Acetylene cylinder

Product description
First, the product name
Chinese name: acetylene cylinder
English name: Acetylene cylinder
Second, product introduction
(1) Acetylene bottle is a high-pressure container for storing and transporting acetylene. It is generally made of alloy structural steel, which is hot-punched and pressed, and has a cylindrical shape.
(2) The shoulder of the cylinder is marked with the working pressure, test pressure, volume, weight, and other information. The surface is painted white, and the word "acetylene" is written in red.
(3) The standard of gas storage capacity of acetylene bottles is the pressure resistance.
(4) An acetylene bottle is a container for storing and transporting acetylene. The shape is similar to an oxygen cylinder, but its construction is more complicated than an oxygen cylinder. The main part of the acetylene bottle is a cylindrical welded bottle body rolled from high quality carbon steel or low alloy steel.
(5) The bottle is filled with a porous filler filled with acetone to enable stable and safe storage of acetylene in the bottle. When used, the acetylene dissolved in acetone is decomposed and flows out through the acetylene bottle valve. The acetone remained in the bottle to dissolve and press acetylene again. Asbestos is placed in the long hole in the center of the packing under the acetylene bottle valve to help the acetylene decompose from the porous packing.
Third, common uses
(1) Acetylene can be used to illuminate, weld, and cut metal (oxygen flame), and is also a basic raw material for producing acetaldehyde, acetic acid, benzene, synthetic rubber, synthetic fibers, and the like.
(2) When acetylene is burned, it can generate high temperature. The temperature of oxyacetylene flame can reach about 3200 °C, which is used for cutting and welding metal. Supplying an appropriate amount of air, it can be completely burned to emit bright white light, and can be used as an illumination source where the electric lamp is not popular or has no power. Acetylene is chemically active and can react with many reagents.
(3) Before the 1960s, acetylene was the most important raw material for organic synthesis and is still one of the important raw materials. If it is added with hydrogen chloride, hydrocyanic acid or acetic acid, a raw material for producing a high polymer can be produced.
(4) Under different conditions, acetylene can undergo different polymerizations to form vinyl acetylene or divinyl acetylene. The former can be added with hydrogen chloride to obtain the raw material of chloroprene rubber. 2-chloro-1,3-butyl Alkene. At the high temperature of 400-500 ° C, acetylene can undergo cyclic tri-polymerization to form benzene. With nickel cyanide Ni(CN) 2 as catalyst, cyclooctatetraene can be formed at 50 ° C and 1.2-2 MPa.
(5) Acetylene is decomposed into carbon and hydrogen at a high temperature, whereby acetylene black can be produced. Under certain conditions, acetylene is polymerized to form aromatic hydrocarbons such as benzene, toluene, xylene, naphthalene, anthracene, styrene, and anthracene. A series of extremely valuable products can be produced by substitution reactions and addition reactions.

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 bottles or acetylene bottles, 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.
