Изобретение относитс  к области техники защиты от воздействи  зар дов статического электричества и может быть использовано в газовой, химической и других отрасл х иромышлениости . Известно, что при движении жидкостей или запыленных газов в трубопроводах возможна их электризаци  IJ. Возникноведие избыточных зар дов приводит к нежелательным последстви м , например к возможности поражени  обслуживающего персонала разр дом .статического электричества, возможноеги возникиовеии  пожарэ, взрыва. Поэтому магниты, по которым осуществл етс  перекачка газов и жидкостей, в частности трубопроводы, должны быть снабжены устройствами дл  отвода избыточных зар дов или их иейтрализации. Наиболее близкой к предложенной  вл етс  пластмассова  труба t наружным и внутренним электропроводными покрыти ми из композиции провод щих частиц и термореактивной смолы, причем покрыти  соединены между собой неремычкрй . расположенной на торце трубы The invention relates to the field of protection technology against the effects of static electricity charges and can be used in gas, chemical and other fields. It is known that when moving liquids or dusty gases in pipelines it is possible to electrify them IJ. The emergence of excess charges leads to undesirable consequences, for example, the possibility of damage to the operating personnel by the discharge of static electricity, possibly the occurrence of a fire or explosion. Therefore, the magnets through which gases and liquids are pumped, in particular pipelines, must be provided with devices for removing excess charges or neutralizing them. Closest to the proposed is a plastic tube t with external and internal electrically conductive coatings of a composition of conductive particles and a thermosetting resin, the coatings being interconnected with each other. located at the end of the pipe 2. . Недостатком ее  вл етс  сохранение высокой опасности взрыва из-за накоплени  внутри нее достаточно высокой разности потенциалов между различными участками трубы в силу нарушени  целостности покрыти  нэ торцовых част х трубы. Цельк) изобретени   вл етс  снижение опасности взрыва. Эта цель достигаетс  тем, что она снабжена по крайней мере одной дополнительной перемычкой , соедин ющей покрытие на внутренией поверхности с покрытием на наружной поверхности трубы и расположенной между торцом трубы и концом внутреннего п жрыти . Кроме тсгс, указанные перемычки выполнены нз того же материала что и материал покрыти , и дополнительна  перемычка соединена с перемычкой , расположенной на торце трубы. На чертеже представлена конструктивна  схема устройства. На торцовой части трубы I, изготовленной из пластмассы, электропроводное покрытие 2 имеетс  как на наружной поверхности, так и на внутренней. Труба выполнена с отверсти ми 3, которые также заполнены элементами 4 из того же материала, что и материал покрыти . В частном случае отверсти  могут представл ть собой продольные прорези, начинающиес  от торца трубы и заполненные хот -бы частично провод щими элементами по всей длине прорези. Торец второй трубы 5 выполнен аналогичным образом. Соединение труб, герметизируетс  уплотнением 6. Покрытие заземл етс  и представл ет собой термореактнвную смолу, в которую введены провод щие частицы. Предпочтительно использование угольных частиц. При движеаии, например, запыленного газа в TpyiSe происходит электризаци  ее, и на ней накапливаютс  избыточные зар ды статического электричества. Образование их иа торцовых участках устран етс  благодар  тому, что избыточные зар ды аекают по электропроводному покрытию. При нарушении целостности покрыти  на торце трубы провод щие элементы 4 осуществл ют надежный отвод зар дов, что снижает опасность взрыва. . Формула изобретени  1. Пластмассова  труба с наружным и внутренним электропроводными покрыти ми из композиции провод щих частиц и термореактивной2.. Its disadvantage is the preservation of a high risk of explosion due to the accumulation inside it of a sufficiently high potential difference between different sections of the pipe due to the violation of the integrity of the coating on the end portions of the pipe. The purpose of the invention is to reduce the risk of an explosion. This goal is achieved in that it is provided with at least one additional jumper connecting the coating on the inner surface with the coating on the outer surface of the pipe and located between the end of the pipe and the end of the inner cover. In addition to the tsgs, these jumpers are made of the same material as the coating material, and an additional jumper is connected to the jumper located at the end of the pipe. The drawing shows the structural diagram of the device. On the end of pipe I, made of plastic, the electrically conductive coating 2 is present both on the outer surface and on the inner surface. The pipe is made with holes 3, which are also filled with elements 4 of the same material as the coating material. In the particular case, the holes may be longitudinal slots starting from the pipe end and filled with hot-wire partially conductive elements along the entire length of the slot. The end of the second pipe 5 is made in the same way. The pipe joint is sealed by a seal 6. The coating is grounded and is a thermosetting resin into which conductive particles are introduced. Preferably the use of coal particles. When moving, for example, a dusty gas in TpyiSe, it is electrified, and excessive charges of static electricity are accumulated on it. The formation of their end sections is eliminated due to the fact that excess charges flow through the electrically conductive coating. If the integrity of the coating at the end of the pipe is disturbed, the conductive elements 4 reliably remove charges, which reduces the risk of an explosion. . Claims 1. Plastic tube with external and internal conductive coatings of a composition of conductive particles and thermosetting / // / шжттм смолы, соединенными между собой перемычкой , расположенной на торце трубы, отлинаюи .а с  тем, что,.с целью снижени  взрывоопасностн , она снабжена по крайней мере одной дополнительной перемычкой, соедин ющей внутреннее и наружное покрыти  между собой и расположенной между торцом трубы и концом внутреннего покрыти . 2. Пластмассова  труба по п. I, отличающа с  тем, что перемычки выполнены из материала покрыти . The resin, interconnected by a jumper located at the end of the pipe, is tilted so that, in order to reduce explosiveness, it is equipped with at least one additional jumper connecting the inner and outer cover between them and between the end of the pipe and the end of the inner cover. 2. A plastic pipe according to claim I, characterized in that the jumpers are made of a coating material. 3. Пластмассова  труба цо пп. I   2, отличаюи 1 с  тем, что дополнительна  перемычка соединена с перемычкой, расположенной на торце трубы. Источники информации, прин тые во внимание при экспертизе: 1. Макисмов Б. К. и др.
