FIELD: gas industry.
SUBSTANCE: invention relates to gas industry, particularly, to production of high-pressure metal-plastic bottles. Method of producing a high-pressure metal plastic bottle involves making an inner metal shell and an external power plastic shell. Strengthening of material of inner metal shell includes plastic deformation of metal material of inner shell by loading of metal-plastic bottle with preset internal pressure. Plastic deformation of metal material of the inner shell is performed after cooling of the inner metal shell to the specified negative temperature by filling of the metal-plastic HP bottle with the cryogenic liquid.
EFFECT: technical result consists in hardening material of inner shell of metal-plastic bottle.
