Governing Standards for Sulphuric Acid (H₂SO₄) Service
What to Avoid in Sulphuric Acid (H₂SO₄) Service
- Bronze or brass-bodied valves
- Standard SS 316 for concentrated acid above 20%
- Rubber-lined valves (except EPDM in specific concentrations)
Service Considerations
- Always design for double containment or secondary containment
- Emergency shower and eyewash must be immediately accessible
- Full-bore valves preferred to minimise turbulence and localised attack
- Dilution point design must prevent acid-in-water splashback
- ATEX rating required where sulphur vapours present
