Oct 12, 2017 · Steel and iron often earn their rust-resistance through galvanization, which involves coating the material in zinc. There are several alternatives for carrying this out, but hot-dip galvanizing (HDG)the process of dipping steel into a kettle or vat containing molten zincis advantageous due to its inherent simplicity. However, regardless of its relatively basic procedure and resulting
With the different processing technology of steel pipe such as hot dipped galvanized steel pipe, the classification of steel pipe is in a varieties, which lead to a large choice scope for customers in the steel pipe market.Before choosing steel pipes, we need to get clear of the pipe properties so as to guarantee the project smooth as well as safe.

China Hot Dipped Galvanized Square Steel Pipe Because of this, the production of electrogalvanized pipes is greatly limited. Hot-dip galvanized pipe and electro-galvanized pipe are fundamentally different in the microstructure of the coating. There is a layer of slightly brittle compound between the pure zinc coating of the hot-dip galvanized pipes and the base of the steel strip.
Mar 29, 2011 · Both the black pipe as well as galvanized pipe is made of steel. While galvanized pipe has a zinc coating, black pipe does not have it Because it corrodes easily, black pipe is more suitable for carrying gas. On the other hand, galvanized pipe is Difference Between Galvanized and Hot Dip Galvanized Jul 02, 2019 · The key difference between galvanized and hot dip galvanized is that most galvanized materials have a smooth and sharp finishing, whereas hot sip galvanized structures have a rough finishing.. Galvanization is a process of preventing metal surfaces from corrosion.After the completion of galvanization, we say that the surface is galvanized if it is done via the usual procedure.
The most common is hot-dip galvanization, in which the iron is moved through an extremely hot bath of molten zinc, which may be mixed with small amounts of lead, depending on the circumstances. When the iron emerges from the bath, the zinc will have bonded, creating a layer of zinc on the surface of the iron. Mild steel pipe( seamless steel GALVANIZED IRON PIPES (G.I. PIPES) - Solid SteelGALVANIZED IRON PIPES (G.I. PIPES) Galvanized Iron (G) Pipes refers to the surface treatment of the pipes, whereas it is treated or coated with zinc coating through hot-dipped zinc bath. It is applicable only to carbon steel pipes. Galvanized Iron Pipes are manufactured using mild steel strips of Low Carbon Steel Coils.
With galvanized plating, a process called hot-dip galvanizing is used, which is a process of coating a substrate by passing the material through a molten bath of zinc at a temperature of about 460 degree Celsius. The resulting finish can be used in a place where the temperature is 200 degree Celsius and below; the zinc coating can peel when the material is exposed to temperature of more than 200 Galvanized Rigid Steel Conduit Pipe Features and ApplicationGalvanized steel pipe can be divided into two kinds, hot dip galvanized and electric zinc plating. Hot dip galvanized has the advantages of uniform coating, strong adhesion, long service life and so on. The zinc plating cost is low, and the surface is not very smooth.
