1, the cylinder is too full;

2. When changing the gas tank, the regulator fails and explodes because the regulator is not tightened or the sealing ring is aging, and the connector leaks and ignites the connector;

The cylinder can still work in spite of illness. When the gas cylinder is used for a long time, it will corrode, perforate and crack, resulting in the loss of compressive strength. In case of high temperature, it is easy to explode due to extrusion or collision.
