锌管运用
Application of zinc pipe
为进步钢管的耐腐蚀性能,对一般钢管进行镀锌。镀锌钢管分热镀锌和电镀锌两种,热镀锌镀锌层厚,电镀锌成本低,外表不是很润滑。吹氧焊管:用作炼钢吹氧用管,一般用小口径的焊接钢管,标准由3/8-2寸八种。用08、10、15、20或者195-Q235的钢带制作成的,为了防腐蚀,有的要进行渗铝处理。
In order to improve the corrosion resistance of steel pipes, galvanizing is applied to common steel pipes. Galvanized steel pipes are divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing has thick galvanizing layer, low galvanizing cost and poor lubrication in appearance. Oxygen-blowing welded pipe: used as oxygen-blowing pipe for steelmaking, usually small-caliber welded pipe, standard from 3/8-2 inch eight kinds. Made of 08, 10, 15, 20 or 195-Q235 steel strips, in order to prevent corrosion, some of them need to be aluminized.
老房子大部分用的都是镀锌管,现在煤气、暖气用的那种铁管也是镀锌管,镀锌管作为水管,运用几年后,管内产生大量锈垢,流出的黄水不只污染洁具,而且夹杂着不润滑内壁滋生的细菌,锈蚀形成水中重金属含量过高,严重危害人体的健康。六七十年代,国际上发达国家开端开发新式管材,并连续禁用镀锌管。中国建设部等四部委也发文明确从二000年起禁用镀锌管,目前新建小区的冷水管现已很少运用镀锌管了,有些小区的热水管运用的是镀锌管。
Most of the old houses used galvanized pipes. Now the kind of iron pipes used for gas and heating are galvanized pipes. Galvanized pipes are used as water pipes. After several years of application, a large number of rust scales are produced in the pipes. The yellow water not only pollutes the sanitary ware, but also contains bacteria that grow on the non-lubricating inner wall. The heavy metal content in the rust water is too high, which seriously endangers human health. In the 1960s and 1970s, developed countries began to develop new pipes and continuously banned galvanized pipes. Four ministries, such as the Ministry of Construction of China, have banned galvanized pipes since 2000. At present, galvanized pipes are seldom used in cold pipes of newly built residential areas, and galvanized pipes are used in hot pipes of some residential areas.

Classification of galvanized tubes
镀锌钢管分冷镀管、热镀管,前者已被禁用,后者还被国家发起暂时能用.
Galvanized steel pipes are divided into cold-plated pipes and hot-plated pipes. The former has been banned, while the latter has been initiated by the state for temporary use.
热镀锌管
Hot dip galvanized pipe
是使熔融金属与铁基体反响而产生合金层,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,为了去除钢管外表的氧化铁,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,运用寿命长等优点。
It is to make molten metal and iron matrix react to produce alloy layer, so that the matrix and coating are combined. Hot-dip galvanizing first pickles steel pipes. In order to remove iron oxide from the surface of steel pipes, after pickling, the steel pipes are cleaned by ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to hot-dip galvanizing tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
冷镀锌管
Cold galvanized pipe
冷镀锌就是电镀锌,镀锌量很少,只要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,大多不采用电镀锌(冷镀)。只要那些规模小、设备陈旧的小企业采用电镀锌,当然他们的价格也相对廉价一些。目前建设部已正式下文,筛选技术落后的冷镀锌管,今后不准用冷镀锌管作水、煤气管。
Cold galvanizing is galvanizing. The amount of galvanizing is very small. As long as 10-50g/m2, the corrosion resistance of cold galvanizing is much different from that of hot galvanizing tubes. Normal galvanized pipe manufacturers, in order to ensure quality, mostly do not use galvanized (cold plating). As long as those small enterprises with obsolete equipment adopt galvanizing, of course, their prices are relatively cheap. At present, the Ministry of Construction has officially selected the cold galvanized pipes with backward technology. In the future, the cold galvanized pipes are not allowed to be used as water and gas pipes.
热镀锌钢管
Hot-dip galvanized steel pipe
钢管基体与熔融的镀液发生杂乱的物理、化学反响,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 physical and chemical reactions between the steel tube matrix and the molten plating solution are disorderly, forming a zinc-iron alloy layer with a close corrosion resistance structure. The alloy layer is integrated with pure zinc layer and steel tube matrix. Therefore, it has strong corrosion resistance.
