Design of heptafluoropropane storage tanks

Heptafluoropropane (HFC-227ea/FM200) is a clean gas fire extinguishing agent that relies primarily on chemical mechanisms for extinguishing fires, with additional physical effects as well; it belongs to the category of polyfluoroalkanes, and its molecular formula is C3HF7； It is colorless, tasteless, low in toxicity, non-conductive, does not contaminate the objects it protects, and causes no damage to property or precision equipment. Heptafluoropropane can reliably extinguish Class B, Class C fires, and electrical fires at relatively low fire suppression concentrations ； It has a small storage volume, a high critical temperature, and a low critical pressure; it can be liquefied and stored at room temperature ； After release, it contains no particles or oily residues, causes no damage to the atmospheric ozone layer (ODP value is zero), and its residence time in the atmosphere is 31–42 years, meeting environmental protection requirements.
