An L-type pneumatic three-way ball valve made of 316L material is installed on the pipeline carrying high-acid media at high flow rates (acidity of 50%) to enable switching; is this reliable?
Consult corrosion manuals, such as the Ullig Corrosion Manual, published by the Mechanical Industry Publishing House in 2005
What is the temperature at a 50% concentration? 316L seems a bit tough.
316L has a certain degree of corrosion rate, which varies depending on temperature and pressure conditions; if these levels are not high, plastic valves can be considered as they offer better corrosion resistance
Valves made of Hastelloy must be quite expensive, right?
When the temperature is below 180 degrees Celsius and the pressure is below 16 kilograms, a steel-lined PFA material can be considered; it offers corrosion resistance and is cheaper than titanium or Hastelloy
If the temperature and pressure are not high, valves with PTFE linings can be used
