In modern industrial production, more and more specialized equipment positions are widely used, and seamless steel pipes are a common type. It is worth mentioning that hot-dip galvanized seamless steel pipes have good performance, good quality, long service life, and have shown excellent performance in modern industrial production, which has been selected by many industrial enterprises. So, what is its primary role? The first effect is that the coating is uniform, and the adhesion it exhibits is very robust. Executives who use other equipment to produce products may have uneven, unsmooth, or uneven coatings on the surface. However, hot-dip galvanized seamless steel pipes are completely different. Their surface layer is made of hot-dip galvanized material, which is applied evenly and can adhere well to the seamless steel pipes, exhibiting super strong adhesion. The second function is that its generalization has a long lifespan and a long usage time, which can maximize its effectiveness. From the perspective of process principle, when using hot-dip galvanized materials, the first step is to conduct professional acid pickling on the steel pipe, successfully removing some iron oxide components attached to the surface of the steel pipe, and then applying hot-dip galvanized materials on it, forming a hot-dip galvanized seamless steel pipe. By applying this principle, the lifespan of the steel pipe produced is very long, and there are few problems or shortcomings throughout the entire application process, which will not affect its practical application.
The functional impact of precision galvanized steel pipes
1. Carbon; The higher the carbon content, the higher the hardness of steel, but its plasticity and resistance are poorer
2. Sulfur; It is a harmful impurity in steel. Steel with high sulfur content undergoes simple brittle cracking during pressure processing at high temperatures, commonly referred to as thermal brittleness
3. Phosphorus; It can significantly reduce the plasticity and resistance of steel, especially at low temperatures, which is called cold brittleness. In high-quality steel, sulfur and phosphorus should be strictly controlled. However, from another perspective, low carbon steel contains high levels of sulfur and phosphorus, which can make it easy to cut and improve the machinability of steel
4. Manganese; It can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical functions
5. Silicon; It can improve the hardness of steel, but its plasticity and resistance decrease. Steel used for electrical purposes contains a certain amount of silicon, which can improve the soft magnetic function
6. Tungsten; It can improve the red hardness and thermal strength of steel, as well as the wear resistance of steel
7. Chromium; It can improve the hardenability and wear resistance of steel, improve its corrosion resistance and oxidation resistance
How to remove rust from precision galvanized steel pipes?
1. Firstly, clean the surface of the steel with solvent to remove any organic matter on the surface,
2. Then use something to remove rust (wire brush), remove loose or tilted plans, rust, welding slag, etc,
3. Use acid washing method.
