镀锌钢管有什么特点?

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。

Galvanized pipe, also known as galvanized steel pipe, is divided into two types, hot galvanizing and galvanizing. Hot dip galvanized zinc coating is thick, which has the advantages of uniform coating, strong adhesion and long service life. The cost of galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of the hot galvanized pipe.

镀锌钢管耐腐蚀,而煤气中含有二氧化硫等腐蚀性气体。济南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。

Galvanized steel pipe corrosion resistance, and gas containing sulfur dioxide and other corrosive gases. The Ji'nan galvanized pipe 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.

济南镀锌管热镀锌具有镀层均匀,附着力强,使用寿命长等优点。热镀锌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。

The hot-dip galvanizing of Ji'nan galvanized pipe has the advantages of uniform coating, strong adhesion, long service life and so on. The complex physical and chemical reaction of the hot dipped galvanized steel tube matrix and the molten bath formed a corrosion resistant and tightly structured zinc - iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
