Abstract

Способ герметизации стыка предварительно изолированных труб предназначен для использования в строительстве или реконструкции трубопроводного транспорта для обеспечения гидравлической и механической защиты изоляции в неразъемных стыковых соединениях систем трубопроводов, например в теплогидроизолированных. Способ включает размещение термоусаживаемой муфты, выполненной из сшитой светопроницаемой пластмассы, поверх одной из труб-оболочек стыкуемых предварительно изолированных труб, причем используют термоусаживаемую муфту с предварительно нанесенным на ее внутреннюю поверхность адгезионным материалом, имеющим цвет, отличный от цвета трубы-оболочки. После сварки стыкуемых внутренних рабочих труб перемещают муфту на вторую трубу-оболочку и нагревают ее, обеспечивая термоусадку и образование клеевого соединения "муфта - трубы-оболочки", а после окончания термоусадки и образования соединения "муфта - трубы-оболочки" полость между торцами слоев изоляции, рабочими трубами и муфтой заполняют вспенивающейся композицией, при этом ведут визуальный контроль за образованием неразъемного соединения муфты с трубами-оболочками через муфту из светопроницаемой сшитой пластмассы. Технический результат заключается в сохранении свойств и характеристик изоляции в местах стыковых соединений в течение длительного периода времени и увеличении срока эксплуатации стыка и соответственно трубопроводных систем с таким стыком.The method of sealing the joint of pre-insulated pipes is intended for use in the construction or reconstruction of pipeline transport to provide hydraulic and mechanical protection of insulation in one-piece butt joints of pipeline systems, for example, in heat-hydro-insulated. The method includes placing a heat-shrinkable sleeve made of a cross-linked transparent plastic over one of the casing pipes of joined pre-insulated pipes, and using a heat-shrinkable sleeve with an adhesive material pre-printed on its inner surface that is different from the color of the casing pipe. After welding, the joined inner working pipes move the coupling to the second casing pipe and heat it, providing heat shrinkage and the formation of a glue "sleeve-shell-pipe" adhesive connection, and after the end of the heat-setting and formation of a sleeve-shell connection , the working pipes and the coupling are filled with a foaming composition, while visual control is carried out for the formation of a permanent connection of the coupling with the sheathed pipes through a coupling of translucent cross-linked plastic. The technical result is to preserve the properties and characteristics of the insulation in the joints for a long period of time and increase the lifetime of the joint and, accordingly, pipeline systems with such a joint.
