Selection of flowmeter lining for low-concentration sulfuric acid
Thread Content
The wastewater currently contains 12 g/L of sulfuric acid, with a temperature ranging from -30°C to 30°C and a pressure of 800 kPa_g. Is it acceptable to use polyurethane or hard rubber in this case? Due to certain constraints, it is not possible to use other types of linings. I seek guidance from the experts! ! !
Polyurethane and hard rubber tend to expand over time; it’s better to consider PTFE instead
No problem; either stainless steel or polyester is fine
Choose PTFE for a one-time solution; other options won’t save that much money – why go the extra effort? !
Choose PTFE if it’s less than 200 degrees.
