Frequently asked questions

Q:Can the gas cylinder be customized?

A:Yes, we can customize production according to customer needs.
Q:How long is the lead time for gas cylinders from order to delivery?

A:The whole cycle from design, production to testing takes about two months. It can be delivered worldwide and provide after-sales support.
Q:How to determine whether a gas cylinder needs to be scrapped or replaced?

A:The bottle body is dented, cracked, severely rusted, or the coating has fallen off in a large area. The pressure drops abnormally after inflation, and the valve cannot open and close normally. Or the material strength is found to be substandard during testing.
