FIELD: machine building.
SUBSTANCE: heat protective coat is formed at mandrels to connect metal flange therewith for vulcanisation. Lengthwise and crosswise segments of 0.2-0.3 mm diameter nitinol wire pre-trained identically to flange curvature are uniformly applied on heat insulating material surface in flange zone after application of second and two last layers. Then other layers are applied to cure the thus formed stack.
EFFECT: higher reliability.
