Abstract: A method of producing a high-pressure steel cylinder by forming from an individual dimension piece, consisting of an upper neck on the rounded end, which protrudes from the cylinder and it is provided by an opening the cylinder is additionally provided on its bottom with another bottom neck made in an inner material strengthening which is orientated insidewards of the high-pressure steel cylinder and the inner material strengthening is provided by a through-out opening.

Abstract: Blank of corrosion-resistant steel is coated with coating of water glass with thickness of 20 to 150 ?m, cured at 15 to 60° C., and heated in an induction furnace to the temperature of 1180° C. to 1260° C. The heated up blank is without cooling by water descaling transferred into an extrusion press and extruded here, while the coating is broken to pieces and largely removed. Drawing in a horizontal drawing press and necking are performed. After forming to the final shape of the cylinder, leftovers of coating are removed by pressure blasting. A corrosion-resistant thin-walled seamless high-pressure cylinder with volume of 5 to 260 litres is manufactured.
