Verfahren zur Herstellung eines Hohlkörpers für hohen Innen- oder Außendruck


The invention concerns a method of producing a hollow body (1) having at least one opening (3) for high internal or external pressure. According to the invention, a preform (6) of metal or in particular of plastics is expanded by a high internal pressure to form an inner container (4) and externally, under high internal pressure, is optionally sheathed, extrusion-coated, dipped or lapped. The internal pressure is so high that during sheathing, extrusion-coating, dipping or lapping the inner container (4) is not deformed at all or only slightly.
