In the construction project, the galvanized pipe is a very common building material, which is widely used. Basically, as long as it involves the construction engineering, the galvanized pipe must be used to the galvanized pipe. So what are the performance requirements of the galvanized pipe? Next, let's have a look with the Xiaobian of Ji'nan galvanized pipe manufacturer.
(1) high strength: generally, its yield strength is above 300MPa.
(2) 高韧性：要求延伸率为15%～20%，室温冲击韧性大于600kJ/m～800kJ/m。 对于大型焊接构件，还要求有较高的断裂韧性。
(2) high toughness: the required elongation is from 15% to 20%, and the impact toughness at room temperature is greater than 600kJ/m ~ 800kJ/m. For large welded components, high fracture toughness is also required.
(3) good welding performance and cold forming performance.
(4) low cold brittle transition temperature.
(5) good corrosion resistance.
