本文件为上游石油和天然气管道系统中最常用的材料提供了一套通用的补充要求。 本文件适用于海上和陆上生产设施、加工和气体液化工厂。本文件中涵盖的材料旨在用于以下管道系统服务: —？D类、M类、常压和高压，根据ASME B31.3； —？ISO 15156系列中定义的酸性环境。 笔记？就本文件而言，ANSI/NACE MR0175相当于ISO 15156系列，ANSI/NACE MR0103相当于ISO 17945。 本文件不提供材料选择指南。为特定服务选择合适的材料，包括任何必要的额外材料要求，仍然是最终用户的责任。本文件不涵盖以下方面的要求: —？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； —？根据公认的管道设计规范设计的运输管道系统，包括出油管。 与管道和阀门部件的制造、检验和采购有关的共同要求见附件？A和附件？B、分别提供材料数据表和元素数据表。这些材料和元件数据表可应用于管道系统以外的应用，例如基于对最终用户的评估以及与相关设备所选设计规范的一致性的压力容器和泵。本文件无意限制参考材料标准内替代材料或等级的使用。如果认为使用替代材料/等级是合适的，最终用户负责指定满足设计规范或规范所需的任何附加要求。

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.
