Sulfate galvanized conversion in hot galvanized steel pipe

    How could we forget the sulfate galvanized conversion when we talked about the process characters of galvanized steel pipe. Today, as manufacturer of steel pipes, Tianjin xinyue steel would have a list for sulfate galvanized conversion in hot galvanized steel pipe.

    Sulfate galvanized conversion:

    Sulfate galvanized ferroalloy retains only the main salt of zinc sulphate zinc sulfate, and the remaining components, such as aluminum sulfate, alum (potassium aluminum sulfate) can be added in the treatment. This would finally lead to the formation of insoluble hydroxide precipitate precipitation. For organic additives, we can add powdered activated carbon adsorption to remove it. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove in once. And this has a certain degree influence for brightness for brightness of the coating, but it is not serious, as it can be taken out of consumption, which make coating brightness can be restored. The solution passed the treatment, according to the new Process ingredients required additional content, that is the final complete the conversion.

Spiral welded pipe for sewage treatment

With the acceleration of urbanization, sewage treatment has become an increasingly prominent issue. In the field of sewage treatment, spiral welded pipes (ssaw), as an important pipeline material, have been widely used. The following will introduce the application and characteristics of spiral welded pipes in sewage treatment. Advantages of spiral welded pipe: 1. Strong corrosion resistance During the production process of spiral welded pipe, due to its special manufacturing process, it has stronger corrosion resistance. Compared with traditional steel pipes, spiral welded pipes can better adapt to various environments and effectively resist the erosion of various chemical substances. 2. Long service life Because spiral welded pipes have greater corrosion resistance and higher strength, they have a longer service life than traditional steel pipes. In sewage treatment systems, the durability of pipes is very important, and spiral welded pipes can exactly meet this requir...
