FIELD: energy-saving technologies; heat insulation of pipe lines. SUBSTANCE: proposed coat made from soft heat-insulating material embraces outer surface of pipe line; it is additionally provided with insert laid in area of upper generatrix of pipe over entire length of this pipe and made heat-insulating material in form of cord, preferably from asbestos whose density is at least doubled density of soft heat-insulating material; its height is equal to 0.02-0.05 of outer pipe line. EFFECT: reduced losses of heat due to compensation of compression of heat-insulating material. 1 dwg |
