Will the gas cylinder explode?

Large oxygen cylinders usually explode, and the explosion of oxygen cylinders is not a chemical explosion, but a physical explosion. Physical explosion is an explosion when the gas pressure is too high for the shell to bear (try blowing a balloon). There are generally two ways to increase the pressure, one is to charge gas, and the other is to increase the temperature. However, in view of the thickness of the oxygen cylinder, it is difficult to meet the conditions for the oxygen cylinder to explode at home, so there is no need to worry at all.

However, it should be noted that if the pressure valve of the oxygen cylinder is close to full load, a fire will occur at this time, and the temperature during the fire is generally above 800℃, which makes it easy for the oxygen cylinder to explode. You know, oxygen is a perfect combustion improver, which can easily lead to further expansion of the fire. This is a potential safety hazard that must be paid attention to.

In order to ensure the safe use of oxygen cylinders, the state has successively promulgated the Regulations on Safety Supervision of Gas Cylinders, the Regulations on Safety Supervision of Dissolved Acetylene Gas Cylinders, the Regulations on Filling of Permanent Gas Cylinders and other laws and standards, which have made scientific and clear provisions on the design, manufacture, inspection, filling and use of oxygen cylinders.

1. The oxygen cylinders used must be produced by the designated national manufacturers. The new bottle must have the certificate of conformity and inspection certificate issued by the boiler and pressure vessel safety supervision department.

2. Oxygen cylinders must be inspected regularly according to regulations. It is forbidden to fill expired gas cylinders.

3. Oxygen cylinders are prohibited from contacting grease. Operators shall not wear overalls with excessive oil pollution, and shall not touch oxygen cylinders and their accessories with their hands, gloves and tools.
