Why do oxygen and acetylene cylinders explode?

Oxygen cylinders and acetylene cylinders are indispensable gas source equipment in industrial operations, and their safety issues are extremely important. The correct storage, handling and use of these cylinders is not only related to production efficiency, but also the cornerstone of protecting personnel's lives. Ignoring the safety of cylinders may cause serious accidents such as fires and explosions, with disastrous consequences. Therefore, it is the unshirkable responsibility of every operator to strictly abide by the safety regulations of cylinders, conduct regular inspections and maintenance, and ensure that the cylinders are in good condition.

Acetylene cylinders are filled with fillers and solvents (acetone). When placed horizontally for use, acetone is easy to flow out with the acetylene gas, which not only increases the consumption of acetone, but also reduces the combustion temperature and affects the use. At the same time, it will cause backfire and cause acetylene cylinder explosion accidents. The acetylene in the cylinder is dissolved in the acetone solvent under pressure. When the valve is opened, the pressure is reduced, and the dissolved acetylene is released as gas. When the acetylene cylinder is placed horizontally, it may cause acetone to flow out. The acetylene dissolved in acetone will evaporate quickly and mix with air to form an explosive mixture. The explosion limit is: 2.3%-72.3% (vol), the minimum ignition energy is: 0.019mJ, and it will cause combustion and explosion when encountering open flames and heat energy. It not only increases the consumption of acetone, but also reduces the combustion temperature and affects the use. At the same time, it will cause backfire and cause acetylene cylinder explosion accidents; in addition, the pressure in the bottle will blow out the solvent and dissolved acetylene, which will directly cause the acetylene pressure to increase and explode.

When acetylene cylinders are placed horizontally, they are easy to roll. Once bottles collide with each other or with other objects, energy will be stimulated, causing the acetylene cylinders to explode.

Acetylene cylinders are equipped with shockproof rubber rings to prevent collisions during loading, unloading, transportation and use. The rubber ring is an insulating material. Placing the acetylene cylinder horizontally is equivalent to placing it on an electrical insulator, so that the static electricity on the cylinder cannot spread to the ground. Otherwise, static electricity will accumulate on the cylinder and easily generate sparks. When acetylene gas leaks, it is very easy to cause combustion and explosion accidents.

The acetylene cylinder valve is equipped with a pressure reducer, a flame arrester 9, and is connected to a hose. Because it is easy to roll when placed horizontally, the pressure reducer, the flame arrester, or the hose may be damaged or pulled off during rolling, causing acetylene gas to leak out, leading to combustion and explosion.

EX gas cylinder cabinet

The whole cabinet is made of 1.2mm thick high-quality cold-rolled steel plate, and the surface is electrostatically sprayed with epoxy resin. There are gas pipe pass holes on both sides of the cabinet to adapt to the height of the gas cylinder. It adopts explosion-proof gas detectors, which can identify most flammable gases and have explosion-proof certification. It is equipped with explosion-proof sound and light alarm devices. When the sensor in the cabinet detects gas leakage, it will automatically alarm. The flammable gas cylinder storage cabinet is equipped with an automatic interlocking strong exhaust fan, which is discharged to the outside through the exhaust pipe. Toxic gases are connected to the absorption and treatment device through the exhaust pipe to ensure the personal safety of the working area.
