1. Will oxygen cylinders explode?
Oxygen cylinders are high-pressure containers used to store and transport oxygen. If safety management is not in place, explosion accidents may easily occur.
The explosion of an oxygen cylinder is a physical explosion. The gas pressure is too high and the shell cannot withstand it and explodes. There are generally two ways to increase the pressure: one is to inflate the gas inside, and the other is to increase the temperature. In view of the thickness of the oxygen bottle, it is very difficult for households to meet the conditions for the oxygen bottle to explode, so oxygen bottles generally do not explode.
However, if the pressure valve of the oxygen cylinder is close to full and a fire occurs at this time, the temperature during the fire is generally above 800°C. It is easy for the oxygen cylinder to explode and the oxygen stored in it to escape, and the oxygen will support combustion. causing the fire to further expand.
2. What is the cause of the explosion of oxygen bottles?
The danger of explosion of oxygen bottles is very great. Generally, the possible reasons for the explosion of oxygen bottles are as follows:
1. Improper oxygen filling
The correct filling of gas cylinders is a key link to ensure the safe use of gas cylinders. When an explosion accident occurs due to improper filling, has happened. The most dangerous factor in this regard is the use of cylinders containing flammable gases (such as hydrogen) to fill oxygen and overfilling of oxygen.
2. The material and manufacturing quality of the oxygen cylinder do not meet the requirements.
During the filling and use of oxygen, explosion accidents often occur. In this regard, The main manifestations are that the material used to make the gas cylinder is fragile, the thickness of the bottle wall is uneven, and there are interlayers in the bottle body.
3. Improper maintenance and storage of oxygen bottles
Mainly due to serious corrosion of the bottle body or exposure of the oxygen bottle to the hot sun for a long time during use. Or bring the oxygen cylinder close to a high-temperature heat source, which is a common direct cause of oxygen cylinder explosions.
4. The oxygen cylinder is not tightly sealed
The oxygen cylinder valve is not protected by a bottle cap, is subject to vibration, or is used improperly, resulting in loose sealing and leakage. , or even the bottle valve is damaged, causing high-pressure oxygen to rush out and cause a combustion explosion.
5. Oxygen cylinder accessories are sticky with oil
Oxygen cylinder valves or other accessories (such as valve stems, pressure reducers) stained with grease often cause In a fire accident, when oxygen is sprayed out rapidly, the grease will quickly oxidize, and the heat generated by the friction between the high-pressure air flow and the bottle mouth will further accelerate the oxidation reaction.proceed, causing an explosion.
3. How powerful is the explosion of oxygen cylinders
Oxygen cylinders are high-pressure gas cylinders, and their explosion power is very large because they contain high-pressure oxygen. , the explosive power of a bottle of gas cylinder is ≈ 145 kilograms of TNT explosive. One kilogram of TNT explosive can almost blow up a two-story bungalow. The power of a gas explosion equivalent to 145 kilograms of TNT can be imagined.
In addition, because oxygen bottles store oxygen, and the oxygen itself has a combustion-supporting effect, explosion accidents often cause fires, causing greater harm.
4. How to avoid oxygen tank explosions
To prevent oxygen tank explosions, there are three main points:
1. Ensure Do not overpressure the oxygen tank. There are two points here: do not overfill when filling, and when using, the ambient temperature should not be higher than the temperature allowed for use (sun protection, anti-scalding, fire protection, etc.). The fire may not be caused by the explosion of the oxygen tank, but it may The fire may have caused the oxygen tanks to explode one after another).
2. To ensure the quality of the oxygen tank, this must be checked regularly. Aged or damaged oxygen tanks must be replaced in time.
3. Handle it with care, and fix it when placing it to prevent it from falling, damaging a certain part, causing oxygen leakage and causing “flying bottle”.
