The present invention describes a method of manufacturing high pressure tanks of low unit weight with reinforced corrugated metal sheath in which :. a corrugated tube is circumferentially armed,. a metallic reservoir is introduced inside the reinforced tube,. the assembly consisting of the reinforced tube and the tank, with the exception of the openings, is armed longitudinally. the material of the metal tank is made to flow by plastic deformation under the effect of internal pressure so as to obtain a corrugation of the cylindrical part of the metal tank. |
