Galvanized pipe manufacturers in Ji'nan say that galvanized pipe is a very common building material in construction engineering. It is widely used in a wide range. As long as it involves building engineering, it can't be used to galvanized pipe. What are the performance requirements of galvanized pipe?
(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.
