Welding co2 description

Yuantong gas has a history of nearly 23 years in industrial CO2  which is established on year 1995. Carbon dioxide is a compound containing carbon and oxygen. At atmospheric temperatures and pressures, carbon dioxide is in gaseous form. It is colorless, odorless, about 1.5 times heavier than air and a slightly acid gas. The gas is nonreactive, nontoxic and nonflammable. Solid carbon dioxide (dry ice ) is formed at a temperature of -78.5℃.

FAQ

1. How can i get to your factory?

A:Our factory is near shanghai Airport, we can pick you up in the airport. 

2. If i will need to stay in your place for few days, is that possible to book the hotel for me?

3. About the after-sale service, how can you solve the problems occurred of your overseas customer in time?

A:The warranty of our machine is normally 12 months, during this period, we will arrange the international express immediately, to make sure the replace parts to be delivered as soon as possible.  

4. What’s the delivery time?

A: If the cylinder is in the stock, and only need to fill gas, the delivery is about 7-10 days ex work after receive the deposit.

If the cylinder need to customize, the delivery is about 15-35 days ex work after receive the deposit. That is depends on the quantity.

5. How to check the gas quality?

A: Firstly, our cylinder will take a treatment (cleaning, drying, vacuum pumping, and replacement before filling gas. In this way, the cylinder inside is clear and dry. Secondly, we will take tests every treated cylinder to assure them inside purity. Thirdly, we will take a test for all of the gas after fill into cylinders. If the tested gas is not up to standard, we will produce it again and not release the faulty product to ex work. At last, we will supply you the gas test qualified report.
