1. Способ нанесения изоляционного покрытия на трубопровод, отличающийся тем, что осуществляют последовательно намотку по винтовой линии изоляционной ленты со сменного рулона, причем в качестве изоляционной ленты используют ленту с адгезивом, разогрев участка ленты со стороны адгезива, разворот ленты адгезивом в сторону поверхности трубопровода и в момент контакта слоя адгезива с поверхностью трубопровода воздействуют на основу ленты рассредоточенной нагрузкой, причем ленту, направленную слоем адгезива от трубопровода, пропускают с внешней относительно трубопровода стороны, по меньшей мере, двух валков, размещенных на прямой вдоль нагревателя ленты, вокруг изолируемого трубопровода, причем в процессе намотки дополнительно измеряют температуру воздуха в зоне нагрева ленты или непосредственно за зоной нагрева со стороны адгезива.1. The method of applying an insulating coating to a pipeline, characterized in that the winding is carried out sequentially along the helical line of the insulating tape from a removable roll, moreover, an adhesive tape is used as an insulation tape, heating the portion of the tape from the side of the adhesive, spreading the tape with adhesive towards the surface of the pipe and at the moment of contact of the adhesive layer with the surface of the pipeline they act on the basis of the tape with a distributed load, and the tape directed by the adhesive layer from the pipeline is passed through eshney respect to the pipeline side, at least two rollers arranged on a straight line along the ribbon heater around the insulated pipeline, in which the winding process is further measured air temperature in the heating zone or the tape immediately behind the heating zone by the adhesive. 2. Способ по п. 1, отличающийся тем, что дополнительно корректируют температуру воздуха в зоне нагрева ленты.2. The method according to p. 1, characterized in that it further adjusts the air temperature in the heating zone of the tape. 3.

The method according to p. 1, characterized in that as an insulating tape use tape with a heat-shrinkable base. 4. Способ по п. 3, отличающийся тем, что намотанные по винтовой линии витки ленты равномерно нагревают.4. The method according to p. 3, characterized in that the windings of the tape wound along the helix are uniformly heated. 5. Способ по п. 1, отличающийся тем, что на поверхность трубопровода предварительно наносят слой праймера.5. The method according to p. 1, characterized in that the primer layer is previously applied to the surface of the pipeline. 6. Способ по п. 1, отличающийся тем, что участок ленты разогревают до температуры перехода адгезива в вязкотекучее состояние.6. The method according to p. 1, characterized in that the portion of the tape is heated to the temperature of the transition of the adhesive into a viscous flow state. 7. Способ по п. 1, отличающийся тем, что адгезив распределяют до заполнения им неровностей на поверхности трубопровода и вытеснения воздуха с одновременной фиксацией кромки ленты в месте нахлеста на предыдущий виток и приложением растягивающих усилий, возрастающих от кромки в месте нахлеста до противоположной кромки.7. The method according to p. 1, characterized in that the adhesive is distributed until it is filled with irregularities on the surface of the pipeline and air is displaced while fixing the edge of the tape in the place of overlapping to the previous turn and applying tensile forces increasing from the edge in the place of overlapping to the opposite edge. 8. Способ по п. 1, отличающийся тем, что температуру измеряют бесконтактно.8. The method according to p. 1, characterized in that the temperature is measured non-contact. 9. Способ по п. 1, отличающийся тем, что температуру измеряют дистанционно.9. The method according to p. 1, characterized in that the temperature is measured remotely.
