镀锌管的分类你知道有哪些吗?

来源:http://www.jnlhjscl.com/ 日期:2020-06-04 发布人:adminlehao

  镀锌管,是一种常用的钢材设备,其优异的功用备受广大客户的喜爱。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,运用寿命长等利益。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许多。济南镀锌管来给您介绍一下它的分类吧。您可以来参考学习一下!

  Galvanized pipe is a common steel equipment, its excellent function is loved by customers. Galvanized steel pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing 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 hot-dip galvanized pipe. Jinan galvanized pipe to introduce its classification to you. You can learn by reference!

  Jinan galvanized pipe
  1、热镀锌钢管
  1. Hot dip galvanized steel pipe
  钢管基体与熔融的镀液发作杂乱的物理、化学反响,构成耐腐蚀的结构严密的锌一铁合金层。合金层与纯锌层、钢管基体融为一体。故其耐腐蚀能力强。
  The matrix of steel pipe and molten plating bath have disordered physical and chemical reactions, forming a zinc iron alloy layer with tight corrosion resistance structure. The alloy layer is integrated with pure zinc layer and steel pipe matrix. Therefore, it has strong corrosion resistance.
  2、冷镀锌钢管
  2. Cold galvanized steel pipe
  锌层是电镀层,锌层与钢管基体独立分层。锌层较薄,锌层简略附着在钢管基体上,简略坠落。故其耐腐蚀功用差。在新建住所中,阻止运用冷镀锌钢管作为给水管。
  Zinc layer is electroplated layer, and the zinc layer is separated from the steel pipe matrix. The zinc layer is relatively thin, and the zinc layer is slightly attached to the steel pipe substrate and slightly falls. Therefore, its corrosion-resistant function is poor. In the newly-built residence, it is forbidden to use the cold galvanized steel pipe as the water supply pipe.
  3、热镀锌管
  3. Hot dip galvanized pipe
  是使熔融金属与铁基体反响而发作合金层,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,经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,运用寿命长等利益。冷镀锌就是电镀锌,镀锌量很少,只需10-50g/m2,其本身的耐腐蚀性比热镀锌管相差许多。正规的镀锌管生产厂家,为了保证质量,大多不选用电镀锌(冷镀)。只需那些规划小、设备陈旧的小企业选用电镀锌,当然他们的价格也相对廉价一些。往后禁绝用冷镀锌管作水、煤气管。
  Is to make the molten metal and the iron matrix react and attack the alloy layer, so that the matrix and the coating are combined. Hot dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, the steel pipe shall be cleaned by ammonium chloride or zinc chloride aqueous solution or the mixture of ammonium chloride and zinc chloride aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Cold galvanizing is galvanizing, the amount of galvanizing is very small, only 10-50g / m2, its corrosion resistance is much different from that of hot galvanizing pipe. Regular galvanized pipe manufacturers, in order to ensure the quality, most do not choose galvanizing (cold plating). Only those small enterprises with small planning and old equipment need to choose galvanizing, of course, their prices are relatively low. In the future, it is forbidden to use cold galvanized pipes as water and gas pipes.
