Dear acid industry professionals, what material is used for the acid transfer pipes inside the dry absorption tanks in your respective sulfuric acid plants? What is the material that is commonly used these days? ?
Cast iron corrodes rapidly in the circulation tank
Pure PTFE pipes can be considered
The acid-through sleeve for low-chromium cast iron is quite good
Imported alloy materials corrode and passivate slowly, and their prices are quite high
Three towers and one tank, without acid interconnection pipes
Cast iron pipes for acid transfer can last for several years without failing, while pipes used for water are more prone to damage. We use PTFE hard pipes
They are made of white steel: the pump outlet pipelines, the acid coolers, as well as the pipelines leading back to the tower. The pipelines from the tower to the dry absorption tank are made of cast iron
