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 round pipe is introduced

Hot-dip galvanized round pipe is mainly used in construction, petrochemical, manufacturing and other fields of anti-corrosion, wear, high temperature and other applications. 


First, the construction field  

1. Building materials  

Hot-dip galvanized round pipe is widely used in the field of building materials, such as steel structure, stairs, railings, pipelines in mainframes, etc., because it can effectively enhance the corrosion resistance of materials and extend the service life.  

2. Architectural decoration  

Hot-dip galvanized round pipe is also used in the field of architectural decoration, such as architectural appearance design, geological disaster prevention engineering, etc., its surface brightness is high, and it is widely used.  


Second. Petrochemical field  

There is a great demand for pipelines in the petrochemical field, and hot-dip galvanized round pipe, as a material with excellent anti-corrosion and wear-resistant properties, is widely used in oil, natural gas, petrochemical and other fields.  


Third, the manufacturing field  

1. Mechanical manufacturing  

The field of mechanical manufacturing has high requirements for wear resistance and corrosion resistance of metal materials, and hot-dip galvanized round pipe has excellent anti-corrosion and wear resistance characteristics, so it is widely used in the field of mechanical manufacturing.  

2. Vehicles  

Nowadays, a large number of hot-dip galvanized round pipes are used in cars, trains and other transportation vehicles, mainly for braking systems, exhaust systems, hydraulic systems and so on.  

In summary, in addition to the above fields, hot-dip galvanized round pipes are also used in many fields such as modern agriculture and shipbuilding.  Hot-dip galvanized round pipe has good corrosion resistance, wear resistance and high temperature resistance, and is an important material widely used in industrial fields.
