FIELD: transportation of different products through tubes, namely technique for making insulation tapes designed for protecting main oil pipelines, oil product pipelines, gas ducts, sewage tubes and so on against soil corrosion. SUBSTANCE: installation includes unit for applying insulation mastic having system for stabilizing temperature of insulation mastic directly before feeding it to application zone on flexible tape. Said system includes at least one reservoir with pipelines for feeding insulation mastic and apparatus for adjusting thickness of layer of applied insulation mastic along width of flexible tape. Said apparatus has two cone surfaces adjusted relative to flexible tape and arranged along edges of flexible tape. EFFECT: enhanced efficiency of installation due to improved operational efficiency of unit for applying insulation mastic, enhanced quality of insulation tape due to eliminating penetration of insulation mastic onto back side of flexible tape. 4 dwg
