镀锌管有哪几种分类?

一、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。热镀锌具有镀层均匀,附着力强,使用寿命长等优点。北方大部分工艺采用镀锌带直接卷管补锌工艺。

First, hot galvanized pipe is to make molten metal react with iron substrate to produce alloy layer, so that the substrate and the two layers of coating are combined. The hot dip galvanizing is first to wash the steel tube, in order to remove the iron oxide on the surface of the steel tube. After pickling, it is cleaned by the solution of ammonium chloride or zinc chloride or ammonium chloride and zinc chloride in the mixed solution tank, and then sent into the hot dip bath. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. In the north, zinc plating process is used in most of the processes.

二、冷镀锌管,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。只有那些规模小、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。今后不准用冷镀锌管作水、煤气管。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。

Two, cold galvanized pipe, cold galvanizing is galvanized, zinc content is very small, only 10-50g/m2, its own corrosion resistance than hot galvanized tube difference. Regular galvanized pipe manufacturers, in order to ensure quality, most do not use galvanized. Only those small and outdated small businesses use zinc plating, of course, their prices are relatively cheaper. In the future, cold galvanized pipes are not allowed to be used as water and gas pipes. The zinc layer is an electroplating layer, and the zinc layer is separately separated from the steel tube substrate. The zinc layer is thin, and the zinc layer is simply attached to the steel tube substrate, so it is easy to fall off. Therefore, its corrosion resistance is poor. In new buildings, cold galvanized steel pipes are not allowed to be used as water pipes.
