What is hot-dip galvanized pipe

Hot dip galvanized pipe is the reaction of molten metal with iron matrix to produce alloy layer, so that the matrix and the coating are combined.


Hot dip galvanizing is to first pickling the steel pipe, in order to remove the iron oxide on the surface of the steel pipe, after pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank.


Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The matrix of hot dip galvanized steel pipe and the molten bath undergo complex physical and chemical reactions to form a tight zinc-iron alloy layer with corrosion resistance.

The alloy layer is integrated with the pure zinc layer and the steel pipe matrix, so its corrosion resistance is strong.

What is galvanized coating

Galvanizing refers to the surface treatment technology of plating a layer of zinc on the surface of metals, alloys or other materials to play the role of aesthetics and rust prevention.  The main method used is hot-dip galvanizing.  


Zinc is soluble in acids and alkali, so it is called an amphoteric metal.  Zinc changes little in dry air.  In moist air, a dense basic zinc carbonate film forms on the surface of zinc.  In the atmosphere containing sulfur dioxide, hydrogen sulfide and Marine atmosphere, zinc corrosion resistance is poor, especially in the high temperature and high humidity atmosphere containing organic acid, zinc coating is easily corroded.  The standard electrode potential of zinc is -0.76V, for the steel substrate, zinc coating belongs to the anodic coating, which is mainly used to prevent the corrosion of steel, and its protective performance is greatly related to the thickness of the coating.  The protection and decoration of zinc coating can be improved significantly after passivation, dyeing or coating with light protector.

The difference between hot dip galvanizing and Pre galvanizing

1, the two functions are not the same 

Hot dip galvanizing has the advantages of uniform coating, strong adhesion, long service life, etc. The hot dip galvanizing steel pipe matrix and the molten bath undergo complex physical and chemical reactions to form a tight zinc-iron alloy layer with corrosion resistance.   pre Galvanized  is a common material coated with zinc on the outside surface, which plays an external anti-corrosion role, and also has a certain aesthetic effect, but mainly anti-corrosion. 

2.   The two concepts are different 

Hot dip galvanizing through the principle of zinc resistance to atmospheric corrosion, to carry out electrochemical protection of steel and other materials, the surface of zinc carbonate protective film can slow down the speed of zinc corrosion, even if it is destroyed, it will form a zinc film. The pre galvanized  refers to the straight out of the galvanized tube, that is, the surface of the black tube is plated with zinc, which only plays the role of basic anti-corrosion and aesthetics.

Advantages of hot dipped galvanized 

The main advantages are: low treatment cost: the cost of hot dip galvanized rust prevention is lower than that of other paint coatings;  Durable: In the suburban environment, the standard hot-dip galvanized rust prevention thickness can be maintained for more than 50 years without repair;  In urban or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair;  Good reliability: the galvanized layer and the steel is a metallurgical combination, becoming a part of the steel surface, so the durability of the coating is more reliable;  The toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use;  Comprehensive protection: Every part of the plating can be plated with zinc, even in the depression, sharp corners and hidden places can be fully protected;  Save time and effort: The galvanizing process is faster than other coating methods and avoids the time required to apply on the site after installation. 

The application range of hot-dip galvanized square tube 

First, the construction field。In construction projects, hot-dip galvanized square pipes are mainly used as an important part of building drainage systems and ventilation pipes, such as: indoor drainage systems, building drainage systems, rainwater pipes, etc. In the steel structure, the hot-dip galvanized square pipe as the joint pipe between the beam and column can play a very good supporting role. In addition, in the fire protection system of buildings, hot-dip galvanized square pipe also plays an important role, such as it is used to make fire doors and Windows, fire partitions and so on.

2. Bridges and transportation: In bridge construction, hot-dip galvanized square pipe is often used in the manufacture of bridge drainage system and bridge guardrail. In addition, in traffic engineering such as highways and railways, hot-dip galvanized square pipes are widely used to make bridge signs, guardrails and pipelines for conveying goods.

3. Agriculture: In the agricultural field, hot-dip galvanized square pipes are mainly used to manufacture agricultural machinery and equipment, such as pumps, water pipes and their accessories. In buildings such as agricultural greenhouses, hot-dip galvanized square pipes as a skeleton can effectively enhance durability and stability.

4. Petrochemical industry: In the field of petrochemical industry, hot-dip galvanized square pipe is widely used in oil fields, chemical plants, natural gas pipelines and other fields. Hot-dip galvanized square pipe can be used as a pipeline for transporting oil and gas, and its corrosion resistance and good sealing characteristics can effectively protect the oil and gas inside the pipeline from being polluted.

In industrial production and civil life, hot-dip galvanized square pipe has a wide range of applications. Because the hot-dip galvanized square pipe has the characteristics of anti-corrosion and corrosion resistance, it can be used in harsh environments for a long time. Through a brief introduction to the application field of hot-dip galvanized square pipe, I believe readers will have a clearer understanding of the application scenario of hot-dip galvanized square pipe.
