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, нанесение адгезионного материала, имеющего другой цвет, отличный от цвета трубы-оболочки, на наружную поверхность обеих труб-оболочек. После сварки стыкуемых внутренних рабочих труб перемещают муфту на вторую трубу-оболочку и нагревают ее, обеспечивая термоусадку и образование клеевого соединения, 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. Изобретение позволяет сохранить свойства и характеристики изоляции в местах стыковых соединений в течение длительного периода времени, а также увеличить срок эксплуатации стыка.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 crosslinked translucent plastic on top of one of the casing pipes of joined pre-insulated pipes, applying an adhesive material having a different color than the casing pipe on the outer surface of both casing pipes. After welding, the joined inner working pipes move the sleeve to the second shell pipe and heat it, providing heat shrinkage and glue bonding, and after the heat shrinking and formation of the sleeve coupling, the shell between the ends of the insulation layers, the working tubes and the coupling is filled composition, while conducting visual monitoring of the formation of the permanent connection of the coupling with the pipe-shells through the coupling of translucent cross-linked plastic. The invention allows to maintain the properties and characteristics of the insulation in places of butt joints for a long period of time, as well as to increase the lifetime of the joint.
