Helium is a highly specialized product. It's chemically inert and non-flammable, with high thermal conductivity, low molecular weight and size, and the lowest boiling point known.
Applications:
Aerospace & Aircraft
From manufacturing to flight, helium is widely utilized throughout the aerospace and aircraft industry. In space flight operations, helium is used to purge hydrogen systems and works as a pressurizing agent for ground and flight fluid systems. It is also a source of lift in weather and other surveillance balloons.
Automotive & Transportation Equipment
Helium is used to test critical automotive parts such as radiator heat exchangers, air conditioning components, fuel tanks and torque converters to ensure they meet quality specifications. It is also used in combination with argon as a source of inflation in a growing number of airbags.
Diving
In combination with oxygen, helium is used in diving to help eliminate nitrogen narcosis, reduce breathing resistance at depth, and shorten decompression stops. Known as heliox, the mixture allows divers to reach greater depths for longer periods of time. The deeper the dive, the higher the concentration of helium, allowing divers to explore more and weld longer.
To ensure the 100% high quality products, we combined the automatic QC system and the manual inspection.
DCS (distributed control system) control the whole production process. DCS get and analyze the data from online inspection devices automatically every 15 minutes. There are online gas chromatography analyzer and moisture analyzer.
We have a inspection room to get more accurate data. we imported a Gow-Mac brand 826DID gas chromatography from the USA, and TIGEROPTICS brand micro moisture analyzer from Germany. Inspectors will inspect the gas every day for every shipment to make sure the gas quality is the best.
Q: What is the delivery time?
A:Generally we supply the goods within 45days after receipt of the deposit.
Q:What is your tems of payment?
A:T/T 30% as deposit, and 70% before delivery. We'll show you the photos of the products and packages before you pay the balance.
Q:Can your company produce my brand?
A:Yes, we can paint /engrave your company name or Logo on cylinder neck or cylinder body, and the cost is complimentary as long as receiving MOQ.
Q: How long is your delivery time?
A:Generally it's 30 days after receiving your advance payment, or the specific delivery time depends on the items and the quantity of your order.
