Welding & Metal Fabrication
Carbon dioxide is most often mixed with argon as a shielding gas used to prevent atmospheric contamination of molten metal in electric arc welding processes.
Chemical:
Carbon dioxide is used in synthesis chemistry and for controlling reactor temperatures.
CO2 is also employed to neutralize alkaline effluents.
Carbon dioxide is used under supercritical conditions for purifying or dying polymer, animal or vegetal fibers.
Pharmaceuticals:
Carbon dioxide is used for inerting, chemical synthesis, supercritical fluid extraction, acidification (pH) of wastewater or product transportation at low temperature (-78 ºC or -108 ºF).
Healthcare:
CO2 produces close-to-physiologic atmospheres for the operation of artificial organs.
Carbon dioxide is used as a component in a mixture of oxygen or air as respiratory stimulant to promote deep breathing. It is also used for the surgical dilation by intra-abdominal insufflations.
Metal industry:
Carbon Dioxide is typically used for environment protection:
• CO2 is used for red fume suppression during scrap and carbon charging, for nitrogen pick-up reduction during EAF tapping and for bottom stirring.
• In the non ferrous metallurgy, carbon dioxide is used for fume suppression during ladle transfer of matte (Cu/Ni production) or bullion (Zn/Pb production).
• Small amount of liquid CO2 can be used in recycling of waters from Acid Mine Drainage.
• The well known CO2 lasers are feed with some special grades of carbon dioxide.
Laboratories and Analysis:
Supercritical CO2 is the mobile phase in both chromatography and extraction applications.
Pulp and paper:
Carbon dioxide enables to sharply tune the pH of recycled mechanical or chemical pulps after an alkaline bleaching.
Q1. What's the MOQ?
A:Different products have different MOQ,Pls feel free to contact with me directly for your requirement.
Q2:What is the delievery time?
A:Depends on your quantity.Normally it will cost 7-10 days for preparation.
Q3:What is the package, storage& transportation details?
A:Package:Steamless steel cylinder with different valves,or as to your requirement.
Stored in shady, cool, dry, eventilated warehouse, and keep away from sunlight and any ramming.
Q4:What is the payment terms?
A:30% T/T in advance, balance against the B/L.
Q5:How to check gas quality?
A: Before filling the gas, the cylinder will be treated carefully, such as cleaning, drying, vacuum pumping and replscement.
Then, we will take tests every treated cylinder to assure them inside purity.
Thirdly, we will take a test for all the gas after fill into the cylinder, to make sure the quality of the gas along with the tested reported.
Q6: If the cylinder recycled and can be refilled gas again?
A: Yes, usually the seamless steel cylinder can recycle to use for 20 years, and also can be refill gas again.
But , when you ordered our cylinder, you have to inform us before exporting, we will handle all the import customs clearance formalities.
Q7:Why choose us?
A: Fast delivery, Factory price and soonest reply within 24 hours.
