热镀锌管是使熔融金属与铁基体反应而产生合金层,从而使基体和镀层二者相结合。热镀锌是先将钢管进行酸洗,为了去除钢管表面的氧化铁,酸洗后,通过氯化铵或氯化锌水溶液或氯化铵和氯化锌混合水溶液槽中进行清洗,然后送入热浸镀槽中。

The hot-dip galvanizing tube is to make the molten metal react with the iron matrix to produce the alloy layer, so that the matrix and the two layers of the coating are combined. Hot dip galvanizing is to pickle steel pipes first, then remove iron oxides on the surface of steel pipes, then pickle them, then clean them through ammonium chloride or zinc chloride water solution or ammonium chloride and zinc chloride mixed water solution tank, then send them into hot dip bath.

冷镀锌就是电镀锌,镀锌量很少,只有10-50g/m2,其本身的耐腐蚀性比热镀锌管相差很多。正规的镀锌管生产厂家,为了保证质量,大多不采用电镀锌。只有规模小、设备陈旧的小企业采用电镀锌,当然他们的价格也相对便宜一些。

Cold galvanizing is electrogalvanizing with little amount of galvanizing, only 10 - 50g/m2, and its corrosion resistance is much different from that of hot dip galvanized pipe. Regular galvanized pipe manufacturers, in order to ensure quality, most of the use of galvanizing. Only small businesses with old equipment are galvanized, and of course their prices are relatively cheap.

一般现在用的镀锌钢管都是热镀锌的,而电气上用的线槽等用的是冷镀锌,颜色有一定的区别,冷镀只在外管壁镀锌,热镀内外都镀,镀锌焊管是在焊接钢管的基础上再热镀锌,使钢管内外壁同时有一层锌层附着,镀锌管一般用于低压流体的输送。

Now the general galvanized steel pipe is used in hot galvanizing, and electrical use trough etc. with the cold galvanized, color has certain difference, only in the cold plating tube wall galvanized, hot dip galvanized welded pipe inside and outside plating is based on reheat welded steel pipe galvanized, the outer and inner walls with steel tube when there is a layer of zinc layer, galvanized pipe commonly used for conveying low pressure fluid.
