本技术委员会报告描述了当前的行业 实践并提供最常用的 螺纹紧固件保护用通用涂层系统 与结构钢、管道和设备一起使用。这个 涂层系统在两层之间提供保护屏障 基底金属和环境，以尽量减少 腐蚀本报告中提供的信息 处理钢材质量、预处理工艺、涂层 应用、质量保证/质量控制和测试 用于评估耐腐蚀性的比较。这 报告并未反映NACE在这些问题上的立场 而是总结了现有的技术和 各种制造商、涂敷商和用户的实践。

This technical committee report describes current industry practices and gives information on the most commonly used generic coating systems for protection of threaded fasteners used with structural steel, piping, and equipment. The coating system provides a protective barrier between the base metal and the environment to minimize the effect of corrosion. The information presented in this report addresses steel quality, pretreatment processes, coating application, quality assurance/quality control, and test comparisons for evaluating corrosion resistance. This report does not reflect the NACE position on these practices, but rather summarizes existing technology and practices of various manufacturers, applicators, and users.
