Standardgasbeschreibung
Standard gas is an industrial gas term, and a standard substance is a standard substance with uniform concentration, good stability, and accurate measurement values. 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.
application area
Common standard gases according to their uses include: standard gases for the power industry, environmental monitoring, petrochemical, fire alarm, medical and health, and instrumentation.
Angelegenheiten, die Aufmerksamkeit erfordern
Bottled gas products are high-pressure filling gases, and they should be depressurized and depressurized before use. 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.
