Standard gas cylinder

Product description

First, the product name

Chinese name: standard gas cylinder, standard gas aluminum cylinder

English name: Standard gas cylinder

Second, product introduction

(1) The standard gas bottle is a high-pressure container for storing and transporting the standard gas. The general use rate or the alloy structural steel is hot-punched and pressed, and is cylindrical.

(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 words “standard gas” are written in white.

(3) The standard for the gas storage capacity of standard gas bottles is the pressure resistance.

(4) Standard gas is a gas industry term. Standard materials are uniform concentrations, well-stabilized and accurate measurement standards. They have the fundamental role of reproducibility, preservation and transfer of values. They are used to calibrate measuring instruments and measurement processes in the fields of physics, chemistry, biology and engineering measurement. To evaluate the accuracy of the measurement method and the detection capability of the testing laboratory, determine the characteristic value of the material or product, and perform quantitative arbitration.

Third, common uses

(1) Standard gas according to its use includes: standard gas for gas alarm, standard gas for electric energy, standard gas for petrochemical industry, standard gas for environmental monitoring, standard gas for medical and health, standard gas for instrumentation, etc.

(2) Standard gas can also be used for environmental monitoring, toxic organic matter measurement, vehicle emission gas test, natural gas BTU measurement, liquefied petroleum gas calibration standard, supercritical fluid process, etc.

(3) Large-scale ethylene plants, ammonia plants and other petrochemical enterprises require dozens of pure gas and hundreds of multi-component standard gas mixtures during installation, parking and normal production processes for calibration and calibration. Online analytical instruments used and instruments for analyzing raw materials and product quality.

(4) In addition to fuel, it is widely used in the synthesis of ammonia, urea and carbon black. It can also be used to produce methanol, hydrogen, acetylene, ethylene, formaldehyde, carbon disulfide, nitro standard gas, hydrocyanic acid and 1,4-butanediol. Wait. Standard gas chlorination can obtain mono-, di-, tri-chloride standard gases 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 cylinders or standard gas 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.
