Abstract
1. Способ нанесения изоляционной манжеты на стык трубопровода, отличающийся тем, что проводят подготовку поверхности изолируемого стыка, наносят на подготовленную поверхность рулонный адгезивный материал, нагревают его до размягчения, на размягченный слой адгезивного материала помещают отрезок термоусаживающейся полимерной ленты, соединяют внахлест концы термоусаживающейся полимерной ленты с формированием манжеты, на место соединения концов устанавливают замковую пластину и проводят термоусаживание манжеты. ! 2. Способ по п.1, отличающийся тем, что при подготовке поверхности изолируемого стыка разогревают его для удаления конденсата. ! 3. Способ по п.1, отличающийся тем, что при подготовке поверхности изолируемого стыка удаляют с поверхности загрязнения и неровности. ! 4. Способ по п.3, отличающийся тем, что при подготовке поверхности изолируемого стыка дополнительно после удаления с поверхности загрязнений и неровностей нагревают поверхность изолируемого стыка для удаления конденсата. ! 5. Способ по п.3, отличающийся тем, что при подготовке поверхности изолируемого стыка после удаления с поверхности стыка загрязнений и неровностей наносят слой праймера. ! 6. Способ по п.1, отличающийся тем, что нанесенный слой нанесенного рулонного адгезивного материала разогревают до температуры перехода в вязкотекучее состояние. ! 7. Способ по п.1, отличающийся тем, что используют термоусаживающуюся полимерную ленту, обращенная в сторону поверхности стыка поверхность которой дополнительно содержит слой адгезива толщиной до 300 мкм. ! 8. Способ по п.7, отличающийся тем, что указанный слой адгезива дополнительно подогрева� 1. A method of applying an insulating cuff to a pipe joint, characterized in that the surface of the insulated joint is prepared, a roll of adhesive material is applied to the prepared surface, heated to soften, a piece of heat-shrinkable polymer tape is placed on the softened layer of adhesive material, and the ends of the heat-shrinkable polymer tape are lapped with the formation of the cuff, at the junction of the ends set the locking plate and conduct heat-shrink cuff. ! 2. The method according to claim 1, characterized in that when preparing the surface of the insulated joint, it is heated to remove condensate. ! 3. The method according to claim 1, characterized in that when preparing the surface of the insulated joint, contaminants and roughnesses are removed from the surface. ! 4. The method according to claim 3, characterized in that when preparing the surface of the insulated joint, additionally after removing contaminants and irregularities from the surface, the surface of the insulated joint is heated to remove condensate. ! 5. The method according to claim 3, characterized in that when preparing the surface of the insulated joint after removing contaminants and irregularities from the joint surface, a primer layer is applied. ! 6. The method according to claim 1, characterized in that the deposited layer of the applied roll adhesive material is heated to the temperature of transition to a viscous flow state. ! 7. The method according to claim 1, characterized in that a heat-shrinkable polymer tape is used, the surface of which faces the interface, additionally contains an adhesive layer up to 300 microns thick. ! 8. The method according to claim 7, characterized in that said adhesive layer is further heated�
