Application of high-purity helium gas

High-purity helium gas finds wide-ranging applications across multiple technical and industrial fields, with key professional use cases as follows:

1. Aerospace & Military

Propellant pressurization for rockets and missiles (ensures stable fuel delivery due to inert properties).

Leak detection in aircraft fuel systems, satellite propulsion components, and military weaponry (utilizes small molecular size for high sensitivity).

Cryogenic cooling for avionics, infrared detectors, and military radar systems (boiling point -268.9°C for ultra-low temperature requirements).

2. Industrial Manufacturing & Engineering

Arc welding of high-performance alloys (e.g., stainless steel, titanium) in aerospace and nuclear industries (provides inert shielding to prevent oxidation).

Semiconductor fabrication (purge gas for wafer processing, cooling of ion implanters, and carrier gas in chemical vapor deposition).

Heat treatment of precision components (maintains uniform temperature and prevents material contamination).

3.Scientific Research & Laboratory

Cryogenics for superconducting magnets (e.g., MRI machines, particle accelerators) – liquid helium enables superconductivity.

Gas chromatography (carrier gas for high-resolution separation of chemical compounds).

Calibration of analytical instruments (standard reference gas for precision measurements).

4. Energy & Nuclear Industry

Cooling of nuclear reactor components (thermal conductivity and inertness ensure safety in high-radiation environments).

Leak testing of natural gas pipelines and LNG storage facilities (non-flammable and non-toxic properties).

5. Electronics & Advanced Technology

Thermal management of high-power electronic devices: used for heat dissipation of laser diodes, power semiconductors and other devices, with high thermal conductivity and non conductivity, to avoid equipment overheating and damage.

Fiber optic manufacturing: Blow air during the fiber optic fusion and drawing process to prevent impurities from entering and ensure the optical transparency and transmission performance of the fiber optic.
