Nitrogen cylinder

Product description
First, the product name
Chinese name: Nitrogen cylinder
English name: Nitrogen cylinder
Second, product introduction
(1) Nitrogen cylinder is a high-pressure vessel for storing and transporting nitrogen. It is generally made of alloy structural steel, which is hot-punched and pressed, and has 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 black, and the word “nitrogen” is written in yellow.
(3) The standard for the gas storage capacity of a nitrogen bottle is the pressure resistance.
(4) The upper limit of the pressure of a conventional nitrogen bottle is 15Mp (MPa), which is 147 atmospheres in terms of atmospheric pressure.
(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
2L; 4L; 8L; 10L These are relatively small in the laboratory, and 40L is used in factories that need these gases.
As for the industry that uses gas, there are too many. Such as light bulb manufacturing, food industry, hospitals, metal welding and so on.
Also, nitrogen bottles such as 4L and 8L are generally used on "breaking hammers", and nitrogen must be used during startup and maintenance.

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) Health hazard: The nitrogen content in the air is too high, causing the partial pressure of oxygen inhaled to drop, causing hypoxia and asphyxia. When the concentration of inhaled nitrogen is not too high, the patient initially feels chest tightness, shortness of breath, weakness and weakness; then there is irritability, extreme excitement, running, screaming, screaming, gait instability, called “nitrogen strontium”, which can enter drowsiness. Or coma. When inhaled at a high concentration, the patient can quickly stun and die due to breathing and heartbeat.
(2) When a diver dive deep, an anesthetic effect of nitrogen can occur; if it is transferred from a high pressure environment to a normal pressure environment, nitrogen bubbles will form in the body, compressing nerves, blood vessels or causing microvascular obstruction, and a "decompression sickness" occurs.
(3) Inhalation: (When the concentration is high) quickly leave the site to fresh air. Keep the airway open. If breathing is difficult, give oxygen. When the heartbeat stops, artificial respiration and chest compressions are performed immediately. Seek medical attention.
(4) Emergency treatment: quickly evacuate personnel from the contaminated area to the upper wind, and conduct isolation, strictly restricting access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear general working clothes. Cut off the source of the leak as much as possible. Proper ventilation and accelerated diffusion. The leaking container should be properly disposed of, repaired, and used after inspection.
(5) Handling precautions: Closed operation. Closed operation provides good natural ventilation. Operators must be specially trained to strictly follow the operating procedures. Prevent gas from leaking into the workplace air. Lightly load and unload during handling to prevent damage to cylinders and accessories. Equipped with leakage emergency treatment equipment.
(6) Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature of the reservoir should not exceed 30 °C. The storage area should be equipped with leakage emergency treatment equipment.
Note: The above specifications of the cylinder are general reference materials. If you have special requirements, please call 40009 63336, 18563963366.
