High Quality Gi Galvanized Steel Iron Pipe Steel Tube for Sale
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.
The production process of galvanized steel pipe includes the following steps:
1. Steel coils: Galvanized steel pipes are made of high-quality steel coils that are hot-rolled to the desired thickness and shape.
2. Cleaning: The steel coil is cleaned to remove any rust, oil or other impurities that may affect the quality of the final product.
3. Flux: The coil is passed through a flux bath containing a zinc ammonium chloride solution. This solution helps to remove any remaining impurities and prepares the steel surface for the next step.
4. Galvanizing: Dip the coil in molten zinc to completely cover the steel surface. This process is sometimes called hot dip galvanizing.
5. Cooling: Cool the coil after galvanizing to solidify the zinc layer.
6. Cutting and forming: The coil is then cut to the desired length and formed into tubing.
7. Testing: Tubes are tested to ensure they meet the required standards for strength, durability and corrosion resistance.
8. Storage and distribution: The tubes are then stored and distributed to customers.
The production process of galvanized steel pipe is relatively simple and produces a high quality, durable product suitable for a wide range of applications.
Features
Galvanized pipe is the strip steel or coil sheet bending according to the spiral shape, with double-sided submerged arc automatic welding of the inner seam and outer seam welding made of galvanized pipe, due to the following reasons it can be widely used in construction, machinery, coal mine, chemical industry, railway vehicles, automobile industry, highways, Bridges, containers, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
1, low processing costs: the cost of hot dip galvanized rust prevention is lower than the cost of other paint coatings.
2, durable: hot-dip galvanized steel pipe with surface luster, uniform zinc layer, no leakage plating, no dripping, adhesion strong break the net legion, strong corrosion resistance characteristics, 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 rust prevention layer can be maintained for 20 years without repair.
3, good reliability: galvanized layer and steel is metallurgical combination of good news, become a part of the steel surface galvanized steel pipe, so the durability of the coating is more reliable.
4, the toughness of the coating is strong: the galvanized layer forms a special metallurgical structure, which can withstand mechanical damage during transportation and use.
5, 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.
6, save time and effort: the galvanizing process is faster than other coating construction methods, and the time required for painting on the site after installation can be avoided.
Application
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, the latter is also advocated by the state can be used temporarily. In the 1960s and 1970s, the developed countries in the world began to develop new types of pipes and gradually banned galvanized pipes. China's Ministry of Construction and other four ministries and commissions have also issued a document to prohibit galvanized pipes as water supply pipes from 2000, the cold water pipes in the new community have rarely used galvanized pipes, and the hot water pipes in some communities use galvanized pipes. Hot-dip galvanized steel pipe has a wide range of applications in fire, power and highway

Galvanized steel round tube packaging usually includes the following steps:
1. Galvanized steel round pipes are inspected for any defects or damages before packing.
2. Then use metal or plastic straps to tie the tubes together to hold them securely in place.
3. Then put the bundled tubes on a pallet or in a crate, and add cardboard or wooden spacers between each layer of tubes to prevent mutual friction during transportation.
4. The pallet or crate is then wrapped with protective plastic film to further secure the tube and prevent any moisture or debris from getting inside.
5. Finally, the tube is affixed with information such as size, quantity and any other relevant details to aid storage and identification at destination.
Proper packaging of galvanized steel round pipes is very important to ensure that they arrive at their destination in good condition with minimal damage or corrosion.
Galvanized pipe is a common building material and is used in a wide range. In the process of shipping, due to the influence of environmental factors, it is easy to cause problems such as rust, deformation or damage to the steel pipe, so it is very important for the packaging and transportation of galvanized pipes. This paper will introduce the packaging method of galvanized pipe in the process of shipping.
2. Packaging requirements
1. The surface of the steel pipe should be clean and dry, and there should be no grease, dust and other debris.
2. The steel pipe must be packed with double-layer plastic coated paper, the outer layer is covered with a plastic sheet with a thickness of not less than 0.5mm, and the inner layer is covered with a transparent polyethylene plastic film with a thickness of not less than 0.02mm.
3. The steel pipe must be marked after packaging, and the marking should include the type, specification, batch number and production date of the steel pipe.
4. The steel pipe should be classified and packaged according to different categories such as specification, size and length to facilitate loading and unloading and warehousing.
Third, packaging method
1. Before packaging the galvanized pipe, the surface of the pipe should be cleaned and treated to ensure that the surface is clean and dry, so as to avoid problems such as corrosion of the steel pipe during shipping.
2. When packaging galvanized pipes, attention should be paid to the protection of steel pipes, and the use of red cork splints to strengthen both ends of the steel pipes to prevent deformation and damage during packaging and transportation.
3. The packaging material of galvanized pipe must have the effect of moisture-proof, water-proof and rust-proof to ensure that the steel pipe is not affected by moisture or rust during the shipping process.
4. After the galvanized pipe is packed, pay attention to moisture-proof and sunscreen to avoid long-term exposure to sunlight or humid environment.
4. Precautions
1. Galvanized pipe packaging must pay attention to the standardization of size and length to avoid waste and loss caused by size mismatch.
2. After the packaging of galvanized pipe, it is necessary to mark and classify it in time to facilitate management and warehousing.
3, galvanized pipe packaging, should pay attention to the height and stability of the goods stacking, to avoid the tilt of the goods or stacking too high to cause damage to the goods.
The above is the packaging method of galvanized pipe in the shipping process, including packaging requirements, packaging methods and precautions. When packaging and transportation, it is necessary to operate in strict accordance with the regulations, and effectively protect the steel pipe to ensure the safe arrival of the goods at the destination.
