美国腐蚀工程师学会于1969年首次制定了《浸埋金属管道系统的外部腐蚀控制》标准(NACE Standard RP—01—69),到1983年进行了第三次修定。本标准较系统地总结了已往的实践经验,比较详细地阐明了有效的防护技术及其实施方法。其中主要有浸埋金属管道系统的结构设计原则,涂层防护方法—包括防腐蚀涂层的选择、涂装技术、检验、评定等,阴极保护技术—包括阴极保护的准则、保护系统的设计、施工、维护与管理,杂散电流影响及其防治方法等。这些经验也适用于浸埋的金属结构物的防腐蚀。所涉及的主要金属是钢、铸铁、球墨铸铁、铜、铅等。下面就其主要防护措施作一
The American Society of Corrosion Engineers first developed the NACE Standard RP-01-69 in 1969 and the third revision in 1983. This standard systematically summarizes the past practical experience, a more detailed explanation of the effective protection technology and its implementation. Among them are the principle of structural design of immersed metal piping system, the methods of coating protection - including the selection of anti-corrosion coating, coating technology, inspection and assessment, cathodic protection technology - including cathodic protection guidelines, protection system design, Construction, maintenance and management, stray current and its prevention and treatment methods. These experiences also apply to the corrosion protection of immersed metal structures. The main metals involved are steel, cast iron, ductile iron, copper, lead and the like. Here’s one of its main protective measures
