Precautions and issues related to purchasing high-purity helium gas

Helium, high-purity helium

High purity helium gas is a special gas widely distributed in nature. To extract high-purity helium gas, high equipment and technology are required. Different purities of high-purity helium gas also have different methods. To buy high-purity helium gas, find Wuhan Yisi Tuopu Technology Co., Ltd. Click on the online inquiry or call our hotline:+86 189 8614 9031.

Wuhan Yisi Tuopu Technology Co., Ltd. will take you to understand some precautions when purchasing high-purity helium gas, so that you can choose some high-purity helium gas that suits you when purchasing high-purity helium gas, so as not to waste it.

Customers who fill high-purity helium balloons, compared to other industries, do not need high-purity helium gas and can choose high-purity helium gas.

2. Used together with high-purity carbon dioxide and high-purity nitrogen as laser gas for carbon dioxide laser cutting machines, this also belongs to high-purity gas and does not require high-purity helium gas.

3. Liquid helium is used as a superconducting magnet for nuclear magnetic resonance imaging instruments. It is a medical high-purity helium gas with certain purity requirements. Use it according to the instructions of the instrument and do not seek cheapness or damage the instrument and equipment.

4. Respiratory gas used in deep-sea operations together with medical oxygen, which belongs to medical gas. It is recommended to use high-purity and high-purity helium gas to avoid affecting its use.

5. Used as a leak detection gas for helium leak detectors in the air conditioning field, high-purity gas is required for leak detection.

6. Used as a protective gas for special welding together with high-purity argon gas, the requirements for high-purity gas are not high.

7. Used as a carrier gas for gas chromatography/gas chromatography-mass spectrometry and other instruments, high-purity gas is required for analytical purposes

Safety precautions for high-purity helium gas:

1. Closed operation, providing good natural ventilation conditions.

2. Operators must undergo specialized training and strictly follow operating procedures.

3. Prevent gas leakage into the workplace air.

4. Keep away from flammable and combustible materials.

5. Handle with care during transportation to prevent damage to steel cylinders and accessories; Equip with emergency response equipment for leaks.

6. Store in a cool and ventilated warehouse; Stay away from sources of fire and heat; The storage temperature should not exceed 30 ℃.

7. It should be stored separately from flammable materials and avoid mixing storage. Generally, no special protection is required.

When the oxygen concentration in the workplace air is below 18%, air respirators, oxygen respirators, or long tube masks must be worn.

9. Bottled gas products are high-pressure filling gases, which should be depressurized before use.

10. The packaged gas cylinders have a service life, and any expired gas cylinders must be sent to a department for safety inspection before they can continue to be used.

11. When using exhaust gas in each cylinder, the residual pressure inside the cylinder should be kept at 0.5 MPa, and the minimum residual pressure should not be lower than 0.25 MPa. The cylinder valve should be closed to ensure gas quality and safe use
