Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and coating two combination. Hot dip galvanizing is to first pickling the steel tube. In order to remove the iron oxide on the surface of the steel tube, after pickling, it is cleaned in the tank of ammonium chloride or zinc chloride solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent into the hot dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel tube base and the molten bath to form a compact zinc-iron alloy layer with corrosion resistance. The alloy layer is integrated with the pure zinc layer and the steel tube matrix. Therefore, its corrosion resistance is strong.
Galvanized steel pipe is a steel pipe that has been coated with a protective layer of zinc to prevent corrosion. The galvanizing process involves dipping steel pipe into molten zinc, which bonds with the steel surface to form a durable, corrosion-resistant layer.
Galvanized steel pipe offers several advantages over other types of steel pipe, including:
1) Corrosion Resistance: The galvanized layer protects the steel pipe from rust and corrosion, making it suitable for harsh environments or applications exposed to moisture or chemicals.
2) Strength and Durability: Galvanized steel pipe is strong and durable enough to withstand heavy loads and extreme temperatures.
3) Cost-effective: Galvanized steel pipe is relatively inexpensive compared to other corrosion-resistant materials, making it a cost-effective choice for many applications.
4) Low maintenance: Galvanized steel pipe requires minimal maintenance and can last for many years if cared for properly.
5) Versatility: Galvanized steel pipe can be used in a variety of applications including construction, fabrication and transportation.
Overall, galvanized steel pipe is a reliable and cost-effective choice for many applications where corrosion resistance and durability are important factors.
Features
1. Corrosion resistance: Galvanizing is an economic and effective rust prevention method that is often used. About half of the world's zinc output is used in this process. Not only does zinc form a dense protective layer on the steel surface, but it also has a cathodic protection effect. When the zinc coating is damaged, it can still prevent the corrosion of the iron base material by cathodic protection.
2. Good cold bending and welding performance: mainly used low carbon steel grade, the requirements have good cold bending and welding performance, as well as a certain stamping performance
3. Reflectivity: It has high reflectivity, making it a barrier against heat
4, the coating toughness is strong, galvanized layer forms a special metallurgical structure, this structure can withstand mechanical damage in transport and use.
Application
GI Coil stands for Galvanized Iron Coil and is a popular material used in a wide variety of industries. Here are some common applications for GI coils:
1. Construction: GI rolls are widely used in roofs, wall panels, fences and frame structures in the construction industry. Its galvanized coating prevents rust and corrosion, making it suitable for outdoor applications.
2. Automotive: GI coils are used in the automotive industry to make body panels, body parts, and other components. Its high strength and durability make it a popular choice for automotive applications.
3. HVAC: GI coils are used in heating, ventilation, and air conditioning (HVAC) systems for the manufacture of ductwork, air handlers, and air filters. A galvanized coating protects it from corrosion and prolongs its life.
4. Household appliances: GI coils are used in the manufacture of household appliances such as refrigerators, washing machines, and clothes dryers. Its corrosion resistance and high strength make it a suitable material for home appliance applications.
5. Electrical: GI coils are used in the electrical industry to make conduits, cable trays and electrical enclosures. Its durability and corrosion resistance make it ideal for electrical applications.
6. Agriculture: GI coils are used in agriculture to make fences, sheds and chicken coops. Its galvanized coating resists rust and weather damage, making it ideal for outdoor agricultural applications.
Overall, GI coils are a versatile material that can be used in many applications across a variety of industries. Its galvanized coating prevents rust and corrosion, making it suitable for outdoor and harsh environments.
