, начнет действовать катодна  зашита. Чем больше будет порывов рукава, тем больше будет подаватьс  ток.If during operation the protective sleeve 3 is broken, water will fall into the space between the sleeves 2 and 3, and since the sleeve 2 is perforated, the current will begin to increase and, therefore, the cathode protection will start. The greater the gust of the sleeve, the more current will be supplied.
