(OP)
Hi All,
Looking for some guidance on the best materials to use for Sulfuric Acid pipework transfer, and diluted but low pH mixture. There are two operating conditions:
1) 98% Sulfuric Acid injection to a tank - ambient temp but tank is heated w/steam to approx 90-100 deg C therefore can consider some heat transfer, particularly at the connection point/flange
2) Highly acidic (pH 2) Acid Water and Acid Oil pipelines (following injection of H2S04) at 100 deg C, roughly 5% dilution of sulfuric acid in the mix.
Pipeline velocities <2m/s
For background info the application is an oil soapstock splitting plant
Appreciate any help

hot, very acidic fluid - Internal plastic type linings won't like it much from the temperature point of view, you're definitely into exotic materials if you don't have a liner.
Remember - More details = better answers
