标准范围

ISO 21809-2:2007规定了ISO 13623中定义的石油和天然气行业管道运输系统用裸钢管防腐用单层熔结环氧树脂（FBE）涂层工厂应用材料的鉴定、应用、测试和处理要求。ISO 21809-2:2007不包括玻璃化转变温度高于120°C的高温涂层或用于三层或多层聚乙烯或聚丙烯涂层的FBE底漆涂层。根据ISO 21809-2:2007进行涂层的管道被认为适合通过阴极保护进行额外保护。

ISO 21809-2:2007 specifies the requirements for qualification, application, testing and handling of materials for plant application of single-layer fusion-bonded epoxy (FBE) coatings applied externally for the corrosion protection of bare steel pipe for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623.High-temperature coatings with a glass transition of above 120 °C or FBE primer coatings for three- or multi-layer polyethylene or polypropylene coatings are not covered by ISO 21809-2:2007.Pipes coated in accordance with ISO 21809-2:2007 are considered suitable for additional protection by means of cathodic protection.
