Stable High-Purity Helium Gas Sourced from Qatar/Russia/China, Packaged in Gas Cylinders and Tube Trailer
Helium (He) is a chemical element with unique properties that make it invaluable in various applications. It is a colorless, odorless, and tasteless gas that is non-toxic and non-flammable.
Basic Properties
- Chemical Symbol: He
- English Name: Helium
- Appearance: Colorless and odorless gas
- Density: 0.1785 g/L at 0°C (much lower than air, which has a density of 1.29 g/L)
- Melting Point: -272.2°C
- Boiling Point: -268.934°C
- Solubility: Slightly soluble in water; insoluble in ethanol
- Helium is an inert gas, meaning it has very low reactivity and does not form compounds easily with other elements.
- It is the second most abundant element in the universe, accounting for about 25% of the universe's mass (after hydrogen).

Applications
- Cryogenic Cooling: Due to its extremely low boiling point, liquid helium is used for cryogenic cooling in applications such as superconductivity.
- Balloon Filling: Helium is often used to fill balloons and airships because it is lighter than air and non-flammable, making it safer than hydrogen.
- Protective Gas: In welding processes, helium can be used as a protective gas to shield the weld area from oxygen and other contaminants.
- Semiconductor Industry: Helium is essential in the semiconductor industry for processes such as etching and ion implantation.
- Other Applications: Helium is also used in high-vacuum apparatus, nuclear reactors, as a pressurizing gas for liquid hydrogen and liquid oxygen in rockets and spacecraft, and as a filling gas in gas thermometers.
We adheres to a stringent quality system to ensure product quality, stability, and reliability.
1. From contract signing to product delivery,
we ensure
"three guarantees":
Stable Supply Guarantee: Ensuring a consistent and reliable source of raw materials to maintain uninterrupted production.
Quality Excellence Guarantee: Committing to delivering products of the highest quality standards.
Timely Delivery Guarantee: Guaranteeing that products are delivered to customers on time, meeting or exceeding their expectations.
2. From raw materials to finished products,
we adhere to the GB/T4844-2011 National Standard for High Purity Helium and conduct
"four analyses" for index control:
Comprehensive Raw Material Entry Analysis: Ensuring all incoming raw materials meet specified criteria.
Complete Base Gas Analysis: Analyzing the base gas to maintain consistency and quality.
Online Comprehensive Raw Material Analysis: Continuously monitoring raw material quality during production.
Finished Product Comprehensive Analysis: Verifying that every finished product meets or exceeds set standards.
3. For finished products,
we implement a warning value system that surpasses national standards to ensure a 100% pass rate before shipment.
From container entry to exit, we follow the
"Five Inspections" based on the Safety Technical Regulation for Gas Cylinders:
Initial Container Reception Inspection: Checking containers upon arrival for any initial defects.
Pre-Filling Inspection: Conducting a thorough examination before filling to ensure container safety and suitability.
In-Filling Patrol Inspection: Monitoring filling processes for any abnormalities or safety hazards.
Post-Filling Inspection: Verifying that the filling process was completed correctly and that containers are sealed properly.
Pre-Shipment Inspection: Final check before dispatch to ensure all containers are in good condition and ready for transportation.
Any unqualified containers identified during the "Five Inspections" are promptly reported and, upon agreement, undergo necessary repairs or replacements before being refilled. Containers that do not meet filling requirement are not processed.
4. Products leaving our facility carry
"two signatures, one certificate, and one manual":
Two signatures: Quality assurance and inspection signatures
One certificate: Compliance certificate
One manual: Product usage and safety manual
Our company operates under the ISO9001 Quality Management System, with full employee participation. We use systems, processes, and standards to prevent non-conformities, guide proper form filling and record-keeping for data traceability, and satisfy post-sales product requirements. Regular personnel capability evaluations and training are conducted to provide customers with even more professional and optimal product solutions, adhering to our business philosophy of "meeting customer needs with unparalleled quality and value."
