This International Standard establishes material requirements for resistance to SSC in sour petroleumrefining and related processing environments containing H2S either as a gas or dissolved in an aqueous(liquid water) phase with or without the presence of hydrocarbon. This International Standard doesnot include and is not intended to include design specifications. Other forms of wet H2S cracking,environmental cracking, corrosion, and other modes of failure are outside the scope of this InternationalStandard. It is intended to be used by refiners, equipment manufacturers, engineering contractors, andconstruction contractors.Specifically, this International Standard is directed at the prevention of SSC of equipment (includingpressure vessels, heat exchangers, piping, valve bodies, and pump and compressor cases) and componentsused in the refining industry. Prevention of SSC in carbon steel categorized under P-No. 1 in Section IX of theASME Boiler and Pressure Vessel Code (BPVC) is addressed by requiring compliance with NACE SP0472.This International Standard applies to all components of equipment exposed to sour refineryenvironments (see Clause 6) where failure by SSC would (1) compromise the integrity of the pressurecontainmentsystem, (2) prevent the basic function of the equipment, and/or (3) prevent the equipmentfrom being restored to an operating condition while continuing to contain pressure.
