Xenon cylinder

Product description
First, the product name
Chinese name: Xenon cylinder
English name: hydrogen cylinder
Second, product introduction
(1) Helium cylinders are high-pressure vessels for storing and transporting nitrogen. They are generally hot-pressed and pressed from alloy structural steel and have a cylindrical shape. Used in hospitals, first aid stations, nursing homes, food factories, chemical plants, etc.
(2) The shoulder of the cylinder is marked with the working pressure, test pressure, volume, weight, and other information. The surface is painted in gray, and the words “氦” are written in green.
(3) The standard for gas storage capacity of helium cylinders is pressure resistance.
(4) The upper limit of the pressure of a conventional helium cylinder is 15Mp (MPa). The atmospheric pressure is 147 atmospheres.
(5) The pressure resistance test value is 22.5Mp.
(6) The pressure inside a conventionally filled cylinder should be around 12~15Mp.
(7) The gas in the bottle cannot be completely used up, and the residual pressure of not less than 0.1-0.2MP should be retained.
Third, common uses
Helium is widely used in military, scientific research, petrochemical, refrigeration, medical, semiconductor, pipeline leak detection, superconducting experiments, metal manufacturing, deep sea diving, high-precision welding, optoelectronics production.
(1) Low-temperature cold source: The liquid helium can be used for ultra-low temperature cooling by using the low boiling point of liquid helium at -268.9 °C. Ultra-low temperature cooling technology has a wide range of applications in the field of superconducting technology. Superconducting materials need to exhibit superconducting properties at low temperatures. In most cases, only liquid helium can easily achieve such extremely low temperatures. Superconducting technology in the transportation industry, the magnetic levitation train, the medical field of MRI equipment have a larger application.
(2) Balloon inflation: Since the density of helium is much smaller than that of air (the density of air is 1.29kg/m3, the density of helium is 0.1786kg/m3), and the chemical properties are extremely inactive, safer than hydrogen (hydrogen can be in the air) Burning may cause an explosion. Helium is often used to fill gas in spacecraft or advertising balloons.
(3) Inspection and analysis: The superconducting magnet of the nuclear magnetic resonance analyzer commonly used in instrumental analysis needs to use liquid helium to cool down. In the gas chromatographic analysis, helium gas is often used as a carrier gas, and the helium gas permeability is good and non-flammable. Also used in vacuum leak detection, such as helium mass spectrometer leak detectors.
(4) Protective gas: With the inactive chemical properties of helium, helium is often used as a shielding gas for welding metals such as magnesium, zirconium, aluminum and titanium.
(5) Other aspects: Helium gas can be used as a high-vacuum device, and a nuclear reactor is used as a pressurized gas for transporting liquid propellants such as liquid hydrogen and liquid oxygen on rockets and spacecraft. Helium is also used as a cleaning agent for atomic reactors, a mixed gas for breathing in the field of marine development, a gas filled with a gas thermometer, and the like.

Fifth, the production process
1. Overall flushing type:
Billet sawing and cutting - induction heating - anti-extrusion punching - drawing - picking - closing - heat treatment - external sandblasting - mouth thread processing - internal sandblasting (or phosphating) treatment - hydraulic test - upper valve -Airtight test-spray-drying-inspection-inbound
2, steel pipe spinning forming method:
Steel pipe sawing and cutting - induction heating - spinning seal bottom - milling insole - induction heating - spinning pressure closing - heat treatment - sand blasting - mouth thread processing - internal sandblasting (or phosphating) treatment - hydraulic test - upper valve -Airtight test-spray-drying-inspection-inbound
Sixth, matters needing attention
(1) High-pressure gas cylinders must be kept in separate parts and kept in a stable position when standing upright; keep the gas cylinders away from heat sources to avoid exposure and strong vibration; generally, the volume of gas cylinders in the laboratory should not exceed two bottles.
a. At the shoulder of the cylinder, use the steel stamp to mark the manufacturer's date of manufacture. The cylinder model is working. The pressure and pressure test pressure and pressure test date and the next inspection date, gas volume, and cylinder weight.
b. In order to avoid confusion when using various cylinders, the cylinders are often painted in different colors to indicate the name of the gas in the bottle.
(2) The pressure reducer selected on the high pressure gas cylinder should be classified. The screw buckle should be tightened during installation to prevent leakage. When opening and closing the pressure reducer and the on/off valve, the action must be slow; when using, the switch valve should be rotated first. After opening the pressure reducer; when it is used up, first close the on-off valve, after exhausting the remaining gas, then turn off the pressure reducer. Do not just turn off the pressure reducer, do not close the switch valve.
(3) When using a high pressure gas cylinder, the operator should stand in a position perpendicular to the cylinder interface. Do not knock on the impact during operation, and always check for leaks. Pay attention to the pressure gauge reading.
(4) Oxygen cylinders or helium cylinders, etc., should be equipped with special tools and are strictly prohibited from contact with oil. Operators should not wear clothing gloves that are contaminated with various greases or that are sensitive to static electricity to avoid burning or explosion.
(5) The distance between the flammable gas and the combustion-supporting gas cylinder should be greater than ten meters from the open flame (if it is difficult to achieve, measures such as isolation can be taken).
(6) After use, the cylinder should be kept at a residual pressure of 0.05 MPa or more as specified. The flammable gas should be 0.2MPa~0.3MPa (about 2kg/cm2~3kg/cm2 gauge pressure). H2 should be kept 2MPa to prevent danger when re-inflating, and it can not be used up.
(7) Various cylinders must be regularly inspected for technical inspections. Gas cylinders filled with general gas shall be inspected once every three years; if severe corrosion or serious damage is found during use, inspection shall be carried out in advance.
Note: The above specifications of the cylinder are general reference materials. If you have special requirements, please call 40009 63336, 18563963366.
