请教关于深海项目的防腐标准

请教各位侠客:

             哪位对深海钢结构的防腐标准比较清楚?有哪些?
            个人认为应该与常规项目执行标准一样吧?有哪些特殊的?

         深海钢结构啊,你想知道什么样的,海底撬块,设备还是海底储罐、浮筒类的结构的防腐要求呢?

海底撬块的,水下管汇,海底储罐的都行啊。我觉得标准应该还差不多。你有相关资料么?分享一下,十分感谢啊!

            打砂喷漆的基本要求都是一样的,就是深海钢结构,对打砂的表面处理和盐分含量要求较高,一般喷砂到Sa3,盐分要低于20mg/m2。使用能兼容阴极保护的油漆系统,在常规检验项的基础上,需要增加漏涂点的检测。

不过海底管道的涂装要单独考虑,海底金属管道一般采用涂敷层和阴极保护结合的方式来保护,而聚乙烯防腐技术是目前国内外海底管道外防腐的主要技术体系之一。
