How long will the gas bottle explode in the sun?

There is no exact time for the cylinder to explode in the sun, because the temperature tolerance limit of the cylinder depends on many factors, including temperature, sunshine intensity, material of the cylinder, internal pressure and so on.

Generally speaking, when a gas cylinder is exposed to sunlight, the following situations may occur:

1. Internal pressure increase: the gas pressure in the gas cylinder will increase with the temperature increase. If the internal pressure exceeds the bearing limit of the gas cylinder, it may lead to explosion.

2. Material deformation: If the gas cylinder is exposed to high temperature for a long time, the material of the cylinder may be deformed, thus affecting the safety of use.

3. Valve failure: At high temperature, the valve of the gas cylinder may also be affected and fail, resulting in gas leakage or pressure increase.

Therefore, in order to ensure safety, please do not expose the cylinder to the sun, especially in high temperature weather. If you must use gas cylinders, please put them in a cool place and pay attention to timely inspection and maintenance to ensure safe use.
