For spent caustic (pH > 7) and for neutralized caustic (ph 5.5 – 6.5
i.e. slightly acidic pH), LTCS A333-6 pipe material,  2 mm CA

When more acid is likely (i.e. for acid solution or acid + caustic
mixture upstream of neutralization vessel  when neutralization is not
complete), PTFE lined LTCS

Please note that LTCS is used because of ambient temperature in
Kazakhstan during winter.
