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 pipes are also used in building materials, home appliances, automobiles, and other industries because these industries more or less involve the support of steel structures. The emergence of galvanized steel pipes has solved this problem ingeniously. Demand will continue to increase.

3. In addition to being widely used in industrial production, galvanized steel pipe also plays an important role in modern buildings, factories, space structures, transportation energy, etc. The application of galvanized steel pipe in these fields mainly serves as a protective film In this way, the erosion effect of the outside world on the object is weakened.

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 and brittle transition temperature.

(5) Good corrosion resistance.

Advantage

1. Low processing cost: the cost of hot-dip galvanizing and anti-rust is lower than that of other paint coatings;

2. Durable and durable: hot-dip galvanized steel pipe has the characteristics of a glossy surface, uniform zinc layer, and strong corrosion resistance. In areas or offshore areas, the standard hot-dip galvanized anti-rust layer can be maintained for 20 years without repair;

3. Good reliability: the metallurgical bond between the galvanized layer and the steel material becomes a part of the steel surface, so the durability of the galvanized layer 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 plated parts can be galvanized, even in the depressions, sharp corners, and hidden places can be fully protected;

6. Saving time and labor: the galvanizing process is faster than other coating construction methods, and can avoid the time required for painting on the construction site after installation.
