FIELD: transport machine building.
SUBSTANCE: group of inventions relates to a device and a method of applying a flexible shell material on outer surface (14) of insulation layer (4) for a pipe section. Essence of invention consists in the fact that insulation layer in form of cylinder having cylindrical central hole (10) is provided on first and second supporting elements (7), forming gap (9) between first and second supporting elements, at least of which first element is movable towards second support element and from it between first position, in which two supporting elements are close to each other, almost thus closing the gap, and a second position, in which the supporting elements are at a distance from each other, thus forming gap, which is larger than gap in first position, at that, layer (2) of flexible shell material is placed between insulation layer and two supporting elements so that adhesive surface of layer of flexible material of shell is facing towards insulation layer, or in such a way that the adhesive layer of the insulation layer faces towards the layer of flexible material of the shell, wherein movement of the insulation layer and the supporting elements relative to each other is provided, to provide movement of insulation layer and at least part of layer of flexible material of shell through gap between first and second supporting element, at that, providing movement of two supporting elements towards each other after the insulation layer and the layer of flexible shell material with its outer diameter pass through the gap between the first and second supporting elements, and at that, finally, flexible material of shell by means of adhesive is connected to insulation layer during or after specified stages of process.
EFFECT: technical result is simplification of treatment by producing a pre-fabricated pipe section, preferably a large diameter, which can be easily processed and installed and which allows to avoid damage caused by impossibility of shell removal or theft.
