Hot-dip galvanizing
Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer to ensure that the matrix as well as the finishing are incorporated. The hot-dip galvanizing action for pipe installations is to first degrease the pipe fittings, and after that pickling to remove iron oxide externally of the steel pipeline. After that, the pipeline fittings are submersed in a plating container where zinc has actually been warmed and thawed beforehand, and also a zinc layer is formed on the surface of the pipe installations, and finally, it can be lifted out.
Warm dip galvanizing is a chemical therapy. A complicated chemical reaction takes place in between the base of the pipeline suitable and the molten zinc to develop a zinc-iron alloy layer with deterioration resistance and also a small structure. The alloy layer is incorporated with the pure zinc layer and the pipeline suitable matrix. Warm dip galvanized pipe fittings have strong deterioration resistance.
Electro-galvanizing
Cold galvanizing is also called electro-galvanizing. The amount of galvanizing is really small, just 10-50g/ m2, and also the zinc layer is independently layered from the base of the pipeline fittings. Electrolytic galvanizing is to make use of electrolysis to make the zinc layer merely comply with the base of the pipeline fittings, and it is very easy to diminish, so its corrosion resistance is poor.
The action of cool galvanizing for pipeline fittings is to initially degrease and also pickle the pipeline fittings, and also then use electrolysis tools to place them right into an option of zinc salt, and also connect the unfavorable electrode of the electrolysis tools. Cold galvanizing is a physical therapy, simply clean a layer of zinc on the surface area, so the zinc layer of pipe installations is easy to drop off.
The difference
Although it is challenging to see the distinction between the type of pipe installations externally, essentially, they are really various.
Hot-dip galvanized pipe fittings have the advantages of uniform covering, strong adhesion, and long service life. In regards to zinc layer thickness, hot-dip galvanizing is dozens of times that of cool galvanizing, as well as the rust resistance is also dozens of times that of electro-galvanizing.
Electro-galvanized pipeline installations have an inexpensive, reasonably cheap cost, as well as a bright and fragile appearance.
Hebei Jianzhi Spreading Team, adhering to years of research and development, has actually made a considerable innovation in electro-galvanizing, making the surface of electro-galvanizing almost the same as that of hot-dip galvanizing. This innovation has been provided a Chinese design patent. The number listed below illustrates a screen of hot-dip galvanized pipe fittings and also electro-galvanized pipe installations generated by Hebei Jianzhi Casting Group.
Types of Galvanized Pipe Fittings
Galvanized malleable iron pipeline fittings connect to piping for delivering fuel oil, water, gas, and also various other fluids for chemical, waste incineration, and semiconductor sector applications. These installations are pipeline with thick walls, fertilized galvanized pipe fittings catalog with a safety zinc covering that shields against corrosion, mineral, as well as rust build-up as well as stands up to damp problems. Threaded galvanized pipe fittings are offered in a selection of sizes and also forms

The hot-dip galvanizing step for pipe installations is to initial degrease the pipeline installations, and after that pickling to get rid of iron oxide on the surface of the steel pipe. The pipeline installations are immersed in a plating storage tank where zinc has been warmed as well as melted in development, as well as a zinc finishing is formed on the surface area of the pipe installations, and lastly, it can be lifted out.
The step of cool galvanizing for pipe installations is to initially degrease as well as marinade the pipe installations, as well as after that use electrolysis equipment to place them right into a service of zinc salt, as well as link the unfavorable electrode of the electrolysis devices.
