99.999% 40L Steel Bottler ISO Standard Helium Cylinder

99.999%High purity helium
Main application: used in the study of ultra-low temperature, gas chromatography analysis, non-ferrous metal welding, leak, chemical gas phase deposition, crystal growth, the configuration of the plasma dry, special mixture, used as a standard gas, gas balance,medical gas, inflatable balloon, tube, diving suits, etc.NINGBO DSW INDUSTRY CO.,LTD established in 1998. Our company possesses five production lines for production of various seamless gas.Our major products are oxygen cylinder, nitrogen gas cylinder, carbon dioxide gas cylinder, argon gas cylinder, other industrial gas cylinder, medical oxygen gas cylinder supply unit, etc., cylinders. 

In order to open the cylinder market, our company now launched the following gas: 99.999% and 99.995% helium were 99.9% and 99.999%, 99.9% and 99.999% of the laughing gas, the carbon monoxide were 99.9993% and 99.999%, 99.9993% and 99.999% of argon gas, and 99.995% hydrogen, 99.995% and 99.999% nitrogen, 99.999% and 99.99% were 99.999% and 99.995% and 99.999% of carbon dioxide, methane, 99.999% and 99.998%, and 99.999% of the oxygen, or more than 99.9% of acetylene, and so on.



Our quality is strictly controlled from the very beginning, only a strict quality control in every working procedure, to ensure that each bottle of gas purity and quality.Choose in the cylinder production 100% new high quality seamless steel pipe from Bao Shan Iron co., LTD (Baosteel).

From raw material selection to the cylinder processing to gas detection, every step we are strictly controlled
1.On raw material processing: first we chromatographic purity test at the meeting, the purity standard again after unloading into the tank, before purification purification.

2. Before filling: heating with the first step of the cylinder, the second step is to dry the moisture inside the cylinder, the third step to open the cylinder calabash valve pumping air into vacuum state, the fourth step play 0.3 to 0.5 mpa raw material gas chromatography to test, test impurities, this step is to test both sides can enter the next step aeration process.


3.The cylinder after the above processing, filling in the filling line.

4. After the completion of the filling: in each of the cylinders for purity test, purity is not qualified cylinders for processing, no shipment.
pay attention to that before use, please open a little bit of the valve and blew the ash off the valve and piping on the grey, because impurities affect the purity of bottle.
 Being a professional manufacturer of gas cylinders, we can produce high-quality seamless steel gas oxygen cylinders from 2L to 68L with different stadard specifications as per your kind request(s). If any interests or some more info needed, pls feel free to contact us! 99.999%High purity helium
