Material selection for mixed acid pumps in digestion reactions
Thread Content
Dear seniors, does anyone know what material would be suitable for use at a temperature of 100 degrees Celsius, in a mixture of 70% sulfuric acid and 3% *AO acid?
Currently, ALLoy20 has poor corrosion resistance
Material selection for mixed acid pumps in digestion reactions?*ao Acidification reactions?
Perfluorine is chosen for such harsh operating conditions. If metals are to be used, tantalum and tantalum-tungsten alloys are required.
For non-metallic materials, PTFE lining is sufficient
The original poster, I can help you. I specialize in these types of pumps; to prevent corrosion when 70% concentrated sulfuric acid is flowing at high speeds, it’s necessary to use steel-lined PTFE materials. Additionally, *ao acid will corrode ordinary rubber seals, causing leaks, so acid-resistant components need to be used instead. You can call to discuss it in detail.
