Governing Standards for Hydrochloric Acid (HCl) Service

ASME B16.34NACE MR0103API 607 (fire safe)ISO 15848 (fugitive emissions - toxic service)

What to Avoid in Hydrochloric Acid (HCl) Service

  • Carbon steel or ductile iron bodied valves
  • Any SS 304 or 316 in contact with fluid
  • Bronze, brass, copper alloys

Service Considerations

  • Toxic - ISO 15848 Class A or B fugitive emission requirement
  • All vents must go to scrubber
  • No copper alloy in any gasket, stem packing, or instrument connection
  • Dilution generates significant heat
  • Vapour phase is as corrosive as liquid - valve bonnet must be lined
