Fluorine-lined valves are used to deal with acidic liquids such as hydrochloric acid, concentrated sulfuric acid, and hydrofluoric acid. They are not afraid of even aqua regia, which can melt stainless steel into slag.
The benefits of using fluorine-lined valves are as follows:
1. Fluoroplastics (such as F46 and F3) are naturally corrosion-resistant. When strong acids and alkalis are poured on them, it is like a tickle. They are much more durable than stainless steel.
2. The metal shell is responsible for bearing pressure, and the plastic lining is responsible for corrosion resistance. The two work together without getting tired. It’s like a tough guy wearing a bulletproof vest, which can both fight and resist.
3. Although fluoroplastics are expensive in themselves, the cost of fluorine-lined valves is directly cut in half compared to pure titanium alloy valves. The boss of the chemical plant exclaimed that it is really good.
Fluorine-lined valves are the gas masks in the chemical pipeline industry – they specialize in dirty and tiring work. From sulfuric acid pools to potion workshops, wherever there is corrosive liquid flowing, there are them standing guard! ‌
