Standard Gas Description
Standard gas is an industrial gas term, and a standard substance is a measuring standard substance with uniform concentration, good stability, and accurate measurement value. It plays a basic role in reproducing, preserving, and transmitting measurement values. Used in the fields of physics, chemistry, biology, and engineering measurement to verify measuring instruments and processes, evaluate the accuracy of measurement methods and the detection capabilities of testing laboratories, determine material and product characteristic values, and conduct value arbitration. Standard gases are divided into binary, ternary, and multivariate standard gases.
Product application
Ethylene standard gas is mainly used for the calibration and testing of petrochemical process control instruments, quality control of petrochemical products, environmental pollutant detection, automobile exhaust emission detection, various factory exhaust gas detection, calibration of mine alarms, calibration of medical instruments, quality testing of transformer oil in power systems, quality control of air separation products, calibration of traffic safety testing instruments, geological exploration and seismic monitoring, metallurgical analysis Gas appliance experiments and calorific value analysis, calibration of chemical fertilizer industry instruments, etc.
matters needing attention
Steel cylinder gas products are high-pressure filling gases, and can only be used after being depressurized and depressurized. The packaged gas cylinders have a service life, and any expired gas cylinders must be sent to relevant departments for safety inspection before they can continue to be used. When using exhaust gas in each bottle, the residual pressure inside the bottle should be kept at 0.5Mpa, with a minimum of 0.25MPa. The bottle valve should be closed to ensure gas quality and safe use. Bottled gas products should be classified and stacked during transportation, storage, and use. Combustible gases and combustion supporting gases are strictly prohibited from being placed together. They should not be near open flames or heat sources. They should be kept away from flames, oil and wax, explosive sunlight, heavy throwing, or impact. Arc ignition or electric arc on the cylinder body is strictly prohibited, and rough loading and unloading is strictly prohibited.
