FIELD: construction industry.
SUBSTANCE: method involves overlapped winding of annular woven fabric layers on elastic mandrel in the form of straps with length not less than length of cover and width equal to perimetre of the latter; each annular layer is fixed with spiral winding of textile fibre, and after all layers are wound and fixed, woven fabric is stitched with zigzag seam of thread made from fibrous material, woven fabric is soaked with bonding agent, drying, installation in split die, heating of assembly and polymerisation, and after it is completed, assembly is cooled, cover with mandrel is removed from die and taken from mandrel.
EFFECT: enlarging manufacturing capabilities and improving reliability.
