  • Description
镀锌管,又称镀锌钢管,分热镀锌和电镀锌两种,热镀锌镀锌层厚,具有镀层均匀,附着力强,使用寿命长等优点。电镀锌成本低,表面不是很光滑,其本身的耐腐蚀性比热镀锌管差很多。 分类 镀锌钢管分冷镀锌钢管、热镀锌钢管,前者已被禁用,后者还被国家提倡暂时能用。 热镀锌钢管钢管基体与熔融的镀液发生复杂的物理、化学反应,形成耐腐蚀的结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。 冷镀锌钢管锌层是电镀层,锌层与钢管基体独立分层。锌层较薄,锌层简

分类

镀锌钢管分冷镀锌钢管、热镀锌钢管,前者已被禁用,后者还被国家提倡暂时能用。

热镀锌钢管钢管基体与熔融的镀液发生复杂的物理、化学反应,形成耐腐蚀的结构紧密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。

冷镀锌钢管锌层是电镀层,锌层与钢管基体独立分层。锌层较薄,锌层简单附着在钢管基体上,容易脱落。故其耐腐蚀性能差。在新建住宅中,禁止使用冷镀锌钢管作为给水管。

用途

消防工程:现在的消防供水管,基本上都是采用的镀锌管,在镀锌管的外层再涂上一层油漆,这样就是大家可以看到红色的消防管,其实只是经过镀锌管加工形成的。

钢结构,焊接工程:现在外面很多搭棚厂房,以前搭厂房都是用焊接的钢管,但是焊接的钢管容易生锈,为了防止生锈还要涂上一层油漆,为了解决这个问题,现在很多新的钢结构的工程都直接采用镀锌管,这样可以省工时,又可以用的时间更长久。
