石油和天然气工业，包括低碳能源 — 海上平台和陆上工厂的管道系统 — 第 2 部分：材料

[中文适用范围]： 本文件提供了一组针对上游石油和天然气管道系统中最常用材料的通用补充要求。本文件适用于海上和陆上生产设施、加工和天然气液化厂。本文件中涵盖的材料旨在用于以下管道系统服务： — 按照 ASME B31.3，D 类、M 类、常压和高压； — ISO 15156 系列定义的酸性环境。 注：就本文件而言，ANSI/NACE MR0175 等同于 ISO 15156 系列，ANSI/NACE MR0103 等同于 ISO 17945。本文件不提供材料选择的指南。选择适合特定服务的材料（包括任何必要的附加材料要求）仍是最终用户的责任。本文件不涵盖与以下方面相关的要求： — ISO 17945 中包含的腐蚀性石油精炼环境中的硫化物应力开裂（SSC）； — 符合 ASME B31.3 或 ISO 14692 系列的非金属管道系统； — 分类规则涵盖的海洋管道系统，例如压载管道系统； — 海底生产系统； — 井下设备； — 按照公认的管道设计规范设计的运输管道系统，包括流水线。 附录 A 和附录 B 包括与管道和阀门部件的制造、检验和采购相关的通用要求，分别提供材料数据表和元件数据表。这些材料和元件数据表可用于管道系统以外的应用，例如压力容器和泵，具体取决于最终用户的评估以及与相关设备所选设计规范的一致性。 本文件无意限制在参考材料标准内使用替代材料或等级。 如果认为使用替代材料/等级是合适的，最终用户有责任指定满足设计规范或规范所需的任何其他要求。 1 [外文原描述]： This document provides a set of common supplementary requirements for the most frequently used materials in upstream oil and gas piping systems. This document is applicable to offshore and onshore production facilities, processing and gas liquefaction plants. The materials covered in this document are intended to be used in the following piping systems services: — category D, category M, normal and high pressure, according to ASME B31.3; — sour environments as defined in the ISO 15156 series. NOTE For the purposes of this document, ANSI/NACE MR0175 is equivalent to the ISO 15156 series, and ANSI/NACE MR0103 is equivalent to ISO 17945. This document does not provide guidelines for material selection. The selection of suitable materials for a specific service including any necessary additional material requirements remains the responsibility of the end user. This document does not cover requirements related to: — sulfide stress cracking (SSC) in corrosive petroleum refining environments included in ISO 17945; — non-metallic piping systems according to ASME B31.3 or the ISO 14692 series; — marine piping systems, e.g. ballasting piping system, covered by classification rules; — subsea production systems; — downhole equipment; — transportation pipeline systems, including flowlines, designed in accordance with a recognized pipeline design code. Common requirements related to manufacture, inspection and procurement of piping and valve parts are included in Annex A and Annex B, providing material datasheets and element datasheets, respectively. These material and element datasheets can be applied for applications other than piping systems, e.g. pressure vessels and pumps based upon assessment of the end user and conformance with the selected design code for the relevant equipment. This document is not intended to limit the use of alternative materials or grades within a referenced material standard. Where the use of alternative materials/grades are considered appropriate, the end user is responsible for specifying any additional requirements necessary to meet the design code or specification.
