Astm Hot Dip Ms GI Galvanized Welded Carbon Steel Round Pipe
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.
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
Galvanized coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. The construction industry is mainly used for the manufacture of anti-corrosion industrial and civil building roof panels, roof grids, etc. The light industry uses it to manufacture household appliance shell, civil chimney, kitchen utensils, etc., and the automobile industry is mainly used to manufacture corrosionproof parts of cars. Agriculture, animal husbandry and fishery are mainly used as food storage and transportation, meat and aquatic products frozen processing equipment, etc. Commercial mainly used as material storage and transportation, packaging tools,

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.
