Available for download

This standard practice is intended to provide guidance to those designing, fabricating, and/or maintaining refinery equipment and piping that are exposed to caustic environments.

Caustic is used in many petroleum refinery applications in a wide range of concentrations and temperatures.  Caustic stress corrosion cracking (SCC) of carbon steel (CS) equipment has been reported in industry since the 1930s, e.g., in riveted steam boilers.  NACE has published guidance for handling sodium hydroxide (NaOH) in the form of a “Caustic Service Chart” since at least the mid-1960s.
