鍍鋅方管是一種在方管的基礎上面，進行了合適的鍍鋅處理的管材，因此在應用范圍方面有了比較好的提高，可以使用在機械制造和鋼結構工程等領域，具有比較好的使用效果。那么您知道該產品的工藝分類和具體的區別嗎？就先讓濟南鍍鋅方管的小編給您來簡單講解一下吧。

Galvanized square pipe is a kind of pipe with proper galvanizing treatment on the basis of square pipe, so it has a better improvement in the scope of application, and can be used in the fields of mechanical manufacturing and steel structure engineering, with better use effect. Do you know the process classification and specific difference of this product? Let's first let Jinan galvanized square tube's editor give you a brief explanation.

鍍鋅方管從生產工藝上是分為熱鍍鋅方管和冷鍍鋅方管的。正是由于這兩種鍍鋅方管的加工不相同也就造就了它們很多不同的物理和化學性質。總的來說它們在強度、韌性和機械性能方面有很多的區別。

Galvanized square tube is divided into hot-dip galvanized square tube and cold-dip galvanized square tube from the production process. It is because of the different processing of these two kinds of galvanized square tubes that they have many different physical and chemical properties. Generally speaking, they have many differences in strength, toughness and mechanical properties.

1.熱鍍鋅方管：

1. Hot dip galvanized square pipe:

是在使用鋼板或者是鋼帶卷曲成型后焊接制成的方管，并在這種方管的基礎上將方管置于熱鍍鋅池中經過一系列化學反應后又形成的一種方管。熱鍍鋅方管的生產工藝較為簡單，且生產效率是高的，品種規格也多，這種方管所需要的設備和資金少，適合小型鍍鋅方管廠家的生產。但是從強度上來說這種鋼管的強度是低于無縫方管的。

It is a kind of square tube which is made by welding after rolling steel plate or steel strip. On the basis of this kind of square tube, the square tube is put in the hot-dip galvanizing bath and formed after a series of chemical reactions. The production process of hot-dip galvanized square tube is relatively simple, and the production efficiency is high, and there are many varieties and specifications. This kind of square tube needs less equipment and capital, which is suitable for the production of small galvanized square tube manufacturers. But in terms of strength, the strength of this kind of steel pipe is lower than that of seamless square pipe.

2.冷鍍鋅方管：

2. Cold galvanized square pipe:

而冷鍍鋅方管是在所用的方管上利用冷鍍鋅的原理來使方管具有防腐蝕的性能。與熱鍍鋅不同冷鍍鋅涂料主要通過電化學原理來進行防腐，因此須使得鋅粉與鋼材的接觸，產生電極電位差，所以鋼材表面處理很重要。

The cold galvanizing square tube is to use the principle of cold galvanizing to make the square tube have anti-corrosion performance. Different from hot-dip galvanizing, cold-dip galvanizing coating mainly uses electrochemical principle for anti-corrosion, so it is necessary to make the contact between zinc powder and steel, resulting in electrode potential difference, so steel surface treatment is very important.

3.冷熱鍍鋅區別：

3. Difference between cold and hot galvanizing:

鍍鋅方管有熱鍍鋅方管和電鍍鋅方管兩類。熱鍍鋅方管有濕法、干法、鉛鋅法、氧化還原法等。不同熱鍍鋅方法的主要區別在鋼管酸浸清洗后，用什么方法活化管體表面提高鍍鋅質量。現生產中主要采用干法和氧化還原法。電鍍鋅的鋅層表面光滑致密、組織均勻;具有良好的力學性能和抗腐蝕能力;鋅耗比熱鍍鋅低60%～75%。電鍍鋅在技術上有較多的復雜性，但對單面鍍層，內外表面鍍層厚度不同的雙面鍍層，以及薄壁管鍍鋅等須采用此法。

There are two kinds of galvanized square tubes: hot-dip galvanized square tube and electro galvanized square tube. Hot dip galvanized square tube has wet, dry, lead-zinc, oxidation-reduction method. The main difference of different hot-dip galvanizing methods lies in how to activate the surface of steel tube after acid leaching to improve the quality of galvanizing. At present, dry process and oxidation-reduction process are mainly used in production. The surface of zinc coating is smooth, compact and uniform; It has good mechanical properties and corrosion resistance; Zinc consumption is 60% ～ 75% lower than that of hot dip galvanizing. There are many technical complexities in galvanizing, but this method must be used for single-sided coating, double-sided coating with different thickness of inner and outer surface coating, and thin-walled tube galvanizing.
