Steel pipes (such as seamless pipes and welded pipes) are easily rusted or even completely damaged in air, water or soil. Annual steel loss due to corrosion accounts for about 1/10 of the entire steel production. On the other hand, the surface of steel pipes and parts has certain special functions, and at the same time gives them a decorative appearance, so they are generally treated by galvanizing.
Application field of hot-dip galvanized pipe
1. Galvanized steel pipes are mainly used in agricultural machinery, grain storage and high-speed guardrails in daily life. Its outstanding feature is low cost and high added value.
2. Galvanized steel pipe is also used in building materials, home appliances, automobiles and other industries. The emergence of galvanized steel pipes solves the support problems of steel structures in these industries.
3. In addition to being widely used in industrial production, galvanized steel pipe also plays an important role in modern buildings, factories, space structures, and transportation energy. The application of galvanized steel pipe in these fields mainly plays the role of protective film, which weakens the erosion effect of the outside world on objects.
Hot-dip galvanized pipe performance requirements
1. High strength: generally its yield strength is above 300MPa.
2. High toughness: the elongation is required to be 15% to 20%, and the impact toughness at room temperature is greater than 600kJ/m to 800kJ/m. Large welded components also require high fracture toughness.
3. Good welding performance and cold forming performance.
4. Low cold-brittle transition temperature.
5. Good corrosion resistance.
The point of excellent hot-dip galvanized pipe
1. Low processing cost. The cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings.
2. Long-lasting and durable. Hot-dip galvanized steel pipe has the characteristics of glossy surface, uniform zinc layer, no missing plating, no dripping, strong adhesion and strong corrosion resistance. In the suburban environment, the standard hot-dip galvanized anti-rust thickness can be maintained for more than 50 years without repairing. In urban areas or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repairing.
3. Good reliability. The metallurgical bonding between the galvanized layer and the steel is good news, and it becomes a part of the steel surface, 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 that can withstand mechanical damage during transportation and use;
5. Comprehensive protection. Every part of the plated parts can be coated with zinc, even in the recesses, sharp corners and hidden places can be fully protected;
6. Save time and effort. The galvanizing process is quicker than other coating application methods and avoids the time required to paint on the job site after installation.
