The manufacturer of gas purification equipment tells you about the application of high-purity helium!

Now the application of gas is more and more extensive. We can see his figure in industry and our daily life. The high-purity helium shall be used after being depressurized by pressure reducers such as YQY-12 or 152IN-125. Soap water shall be used to detect the leakage of the gas pipeline before use to ensure that the gas pipeline does not leak. Ensure that there is no leakage of helium and keep the workplace ventilated.

When the oxygen content is lower than 19.5% due to the increase of helium content, the patient first appears to have rapid breathing, inattention and ataxia; Then there are fatigue, weakness, irritability, nausea, vomiting, coma, convulsions, and death.

The packaged gas cylinders have a service life. All expired gas cylinders must be sent to the relevant department for safety inspection before they can continue to be used. When the tail gas is used in each cylinder of helium, the residual pressure in the cylinder shall be kept at 0.5MPa, which shall not be less than 0.25MPa. The cylinder valve shall be closed to ensure the gas quality and use safety.

On the other hand, there are strict operation procedures for the transportation and application of gas bottles. They shall be stacked by classification, and shall not be close to open fire and heat source. They shall be kept away from fire, oil wax, explosion, heavy throwing and impact. Arc striking or arc striking on the cylinder body is prohibited. Rough loading and unloading is prohibited. Short distance moving helium cylinders shall be transported by special cylinder trolleys, and long distance moving cylinders shall be transported by dangerous goods transport vehicles.
