Definitions
- the invention relates to a use of a known compressed gas container made of a rustproof chrome-nickel-stainless steel alloy.
- the invention is based on the object, a diver bottle provide high mechanical strength, Corrosion resistance and reliability distinguished.
- the task is accomplished by the use of a pressurized gas container Made of a stainless chromium-nickel-stainless steel alloy Diver bottle solved.
- This method therefore allows the production of a diver bottle with a compressed gas tank made of stainless steel, which is characterized by high mechanical strength with low wall thickness and at the same time a correspondingly low weight.
- a procedure for Production of compressed gas containers made of stainless steels "Kryoverformung" is described in DE-A 36 14 290.
- Compressed gas tank with particularly high mechanical strength are obtained when the compressed gas tank is made of a stainless steel consisting of a metastable austenitic CrNi steel alloy with a titanium and niobium content of max. 0.02 wt .-%, one Nickel content between 9 and 11 wt .-% and a carbon content between 0.03 and 0.045 wt .-%. Except for minor Modifications are, for example, among the Material numbers 1.4301, 1.4306 and 1.4404 (DIN 17440) known, Austenitic stainless steels suitable.
- the wall thickness of the pressurized gas container is in the range between 2 mm and 5 mm.
- the mechanical strength and the Weight-related storage capacity of such stainless steel containers corresponds approximately to that of pressure vessels from conventional ferritic Pressure vessel steels.
- a further improvement results from an electrolytic polishing the tank inner wall.
- the diver bottle is particularly suitable for use with a dipping gas, which has an oxygen content of at least 32% by volume having. Due to the high oxygen content, the formation of a the further corrosion preventing dense passivation layer facilitates the inner wall of the compressed gas container.
- a dipping gas which has an oxygen content of at least 32% by volume having. Due to the high oxygen content, the formation of a the further corrosion preventing dense passivation layer facilitates the inner wall of the compressed gas container.
- passivation layers forming steel alloys are again the alloys according to the material number 1. 4301, 1.4451 or 1. 4306 according to DIN 17440 called.
- the compressed gas container by plastic Kryoverformung a hollow cylindrical raw form of stainless steel molded.
- the compressed gas tank Due to the Kryoverformung the compressed gas tank receives the desired high strength.
- the hollow cylindrical Rohform by a certain amount at low temperatures, such as the Temperature of the liquid nitrogen, plastically deformed.
- the degree of Consolidation goes hand in hand with the proportion of the microstructure that is at the Deformation is converted into martensite. Since in martensite converted part of the structure with decreasing deformation temperature and increasing degree of deformation increases, the deformation temperature below the so-called martensite temperature, above which no martensitic transformation takes place. The best results are obtained when the deformation takes place below the so-called "Ms temperature". This is the Temperature at which the martensite transformation of the microstructure also without simultaneous deformation.
- the reference numeral 1 of the diving bottle is a total assigned.
- the diver bottle 1 consists of a pressurized gas container 2 for receiving an immersion gas 3 with an opening 4, in a valve 5 for filling and for removing the immersion gas. 3 pressure-tight is used.
- the pressurized gas container 2 consists of an austenitic stainless steel CrNi alloy, under the material number 1.4301 (according to DIN 17440) is commercially available and slightly modified in style is that, unlike the composition according to the DIN standard the titanium and niobium content at about 0.02 wt .-%, the Nickel content at 10 wt% and the carbon content at 0.04 wt% lie.
- the inner wall 6 of the compressed gas container 2 is electrolytic polished. Its filling volume is 10 l, its wall thickness 3.5 mm and his weight is about 12 kg.
- the compressed gas tank 2 is characterized a high bursting pressure of about 650 bar, resulting in a permissible operating pressure of 200 bar.
- the immersion gas 3 is an oxygen-rich Gas mixture with an oxygen content of between 32 and 60% by volume, which is commercially available under the name "Nitrox".
- the tube shape with an initial wall thickness of 4 mm immersed in a container of liquid nitrogen immersed in a container of liquid nitrogen.
- a Cryo high-pressure pump is liquid nitrogen in the raw form introduced and thus generates an internal pressure of about 700 bar, the Rohform on the final geometry of the compressed gas container 2 stretches.
- the austenitic stainless steel structure is solidified by martensite formation.
- the deformation process is completed.
- the Embodiment has been in the Kryoverformung the wall thickness of the pipe reduced by slightly more than 10%.
- the pressurized gas container becomes electrolytic polished.
- the compressed gas container 2 thus produced characterized by low weight, high mechanical strength and corrosion resistance, so that it is suitable for use as Diving bottle is particularly well suited.
