DIN EN ISO17945:2015-08EN ISO 17945:2015 (E)4IntroductionThe term “wet H2S cracking”, as used in
36、 the refining industry, covers a range of damage mechanisms that can occur because of the effects of hydrogen charging in wet H2S refinery or gas plant process environments. One of the types of material damage that can occur as a result of hydrogen charging is sulfide stress cracking (SSC) of hard w
37、eldments and microstructures, which is addressed by this International Standard. Other types of material damage include hydrogen blistering, hydrogen-induced cracking (HIC), and stress-oriented hydrogen-induced cracking (SOHIC), which are not addressed by this International Standard.Historically, ma
38、ny end users, industry organizations (e.g. API), and manufacturers that have specified and supplied equipment and products such as rotating equipment and valves to the refining industry have used NACE MR0175/ISO 15156 to establish materials requirements to prevent SSC. However, it has always been re
39、cognized that refining environments are outside the scope of NACE MR0175/ISO 15156, which was developed specifically for the oil and gas production industry. In 2003, the first edition of NACE MR0103 was published as a refinery-specific sour service metallic materials standard. This International St
40、andard is based on the good experience gained with NACE MR0175/ISO 15156, but tailored to refinery environments and applications. Other references for this International Standard are NACE SP0296, NACE Publication 8X194, NACE Publication 8X294, and the refining experience of the task group members wh
41、o developed NACE MR0103.The materials, heat treatments, and material property requirements set forth in NACE MR0103 are based on extensive experience in the oil and gas production industry, as documented in NACE MR0175/ISO 15156, and were deemed relevant to the refining industry by the task group.Th
42、is International Standard was developed on the basis of NACE MR0103.DIN EN ISO17945:2015-08EN ISO 17945:2015 (E)51 ScopeThis International Standard establishes material requirements for resistance to SSC in sour petroleum refining and related processing environments containing H2S either as a gas or
43、 dissolved in an aqueous (liquid water) phase with or without the presence of hydrocarbon. This International 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 are outside the
44、 scope of this International Standard. It is intended to be used by refiners, equipment manufacturers, engineering contractors, and construction contractors.Specifically, this International Standard is directed at the prevention of SSC of equipment (including pressure vessels, heat exchangers, pipin
45、g, valve bodies, and pump and compressor cases) and components used in the refining industry. Prevention of SSC in carbon steel 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.This International Standard
46、 applies to all components of equipment exposed to sour refinery environments (see Clause 6) where failure by SSC would (1) compromise the integrity of the pressure-containment system, (2) prevent the basic function of the equipment, and/or (3) prevent the equipment from being restored to an operati
47、ng condition while continuing to contain pressure.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
