Galvanized steel pipe, with its zinc coating and steel composition, has been a popular choice for plumbing and industrial applications for years. Its corrosion-resistant properties and durability have made it a reliable option for transporting water and other fluids. Galvanized pipes are steel pipes that have been coated with a layer of zinc, typically through a process called hot-dip galvanization. This coating of zinc provides an additional layer of protection against corrosion, extending the lifespan of the steel pipe. We all know that galvanized steel pipes are prone to rust when exposed to water or moisture, so how to preserve galvanized steel pipes? Today we will learn about.
How to storage galvanized steel pipes?
1. Before materials are put into storage, they should be protected from rain or impurities. For materials that have been rained on or soiled, different methods should be used to clean them according to their properties. For example, a steel wire brush can be used for materials with high hardness, and cloth, cotton, etc. can be used for materials with low hardness.
2. After the materials are put into storage, they should be checked regularly. If there is rust, the rust layer should be removed.
3. Generally, the surface of steel pipes does not need to be oiled after cleaning. However, for steel, alloy steel plates, thin-walled pipes, alloy steel pipes, etc., the inner and outer surfaces must be coated with anti-rust oil after rust removal before storage.
4. For steel pipes with severe rust, it is not suitable to store them for a long time after rust removal and they should be used as soon as possible.
5. Some small steel pipes, thin steel plates, steel strips, silicon steel sheets, small-diameter or thin-walled steel pipes, various cold-rolled and cold-drawn steel pipes, and expensive and easily corroded metal products can be stored in the warehouse.
6. The warehouse should be selected according to geographical conditions. Generally, an ordinary closed warehouse is used, that is, a warehouse with a roof, walls, tight doors and windows, and ventilation devices.
7. The warehouse should be ventilated on sunny days and closed on rainy days to prevent moisture. The appropriate storage environment should be maintained at all times.
What are the maintenance methods for galvanized steel pipes?
1. Regular cleaning: During use, some dust, dirt and other dirt will accumulate. Regular cleaning can keep its appearance bright and beautiful. When cleaning, be sure to use neutral detergents and avoid using detergents containing acidic or alkaline ingredients to avoid corrosion of the galvanized layer.
2. Prevent impact: During use, care should be taken to avoid strong impact or collision with heavy objects to avoid damage to the galvanized layer, thereby affecting its anti-corrosion performance.
3. Prevent humid environment: A humid environment is one of the main causes of metal corrosion, so when using it, avoid long-term exposure to a humid environment and try to keep the galvanized pipe dry to extend its service life.
4. Regular inspection: Check the surface of galvanized steel pipes regularly to see if there is any corrosion or damage, and repair or replace them in time to ensure their anti-corrosion performance.
5. Avoid contact with other metals: When galvanized pipes come into contact with other metals, electrochemical reactions may occur, leading to corrosion of the galvanized layer. Therefore, direct contact with other metals should be avoided as much as possible during installation and use.
6. Avoid too low or too high temperature: Too low or too high temperature will affect the anti-corrosion performance of galvanized steel pipes. Try to avoid using galvanized pipes at too low or too high temperatures to avoid affecting their service life.
7. Paint regularly: As the service life increases, the coating on the galvanized steel pipe may wear or peel off, which will affect its corrosion resistance. Periodic painting can re-protect the zinc coating and prevent it from corroding.
8. Avoid excessive stretching or bending: Excessive stretching or bending can cause deformation of the galvanized steel pipe, thus affecting its use effect. Avoid excessive stretching or bending during installation and use to maintain the normal shape of the pipe.
9. Regular rust removal: Although galvanized steel pipe is a pipe with good corrosion resistance, it will also rust after long-term use. Regular rust removal can reduce the corrosion of galvanized steel pipes and extend their service life.
10. Prevent chemical corrosion: Some chemicals may damage the anti-corrosion layer of galvanized pipes. Therefore, when using galvanized pipes, avoid contact with strong acids, strong alkalis and other chemicals to avoid affecting their service life.
