Carbon dioxide cylinders will explode. Carbon dioxide cylinder is a kind of pressure vessel. Under high temperature or impact, its pressure will exceed its bearing limit and explode. The explosion will cause the safety valve to be pushed open and the gas will leak. When using carbon dioxide cylinders, the ambient temperature should not exceed 30 degrees as far as possible, and the volume of the cylinders should not exceed 70% when inflated, and they should not be placed upside down or horizontally.
The explosion was caused by electrochemical corrosion. Most gas cylinders are unqualified oxygen cylinders, and they are very old. Water is brought into the filling process to lubricate the compressor cylinder, which provides good conditions for acid chemical corrosion and electrochemical corrosion of the gas cylinder. With the increase of service life and long-term vertical use, the two kinds of corrosion alternate, making the gas cylinder in a state of dripping water and wearing stones.
Matters needing attention in using carbon dioxide cylinders:
1, carbon dioxide cylinders with design pressure of 125 kg/cm2 will be phased out year by year, and high-pressure liquefied carbon dioxide cylinders with design pressure of 150 kg/cm2 and 200 kg/cm2 will be adopted.
2. Unqualified oxygen cylinders or other modified carbon dioxide cylinders are strictly prohibited.
3. It is forbidden to expose cylinders and ignite cylinder valves. The gas cylinder should be far away from the heat source, and its external paint color should be aluminum white to weaken the influence of radiant heat.
4. When filling a bottle, the accumulated water in the bottle must be removed regularly.
5, regular inspection, should remove the loose rust on the cylinder wall.
6. The inner wall of the gas cylinder can be covered with a layer of anticorrosive material, such as perchloroethylene acid-resistant paint.
