Cold galvanized pipe
Short Description:
As the name suggests, cold galvanized pipe is a steel pipe coated with a layer of zinc on the outer wall of the steel pipe by electro galvanizing. This treatment method is completely different from the principle of hot galvanizing, so we call it cold galvanized pipe.
In the past, cold galvanized pipes were often used in gas and tap water supply systems, as well as other aspects of fluid transportation and heating supply. Now, the cold galvanized pipe has basically withdrawn from the field of fluid transportation, and the cold galvanized pipe will still be used in some fire water and ordinary frame structures, because the welding performance of this pipe is still very good.
