Hot-dipped Galvanized spiral welded pipe

Hot-dipped Galvanized spiral welded pipe Hot-dipped Galvanized spiral welded pipe

Product name:Hot-dipped Galvanized spiral welded pipe

Item:LX-005

Details:

 Hot dip galvanized spiral welded pipes refers to the spiral welded pipes by hot dip galvanizing progressing in order to get the anti-corrosion effect, it’s used mainly on the pipe piles bare on the ground.

 

Hot-dip galvanization is a form of galvanization. It is the process of coating iron, steel or aluminium with a layer of zinc by immersing the metal in a bath of molten zinc at a temperature of around 860 °F (460 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and can be identified by the crystallization patterning on the surface (often called a "spangle").

 

And for the spiral welded pipe it’s more economical than LSAW pipes and can reach more length than the LSAW or seamless pipes due to their different formation. Hot-dipped Galvanized spiral welded pipes can be widely used the structural supports, pipe piles, mining etc. We can produce bare spiral welded pipes and can also do the galvanization for the spiral welded pipes, and our galvanized spiral welded pipes could reach thick zinc coating thickness in accordance with our customer’s requirements.
