How long does heptafluoropropane gas expire?
The validity period of heptafluoropropane medicament itself is one hundred years, a long time. According to China's "Gas Cylinder Safety Technical Supervision Regulations", it is explicitly stipulated that the service life of seamless steel splicing gas cylinders is 30 years, and the service life of welded steel gas cylinders is 20 years. The validity period of heptafluoropropane is much longer than the service life of the gas cylinder. The shelf life of heptafluoropropane gas cylinder machinery and equipment generally depends on the characteristics and quality of the gas cylinder, and generally ranges from 20 to 30 years. And according to technical specifications, gases such as heptafluoropropane, IG541, and high-pressure carbon dioxide gas cylinders are inspected every three years. If you find a manufacturer specializing in producing heptafluoropropane, you can usually conduct steel cylinder inspection, and nitrogen cylinders are inspected every five years. Ensure that there are no leaks, damages, or other issues with the gas cylinder. When the working pressure of the machine equipment is insufficient, the needle of the pressure gauge is not in the green area, indicating a leakage of heptafluoropropane fire extinguishing agent. The gas cylinder must be sent to a professional manufacturer of gas fire extinguishing equipment for inspection of its sealing, and heptafluoropropane must be filled here.
