Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Cold galvanized steel pipes have been banned, and the latter is also advocated for temporary use by the state. In the 1960s and 1970s, developed countries began to develop new types of pipes, and gradually banned galvanized pipes.

Hot Dip Galvanizing refers only to coatings formed by immersing steelwork into molten zinc. However, there are two variations of the Hot Dip Galvanizing processes:Batch Galvanizing and Pregalvanizing. Batch Hot Dip Galvanizing Difference Between Pre - Galvanized And Hot- Galvanized Pre-galvanizing pipe,also known as mill galvanized pipe, hot dip mill galvanized or continuous hot dip galvanized.Pre-galvanized steel pipe refers to pipe which was galvanized while in sheet format, thus prior to further manufacturing. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled.the pipe thickness

ERW HOT DIP GALVANIZED STEEL PIPES Hot Galvanized Steel pipe is a pipe that has been dipped into a molten zinc bath. The layer of zinc provides a protective boundary, permitting steel to be used in moderately corrosive services and outdoors services. Standards:ASTM A106, ASTM 53, Hot Dipped Galvanized Round Steel PipeMay 15, 2016 · Hot Dipped Galvanized Round Steel Pipe 1.Product advantages:Hot galvanizing has the advantages of uniform coating, strong adhesion and long service life.Complex physical and chemical reactions take place between the hot galvanized steel tube matrix and the molten bath to form a tightly corrosion resistant zinc-ferroalloy layer.
Hot Dipped Galvanized Steel Pipe. Hot-dip galvanized steel pipes are those steel pipes that have been covered with a layer of zinc metal. During galvanized, steel pipe is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc's natural corrosion resistance provides long-term protection, even in outdoor environments. Hot dipped galvanized round pipe - jnsteelpipeHot dipped galvanized round pipe is the main structural low liquid steel material in the water, chemical transfer, energy project, scaffolding, structural project etc. It will be manufactured by ERW & HFW. The fabrication process by hot dipped zinc coating thickness is 220g/m2-800g/m2, The main advantage is the zinc coating will be the big thickness, anticorrosive is good.
