How often are fire cylinders tested? Gas fire extinguishing system (IG541, HFC-227EA, carbon dioxide, etc.) has become increasingly common in the application of various industries. Key protection areas such as library archives room, information computer room and power distribution room have been protected by gas fire extinguishing system. In the long-term use of fire cylinder, the cylinder will become thin due to corrosion caused by external pollution, and will also crack due to corrosion of the cylinder by water or other impurities in the cylinder. In case of high heat, the pressure inside the container will increase, and there is the risk of cracking. According to the national fire regulations, fire cylinders must be tested regularly.
According to the General Administration of Quality Supervision, Inspection and Quarantine of the State issued the "Gas cylinder Safety Technical Supervision Regulations" clearly requires that fire cylinders must be tested regularly. The rules are as follows:

Article 7.4.1.1 states that steel seamless gas cylinders, steel welded gas cylinders, aluminum alloy seamless gas cylinders:
(1) Gas cylinders containing nitrogen, sulfur hexafluoride, inert gas and non-corrosive high-purity gas with purity greater than or equal to 99.999% shall be inspected once every 5 years;
(2) Gas cylinders containing gases with high corrosion effect on cylinder materials, submersible gas cylinders and gas cylinders often in contact with seawater shall be inspected once every two years;
(3) Gas cylinders containing other gases shall be inspected once every three years.
Clause 7.5 provides for prior inspection
In the course of using the gas cylinder, if any of the following conditions are found, regular inspection shall be conducted in advance;
(1) There is serious corrosion or damage or there is doubt about its safety and reliability;
(2) The winding layer of the wound gas cylinder is seriously damaged;
