Methane cylinder

Product description
First, the product name
Chinese name: methane cylinder
English name: CH4 cylinder
Second, product introduction
(1) Methane bottles are high-pressure vessels for storing and transporting nitrogen. They are generally hot-blasted and pressed from alloy structural steel and have 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 brown, and the word “methane” is written in white.
(3) The standard for gas storage capacity of methane bottles is pressure resistance.
(4) Methane is the simplest organic matter, and is the main component of natural gas, biogas, and gas. It is commonly known as gas. It is also the hydrocarbon with the smallest carbon content (the largest hydrogen content), and is also the main component of natural gas, biogas, oil field gas and coal mine pit gas. It can be used as a fuel and as a raw material for the production of hydrogen, carbon black, carbon monoxide, acetylene, hydrocyanic acid and formaldehyde.
(5) Methane is mainly used as a fuel, such as natural gas and coal gas, and is widely used in civil and industrial applications. As a chemical raw material, it can be used to produce acetylene, hydrogen, synthetic ammonia, carbon black, nitrochloromethane, carbon disulfide, methyl chloride, dichloromethane, chloroform, carbon tetrachloride and hydrocyanic acid.
Third, common uses
(1) Methane is a very important fuel and is the main component of natural gas, accounting for about 87%. Methane is colorless and odorless in a standard pressure room temperature environment; the special taste of domestic natural gas is an artificial odor added for safety, usually using methyl mercaptan or ethanethiol.
(2) Carbon black can be obtained by pyrolysis of methane, used as an additive for pigments, inks, paints and rubber; chloroform and CCl4 are important solvents. Methane is widely distributed in nature and is one of the main components of natural gas, biogas and pit gas. It can be used as a fuel and as a raw material for the production of hydrogen, carbon monoxide, carbon black, acetylene, hydrocyanic acid and formaldehyde. Methane is used as a standard fuel for heat value testing of water heaters and gas stoves.
(3) Production of standard gas for flammable gas alarms, calibration gas. It can also be used as a carbon source for solar cells, vapor phase chemical deposition of amorphous silicon films. And methane is used as a raw material for the production of pharmaceutical and chemical synthesis.
(4) In addition to fuel, it is widely used in the synthesis of ammonia, urea and carbon black, and can also be used to produce methanol, hydrogen, acetylene, ethylene, formaldehyde, carbon disulfide, nitromethane, hydrocyanic acid and 1,4-butanediol. . Chlorination of methane yields mono-, di-, trichloromethane and carbon tetrachloride.

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 methane 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.
