DN32不锈钢管道能做防腐和内衬吗?是不是管径太小了?直径多大的管道适合做防腐和内衬?

估计做不了内衬,直接升级材料吧

都不锈钢了,不是自带防腐?321SS的不锈钢防腐不错,不知道楼主是哪种?

这点你错了,防腐只是针对性的防腐。 不锈钢也有扛不住腐蚀的介质。 这种小口径的内衬防腐,还不如直接升级材料。 针对介质,换相应的抗腐蚀比较强的材料,比如:钛材料,镍材料。

嗯嗯,是的啊!楼主没有说介质,一般情况下,321SS防腐能力已相当好了!

分清腐蚀来源才有针对性的解决! 以此话题,DN32管如果腐蚀来源于氢,那么就可以用“自蔓延”处理,如果防止液相腐蚀,则可以采用高分子涂料技术。 相对升级材料,一般来说还是合算的。
