IG541 is a common gas fire extinguishing product, which uses a fire extinguishing agent that is a mixture of nitrogen, argon and carbon dioxide in the atmosphere, which naturally exist in the atmosphere, so its greenhouse effect is zero and the ozone layer depletion potential is zero. There will be no chemical reaction when extinguishing the fire, no pollution of the environment, non-toxic, non-corrosive, good electrical insulation performance, clean fire extinguishing process, no trace after fire extinguishing will not pose a hazard to the protected equipment. IG541 gas fire extinguishing systemThe working pressure is up to 172MPa, so it is more suitable for large space, long-distance protection, large use, and units with extremely high requirements for fire extinguishing, such as large data rooms, communication rooms, archives and other key protection areas. So how often is the IG541 gas cylinder tested, is there a specific specification, presumably many people are not very clear, the following Shengshi Zhi'an shared the relevant regulations with you, let's take a look!
1. The detection cycle of IG541 fire extinguishing system
IG541 fire extinguishing system has high storage pressure, a large number of gas cylinders, a large area between the cylinders that need to be used, and its working pressure is also higher, according to the General Administration of Quality Supervision, Inspection and Quarantine of China promulgated the "Pressure Vessel Technical Supervision Regulations" IG541 gas cylinders belong to pressure vessels, according to the "Gas Cylinder Safety Technical Supervision Regulations" TSGR0006 mandatory pressure vessel regular inspection system. It is stipulated that the testing cycle of fire extinguishing cylinders (heptafluoropropane, high-pressure carbon dioxide, IG541) is 3 years, and nitrogen cylinders are inspected every 5 years.
2. Inspection cycle of IG541 fire extinguishing system
The specifications for the periodic inspection cycle of fire cylinders in the "Regulations for the Safety and Technical Supervision of Gas Cylinders" are as follows:
7.4.1. Inspection cycle of various types of gas cylinders.
The inspection cycle of gas cylinders shall not exceed the provisions of this article.
Article 74.1.Article 1 stipulates that steel seamless cylinders, steel welded cylinders, aluminum alloy seamless cylinders:
1) Contains nitrogen, sulfur hexafluoride, inert gas and purity greater than or equal to 99999% non-corrosive high-purity gas cylinders, inspected once every 5 years;
2) Gas cylinders containing gases that can produce high corrosive effects on the cylinder material, diving cylinders and gas cylinders that are often in contact with seawater shall be inspected once every 2 years;
3) Gas cylinders containing other gases shall be inspected once every 3 years.
The test period of the gas cylinder containing the mixed gas shall be determined according to the gas with the shortest test cycle in the mixed gas.
From the above, it can be seen that the regulations clearly stipulate that the testing of IG541 gas cylinders is tested once every 3 years.
3. Precautions for testing IG541 gas cylinders
1. The gas cylinder transportation vehicle must be safe and reliable.
2. Wear bottle caps, shockproof rings, light loading and unloading for gas cylinders, and it is strictly forbidden to throw, slip, roll and touch.
3. When hoisting, it is strictly forbidden to use electromagnetic cranes and metal chain ropes.
4. Gas cylinders that will cause combustion and produce poisons when the gases in the cylinders come into contact with each other cannot be transported in the same compartment, and flammable and corrosive materials or items that have a chemical reaction with the gas in the cylinders cannot be transported together with the gas cylinders.
5. When using vehicles for transportation, the gas cylinder should be properly fixed, and the height of the compartment should be more than two-thirds of the height of the bottle when it is placed vertically, and the valve end of the cylinder should be facing the other direction when lying down.
6. If the transportation is in summer, there should be shading facilities to avoid exposure to the sun, and daytime transportation should be avoided in areas with a lot of traffic in the city.
7. The gas cylinder has high requirements for the safety of storage, and it should not be placed in a sun-exposed area after arriving at the testing station, and it must be safe when storing.
To sum up, how often do IG541 gas cylinders be tested, and whether there is any specific specification of all the content, we will be clear after reading it, if there is anything unclear, you can leave a message in the comment area, or leave a message in the comment area, and answer in detail for you!
