Definitions

  • the present invention relates to a double-walled metallic compressed gas cylinder that is as light as possible, in particular for high-purity and aggressive special gases.
  • Such pressurized gas bottles are necessary in the context of the constantly increasing requirements for test and process gases, for example in microelectronics development and production, where the fabrication-technically achievable surface cleanliness of the single-walled aluminum pressurized gas bottles used so far is no longer sufficient, so that stainless steel bottles will be necessary in the future.
  • the single-walled stainless steel bottles are very expensive to manufacture and material, especially because they have to be made thicker-walled because of the lower material strength than steel bottles of the same strength and thus also significantly increase the transport weight.
  • a pressure vessel made of steel for storing gaseous hydrogen in which the inner surface of the pressure vessel is provided with a protective layer made of a special metal.
  • Metals of the first or second secondary group or the third main group of the periodic system are proposed as protective layers, in particular zinc, cadmium, silver, gold or lead.
  • Protective layers of this type should be impermeable to hydrogen. About the application of this protective layer is only said that it can be applied galvanically or mechanically to the inner surface of the pressure vessel.
  • German patent 31 03646.5 a pressure vessel for gases, in particular made of light metal, with a wound fiber-reinforced plastic jacket is proposed.
  • US Pat. No. 3,268,103 proposes a pressure vessel for gases, particularly at elevated temperatures and pressures.
  • the thick-walled and pressure-resistant outer container is welded together from several parts of different steel and then lined with insulation and a continuous thin-walled stainless steel layer on the inside.
  • the object of the present invention is a double-walled metallic compressed gas cylinder that is as light as possible, in particular for high-purity or special gases. These pressure bottles should neither contaminate the gases they contain nor react chemically with them.
  • the inner wall should therefore consist of stainless steel, while the outer wall should consist in one piece of a ferritic quenched and tempered steel because of its higher strength and easier processing.
  • a pressurized gas cylinder is proposed from a thick-walled pressure-resistant outer container, in particular from a high-strength ferritician ⁇ quenched and tempered steel, and an essentially thin-walled inner container made from corrosion-resistant stainless steel with a thick-walled neck to accommodate a thread for the fittings common on such pressure bottles.
  • the outer pressure-resistant sleeve surrounds the inner container and also its thick-walled neck or collar in a tight fit so that the forces acting on the fittings or on this thick-walled neck are passed on directly to the outer container.
  • the thin-walled inner container is first pushed into the outer container, which is open at one end, and only then is the outer container deformed or narrowed by flow pressure, ie with rotating rollers, as is customary in the production of single-walled pressure bottles.
  • the inner container is usually assembled from several parts beforehand, which can then be welded, cleaned and tested with ultrasound. It is useful to give the inner container a shape that corresponds to the later inner shape of the outer container.
  • the inner container can be expanded hydraulically or pneumatically-plastically so that it rests against the outer container without any gaps. Any gaps that may arise due to manufacturing inaccuracies are filled in using this method.
  • the inner container is expediently given some waves on purpose. With rotating waves it is achieved that the inner container rests against the bottom or neck of the outer container at both ends. With longitudinal waves in the cylindrical part of the inner container, its introduction into the outer container is facilitated. These waves are also brought to rest against the outer container by the subsequent expansion.
  • the thick-walled neck of the inner container has a likewise thick-walled collar, the outer shape of which corresponds to the inner shape of the outer container at the upper end.
  • This collar is used as a system during the deformation of the outer container, especially at the transition to its neck.
  • the thick-walled neck of the inner container has on the outside in the cylindrical part one or more annular grooves into which the neck of the pressure-resistant outer container is pressed in order to transmit any axial forces between the two and to seal the gap.
  • the gap between the inner container and the outer container is evacuated before the inner container is widened so that no significant amounts of gas or air can remain here.
  • a test bore is proposed in the outer container, which is closed after the test.
  • Figures 1 to 3 each show a vertical longitudinal section through a pressurized gas cylinder according to the invention, in each case in the right half before completion and in the left half after completion.
  • FIG. 1 shows the principle of the invention.
  • the thick-walled outer container 1 consists initially of a container that is open on one side, for example produced by the deep-drawing process, the wall thickness of which is calculated as a function of strength, gas pressure and bottle diameter.
  • the thin-walled inner container consists of a hemispherical base 2, a cylindrical jacket 3 and a transition piece 4 and has a thick-walled neck 5, with parts 2 to 5 being connected to one another by welds that can be properly checked before being installed in the outer container.
  • Part 5 also contains a circumferential annular groove 6 with rounded edges, into which the neck of the outer container 1 is pressed when it is later formed.
  • the upper end of the outer container 1 is deformed or narrowed by flow pressing, as is customary in the manufacture of single-walled pressure bottles. It makes sense here to give the inner container, which can be deformed much more easily beforehand, the shape from the outset that will change when the outer container 1 is later deformed results.
  • the outer container 1 can be welded to the neck 5 at 7. However, both containers are also connected to one another in a form-fitting manner. Parts 2 to 4 are drawn thicker than necessary to make them clearer. A wall thickness of 0.5-0.8 mm is sufficient and can be welded properly.
  • the outer container and also the neck of the inner container can have a wall thickness of 5 to 10 mm if the inner container has a diameter of 150 mm, for example.
  • FIG. 2 shows the upper part of a pressurized gas cylinder with a thick-walled outer container 11 and a thin-walled inner container 13, which is still welded to the thick-walled collar 14 of the neck 15 in the cylindrical part.
  • the neck 15 has some annular grooves 16 on the outside into which the neck of the outer container 11 is pressed.
  • the lid 18 of the réellebehalter 13/14 is closed only during the processing, so that it can be filled with inert gas and is protected against impurities'.
  • the outer container 11 contains a test bore 19 with which the gap between the outer container 11 and the inner container 13/14 can be evacuated and checked for leaks.
  • FIG. 2 shows the final state of the pressurized gas cylinder, the lid 18 being removed and the neck 15 being provided with an external thread for the usual connection fittings.
  • FIG. 3 shows a thick-walled outer container 21 externally corresponding to FIG.
  • This neck 25 is first made in one piece and closed and later turned to the final shape with a thread.
  • the forming technology for the outer container 21 is certainly a bit more complex in this case because the mecanicbeh lter 23 between its largest diameter and the neck 25 can not serve as an abutment for the deformation.
  • the outer container 21 As in FIG. 2, it contains a test bore 29, which in this case leads to a radial gap 30 in the neck 25. Before the deformation of the outer container 21, the neck 25 is initially produced longer than is necessary later so that it can be held better during the deformation.
  • a pressurized gas cylinder which is suitable for numerous high-purity gases in microship production, such as. B. hydrogen, oxygen or nitrogen is suitable.
  • the inner container for example made of stainless steel 1.4406, can be made completely smooth on the inside and without gaps and cleaned to such an extent that the purity of 99.999% required for microship production can be achieved. If the so-called annealing colors occurring during welding, i. H. If surface changes caused by the welding heat are to be avoided, a steel should be selected that contains neither niobium nor titanium.
  • the present pressurized gas cylinder is suitable for aggressive special gases, such as. B. chlorine, ammonia or sulfur hexafluoride.
