包括低碳能源的石油和天然气工业 碳钢过程容器的内涂层 第2部分：涂层系统选择的要求和指南

[中文适用范围]： 本文件规定了在工艺容器中用于承压服务的内涂层（通常称为衬里）选择的标准和最低要求。文件内容包括：— 影响涂层选择的关键因素；— 用于评估涂层支持性测试证据时可作为参考的测试液体的一般组成；— 在选择合适的涂层时用作性能证据的主要测试方法；— 用于评估涂层时与潜在最终用途相关的支持性证据。本文件涵盖的涂层类型一般是市场上可获得的，其性能已被记录和确认。此外，还包括需评估和合格使用的其他材料。本文件适用于新建阶段涂覆的工艺容器。只有在涂层直接涂覆于基材上时，方可应用本文件。本文件不涵盖与金属涂层或焊接堆焊材料有关的要求。 [外文原描述]： This document specifies the criteria and minimum requirements for selecting internal coatings (often referred to as linings) for pressurized service within process vessels. The document provides the following: — key factors influencing coating selection; — generic composition of test liquids which can be used as references when evaluating supporting testing evidence for coatings; — principal test methods to be used as evidence of performance when selecting suitable coatings; — supporting evidence to be used in evaluating coatings that is relevant to the potential end use. This document covers types of coatings that are generally available, with properties that are known and documented. It also covers other materials to be evaluated and qualified for use . This document is applicable to process vessels coated at the new construction phase. It can be applied only where the coating is applied directly to the substrate. This document does not cover requirements related to metallic coatings nor weld overlay materials.
