石油 石化和天然气工业.绝缘保护涂层系统的鉴定试验和验收标准（ISO 19277-2018）

[中文适用范围]： 本文件描述了炼油厂和其他相关行业和环境中的各种绝缘下腐蚀 (CUI) 环境，并建立了 CUI 环境类别，包括仅适用于顶部和地面服务的从 −45 °C 到 204 °C 的工作温度范围。本文件规定了用于评估每种给定环境中用于预防 CUI 的涂层的既定和其他测试方法。本文件还提供了每种 CUI 环境的验收标准。注意：测试结果和验收标准可被视为选择合适涂层系统的辅助手段。对于低于 −45 °C 的服务或峰值温度，可以加入可选的低温测试，对于超过 204 °C 的测试，相关方可以商定验收标准。可以采取额外或其他测试和验收措施，但需要相关方之间的特别协议。本文件涵盖喷涂在新碳和奥氏体不锈钢上用于 CUI 服务的涂层。本文件不涵盖牺牲涂层（如无机锌）的测试，因为这些涂层在潮湿环境中会很快消耗。开发针对可连续湿式使用牺牲涂层的加速腐蚀测试超出了本文件的讨论范围。干膜厚度大于 250 µm 的“非穿透孔隙”热喷涂铝涂层可根据本文件进行测试和鉴定。本文件不涵盖用于防止 CUI 的胶带和片材应用产品。本文件不涉及涂层降解的其他方面，例如由磨损、侵蚀、紫外线降解或在特定环境和施工方法下可能存在的其他方法引起的涂层降解。 [外文原描述]： This document describes various corrosion under insulation (CUI) environments in refineries and other related industries and environments, and establishes CUI environmental categories including operating temperature ranges from −45 °C to 204 °C for topside and aboveground service only. This document specifies both established and other test methods for the assessment of coatings used for prevention of CUI for each given environment. This document also provides acceptance criteria for each CUI environment. NOTE The test results and acceptance criteria can be considered an aid in the selection of suitable coating systems. For service or peak temperatures below −45 °C an optional cryogenic test can be incorporated and for over 204 °C testing acceptance criteria can be agreed between interested parties. Additional or other test and acceptance measures are possible, but require particular agreement between the interested parties. This document covers spray-applied coatings applied on new carbon and austenitic stainless steel for use in CUI service. This document does not cover testing of sacrificial coatings, such as inorganic zinc, as these coatings can be consumed quickly in wet environments. Developing accelerated corrosion testing for what can be continuous wet service with sacrificial coatings is beyond the scope of this document. "Non-through porosity" thermal spray aluminium coatings with greater than 250 µm dry film thickness can be tested and qualified in accordance with this document. This document does not cover tape and sheet applied products for use in preventing CUI. This document does not deal with other aspects of coating degradation, such as those caused by abrasion, erosion, ultraviolet degradation or other methods that can exist given specific environment and construction methods.
