27、Introduction The provision of well-established and robust material selection guidelines offers a means of satisfying long-term materials performance that meet the minimum requirements for a broad range of end users in the petroleum, petrochemical and natural gas industries. An additional benefit can

28、 be to enable product suppliers to develop, manufacture and provide off-the-shelf equipment that meets these requirements. Oil and gas production projects benefit from a structured evaluation of materials used for the different fluids being handled. Therefore, the main objective of this Internationa

29、l Standard is to provide general requirements with guidelines for the selection of materials for systems and components, with due consideration to the transported fluids and the external environment. It is the end users responsibility to provide a project document with respect to implementation of t

30、he requirements and guidelines of this International Standard, and to specify the design conditions for material selection. In addition to the end user, the organization responsible for the facility or for the equipment design, or for both, is regarded as responsible for materials selection. This In

31、ternational Standard is developed to provide responsible parties with a structured process to carry out materials selection in a consistent manner as a part of the engineering work, based upon a design basis for a particular installation. This International Standard is intended for use by oil compan

32、ies and engineering contractors. Users of this International Standard are advised that further or differing requirements might be needed for individual applications. This International Standard is not intended to inhibit a vendor from offering, or the purchaser from accepting, alternative equipment

33、or engineering solutions for the individual application. This can be particularly applicable where there is innovative or developing technology. Where an alternative is offered, it is advisable that the vendor identify any variations from this International Standard and provide details. DIN EN ISO 2

34、1457:2010-12 EN ISO 21457:2010 (E) 4 1 Scope This International Standard identifies the corrosion mechanisms and parameters for evaluation when performing selection of materials for pipelines, piping and equipment related to transport and processing of hydrocarbon production, including utility and i

35、njection systems. This includes all equipment from and including the well head, to and including pipelines for stabilized products. This International Standard is not applicable to downhole components. Guidance is given for the following: corrosion evaluations; materials selection for specific appli

36、cations, or systems, or both; performance limitations for specific materials; corrosion control. This International Standard refers to materials that are generally available, with properties that are known and documented. It also allows other materials to be evaluated and qualified for use. This Int

37、ernational Standard does not provide detailed material requirements or guidelines for manufacturing and testing of equipment. Such information can be found in particular product and manufacturing standards. 2 Normative references The following referenced documents are indispensable for the applicati

42、loy of carbon and iron containing up to 2 % mass fraction carbon and up to 1,65 % mass fraction manganese and residual quantities of other elements, except those intentionally added in specific quantities for deoxidation (usually silicon and/or aluminium) NOTE Carbon steels used in the petroleum ind

43、ustry usually contain less than 0,8 % mass fraction carbon. ISO 15156-1:2009, definition 3.3 3.1.3 corrosion-resistant alloy alloy intended to be resistant to general and localized corrosion by oilfield environments that are corrosive to carbon steels NOTE This definition is in accordance with ISO 1

44、5156-1 and is intended to include materials such as stainless steel with minimum 11,5 % (mass fraction) Cr, and nickel, cobalt and titanium base alloys. Other ISO standards can have other definitions. 3.1.4 end user owner or organization that is responsible for operation of an installation/facility

45、3.1.5 free-machining steel steel composition to which elements such as sulfur, selenium or lead have been intentionally added to improve machinability 3.1.6 fugacity non-ideal partial pressure that a component in a mixture exerts in the vapour phase when in equilibrium with the liquid mixture NOTE T

46、he fugacity factor depends on the temperature and the total pressure. 3.1.7 glass-fibre-reinforced plastic composite material made of thermosetting resin and reinforced with glass fibres 3.1.8 hydrogen-induced cracking HIC planar cracking that occurs in carbon and low alloy steels when atomic hydrog

47、en diffuses into the steel and then combines to form molecular hydrogen at trap sites 6 DIN EN ISO 21457:2010-12 EN ISO 21457:2010 (E) NOTE Cracking results from the pressurization of trap sites by hydrogen. No externally applied stress is needed for the formation of hydrogen-induced cracks. Trap si

48、tes capable of causing HIC are commonly found in steels with high impurity levels that have a high density of planar inclusions and/or regions of anomalous microstructure (e.g. banding) produced by segregation of impurity and alloying elements in the steel. This form of hydrogen-induced cracking is

49、not related to welding. ISO 15156-1:2009, definition 3.12 3.1.9 hydrogen stress cracking HSC cracking that results from the presence of hydrogen in a metal and tensile stress (residual and/or applied) NOTE HSC describes cracking in metals that are not sensitive to SSC but which can be embrittled by hydrogen when galvanically coupled, as the cathode, to another metal that is corroding actively as an anode. The term “galvanically induced HSC” has been used for this mechanism of cracking. ISO 15156-1:2009, defi
