本标准描述了安装在地上、地下或水下的水处理设备中使用的钢管、连接件、配件和特殊截面（物品）的内部和外部尼龙-11基聚酰胺涂层系统。聚酰胺涂层系统是热塑性的，通常用于车间或生产设施。本标准的目的是建立和描述用于水处理的钢制品的聚酰胺系统的应用和使用的最低要求，以最大限度地提高长期性能？尤其是长- 术语腐蚀防护。

This standard describes Nylon-11-based polyamide coating systems for interior and exterior of steel pipe, connections, fittings, and special sections (articles) that are used in water-handling equipment that is installed aboveground, belowground, or underwater. Polyamide coating systems are thermoplastic and are ordinarily applied in a shop or manufacturing facility.The purpose of this standard is to establish and describe the minimum requirements for the application and use of polyamide systems for steel articles employed in water handling to maximize long-term performance?in particular, long-term corrosion protection.
