FIELD: engineering industry. ^ SUBSTANCE: invention refers to installation method of in-place curing tarred lining with internal impermeable layer. Installation method of in-place curing tarred lining on the available pipeline involves the following: a piece of lining is provided; lining is pulled in the pipeline; a receiving container having a free end for installation and receiving end with at least one fluid medium outlet; free end of the receiving container is put into the rear end of the lining; inlet fluid medium supply line is connected to the lining leading end; discharge line at fluid medium outlet is put in the receiving container; fluid medium is supplied to the lining in order to expand the lining to pipeline wall, and to pass through the lining to the discharge line for the purpose of tar curing in the lining; and lining is cooled. Invention also refers to pulling-in equipment that is put into the lining leading end, and lining is pulled-in to the access point. Before reaching the installation area the receiving container is attached to the lining end, and pulling-in is completed. Steam treatment is fully performed underground at minimum passage to underground access points. ^ EFFECT: providing air-pumping of pulled-in lining, and curing of tar with steam. ^ 17 cl, 13 dwg |
