Everyone has always attached great importance to the safe use of cylinders, but some people have encountered problems with cylinder explosions during use. Many people may have doubts. They have always been used in accordance with the principle of cylinders. Why is there an explosion? The following small series will tell you about the major reasons for the explosion of steel cylinders.
Due to the use of sunlight, open flames and heat radiation, the gas in the bottle is heated and the pressure is increased sharply until it exceeds the strength of the material of the cylinder, which causes the cylinder to deform or even explode. Because the bottle cap is not worn during handling, the hand-held bottle valve is lifted, or the impact is hit, the thread on the bottle neck or the valve body is damaged, and the bottle valve may be flushed out of the bottle neck by the pressure inside the bottle.
Oxygen cylinders can also explode in cold conditions due to falling or impacting explosions of hard objects during handling or storage. The accessories or bottle valves of the oxygen cylinder are stained by grease, and the oil fingers explode and oxidize and explode. The structure, process and materials of the manufactured cylinders do not meet the safety requirements, resulting in insufficient cylinder strength and explosion.
Oxygen cylinders or combustible or explosive gas cylinders, which are not discerned or identified after filling, are not strictly cleaned, and a mixed gas that produces a combustion explosion causes an explosion. The technical inspection was not carried out according to the cycle, and the explosion occurred due to the thinning of the bottle wall and the crack. Overfilling.
The oxygen cylinder especially the liquefied gas, is not filled as required, and the pressure is rapidly increased after being heated or subjected to shock during transportation.
The above is the reason for the explosion of the cylinder we introduced, so we must store it well, especially in the handling process, we should pay attention to avoid this situation.
