This standard establishes material requirements for resistance to SSC in sour petroleum refining 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 standard does not include and is not intended to include
design specifications. Other forms of wet H2S cracking, environmental cracking, corrosion, and other modes of
failure, although outside the scope of this standard, should be considered in the design and operation of
equipment. Severely corrosive and/or hydrogen charging conditions may lead to failures by mechanisms other
than SSC and should be mitigated by methods that are outside the scope of this standard.
Specifically, this standard is directed at the prevention of SSC of equipment (including pressure vessels,
heat exchangers, piping, valve bodies, and pump and compressor cases) and components used in the refining
industry. Prevention of SSC in carbon steel materials categorized under P-No. 1 in Section IX of the ASME
Boiler and Pressure Vessel Code (BPVC) is addressed by requiring compliance with NACE SP0472.
