Hello Everyone,
 

Glad to connect 
 

We are currently working with the storage and transfer of dilute hydrofluoric acid (50% by weight). However, we often face failures in equipment, valves, and instrumentation due to its highly corrosive nature.
 

I would be grateful if you could share your insights on how to handle such a corrosive fluid effectively, without compromising equipment integrity or product quality.

we  already use the PTFE coated  pipe line /valves/equipment.

A Google search:

 

 

A 50% hydrofluoric acid (HF) solution is highly corrosive and reactive. It's compatible with certain materials for short-term use, but long-term exposure requires careful selection. Materials like Teflon (PTFE), Kynar (PVDF), certain high-nickel alloys (e.g., Hastelloy C-276, Monel 400), and some specialized graphites are suitable for HF vapor service.
