AWWA（美国自来水厂协会）C210防腐钢管标准解读：美国自来水厂协会（AWWA）致力于水资源这一全球最重要的资源，为水知识、水资源管理以及明智的公共政策制定标准。AWWA成员提供解决方案，以改善公共卫生、保护环境、增强经济实力，并提升我们的生活质量。本标准描述了供水行业中，在正常施工条件下，用于地下或水下安装的钢制水管、特殊管段、焊接接头、连接件和配件的车间涂装和现场涂装的液态环氧涂料和衬里的材料和应用。本标准未描述的条件。本标准所述的涂层系统不适用于在涂层或内衬系统应用后将进行弯曲处理的管道。涂层和衬里系统。涂层和衬里系统可由以下三种类型中的任意一种组成：（1）由两部分组成的化学固化环氧底漆和一层或多层由不同两部分组成的化学固化环氧面漆；（2）两层或多层由相同两部分组成的化学固化环氧涂层，在这种情况下，第一层应视为底漆；或（3）单层由两部分组成的化学固化环氧涂层。最高温度。美国自来水厂协会（AWWA）的钢管涂层和内衬标准是基于饮用水的最高使用温度制定的。有关使用条件和限制，请咨询环氧树脂制造商。AWWA (American Water Works Association) C210 anti-corrosion steel pipe standard interpretation: The American Water Works Association (AWWA) is committed to water resources, the world's most important resource, and sets standards for water knowledge, water resource management, and wise public policy. AWWA members provide solutions to improve public health, protect the environment, enhance economic strength, and improve our quality of life. This standard describes the materials and applications of liquid epoxy coatings and liners for workshop and on-site painting of steel water pipes, special pipe sections, welded joints, connectors, and fittings used for underground or underwater installation in the water supply industry under normal construction conditions. Conditions not described in this standard. The coating system described in this standard is not applicable to pipelines that will undergo bending treatment after the application of coating or lining systems. Coating and lining system. The coating and lining system can be composed of any one of the following three types: (1) a chemical cured epoxy primer composed of two parts and one or more layers of chemical cured epoxy topcoat composed of different two parts; (2) Two or more layers of chemically cured epoxy coating composed of the same two parts, in which case the first layer should be considered as the primer; Or (3) a single layer of chemically cured epoxy coating composed of two parts. maximum temperature. The steel pipe coating and lining standards of the American Water Works Association (AWWA) are based on the maximum operating temperature of drinking water. For usage conditions and restrictions, please consult the epoxy resin manufacturer.
