Abstract
The disclosed invention relates to the field of producing the polyethylene heat shrink sleeves, which are used for connecting the heat-moistureproof elements of heat networks with the heat insulation and shielding shell from polyethylene. For producing a polyethylene heat shrink sleeves inside a section of polyethylene pipe a mount is located, as which a sealed elastic balloon is used, and first compressed gas under pressure of 1-6 atmospheres is pumped into it, and then the section of pipe is heated to the softening temperature of polyethylene and, thus, by means of compressed gas, the internal dimension of the section of pipe is increased to the required value, to which corresponds the external dimension of elastic balloon, after which the section of polyethylene pipe is cooled, the compressed gas is let out and the finished sleeve is removed from the mount. Technical result - simplification of the method, shortening the time of production of the sleeves, simplification of the equipment, and organization of nonwaste production.
