无锡镀锌方管热度与冷镀的区别：镀锌方管是一种具以热轧或冷轧镀锌带钢或镀锌卷板为坯料经冷弯曲加工成型后再经高频焊接制成的方形截面形状尺寸的空心方形的截面型钢钢管；或将事先做好的冷弯空心型钢管再经热浸镀锌加工而成的镀锌方矩管。
The difference between hot and cold galvanized square pipes in Wuxi is that the galvanized square pipes are hollow square section steel pipes with square section shape and dimension made by cold bending and forming with hot-rolled or cold-rolled galvanized strip or galvanized coil sheet and high frequency welding, or galvanized square pipes made by hot dipping and galvanizing. 镀锌方管的分类
Classification of galvanized square tubes
无锡镀锌方管从生产工艺上是分为热镀锌方管和冷镀锌方管的。正是由于这两种镀锌方管的加不相同也就造就了它们很多不同的物理和化学性质。总的来说它们在强度、韧性和机械性能方面都有很多的区别。
Wuxi galvanized square pipe is divided into hot galvanized square pipe and cold galvanized square pipe in terms of production technology. It is precisely because of the different addition of these two galvanized square tubes that they have many different physical and chemical properties. Generally speaking, they differ in strength, toughness and mechanical properties.
热镀锌方管
Hot-dip galvanized square tube
热镀锌方管：是在使用钢板或者是钢带卷曲成型后焊接制成的方管，并在这种方管的基础上将方管置于热镀锌池中经过一系列化学反响有形成的一种方管。热镀锌方管的生产工艺较为简答，但是生产效率是很高的，品种规格也多，但这种方管所需要的设备和资金很少，和适合小型镀锌方管厂家的生产。但是从强度上来说这种钢管的强度是远远低于无缝方管的。
Hot-dip galvanized square pipe: a square pipe made by welding steel plate or steel strip after coiling and forming. On the basis of this square pipe, square pipe is placed in hot-dip galvanized pool and formed through a series of chemical reactions. Hot-dip galvanized square pipe production process is relatively simple, but the production efficiency is very high, variety specifications are also many, but this kind of square pipe requires little equipment and funds, and suitable for small-scale galvanized square pipe manufacturers. But in terms of strength, the strength of this kind of steel pipe is far lower than that of seamless square pipe.
冷镀锌方管
Cold Galvanized Square Pipe
而冷镀锌方管是在所用的方管上利用冷镀锌的原理来使方管具有防腐蚀的性能。与热镀锌不同冷镀锌涂料主要通过电化学原理来进行防腐，因此必须保证锌粉与钢材的充分接触，产生电极电位差，所以钢材表面处理很重要。
The cold galvanized square pipe is used to make the square pipe have anti-corrosion performance by using the principle of cold galvanizing. Different from hot-dip galvanizing, cold-dip galvanizing coatings are mainly anti-corrosion based on electrochemical principle. Therefore, it is necessary to ensure full contact between zinc powder and steel to produce electrode potential difference, so surface treatment of steel is very important.
冷、热镀锌方管的区别
Differentiation between cold galvanized square tubes and hot galvanized square tubes
镀锌方管有热镀锌方管和冷镀锌方管两大类。热镀锌方管有湿法、干法、铅锌法、氧化还原法等。不同热镀锌方法的主要区别在钢管酸浸清洗后，用什么方法活化管体表面提高镀锌质量。现生产中主要采用干法和氧化还原法，其特点见表。
Galvanized square tubes can be divided into hot galvanized square tubes and cold galvanized square tubes. Hot-dip galvanized square pipe has wet method, dry method, lead-zinc method, oxidation-reduction method and so on. The main difference between different hot-dip galvanizing methods is how to activate the surface of pipe body to improve galvanizing quality after acid leaching cleaning. Dry process and redox process are mainly used in production, and their characteristics are shown in table.
冷镀锌的锌层表面十分光滑致密、组织均匀;具有良好的力学性能和抗腐蚀能力;锌耗比热镀锌低60%～75%。电镀锌在技术上有一定的复杂性，但对单面镀层，内外表面镀层厚度不同的双面镀层，以及薄壁管镀锌等皆须采用此法。
The surface of cold galvanized zinc coating is smooth, compact and uniform in structure. It has good mechanical properties and corrosion resistance. The consumption of zinc is 60%-75% lower than that of hot galvanized zinc. Zinc plating is technically complicated, but it is necessary to use this method for single-sided coating, double-sided coating with different thickness of inner and outer surface coating, and thin-walled tube galvanizing.
