FIELD: erection of pipe lines. SUBSTANCE: tubular surface is dried and coated with primer, after which hot mastic is poured on it in two stages and surface is coated helically with reinforcing packing material. mastic consists of bitumen-rubber or bitumen-polymer composition on base of bitumen at water saturation coefficient exceeding 0.1 percent. Two-layer cellular glass fabric is used as reinforcing material. Diameter of fibres of this material is equal to (0.25-0.35)T forming mesh whose insulation; prior to applying glass fabric tape on surface, it is drawn in wasting melt at temperature of 160 to 180 C. EFFECT: enhanced reliability.

Использование - строительство трубопровода. Сущность изобретения: сушат и грунтуют трубную поверхность, подают на нее двухкратным поливом горячую мастику и винтовым образом обертывают поверхность армирующим и оберточным материалами. В качестве мастики используют битумно-резиновый или битумно-полимерный состав, выполненный на основе битума с коэффициентом водонасыщения, не превосходящим 0,1%, а в качестве армирующего материала используют двухслойную ячеистую стеклоткань из волокон диаметром (0,25-0,35)Т, образующих в ленте ячейку шириной (0,25-0,5)Т, где Т - нормативная толщина слоя нормальной изоляции, при этом ленту стеклоткани перед нанесением на поверхность протаскивают в расплаве мастики при 160 - 180oС.Usage - pipeline construction. The essence of the invention: dried and primed the pipe surface, served on it by double watering hot mastic and screw-wrap the surface with reinforcing and wrapping materials. As a mastic, a bitumen-rubber or bitumen-polymer composition is used, made on the basis of bitumen with a water saturation coefficient not exceeding 0.1%, and as a reinforcing material, a two-layer cellular glass fabric of fibers with a diameter of (0.25-0.35) T is used forming a cell in the tape width (0.25-0.5) T, where T is the standard thickness of the normal insulation layer, while the fiberglass tape is pulled in the melt of the mastic at 160 - 180 o C. before being applied to the surface.
