Description

Threaded couplings refer to pipe connections with threads, which are the most common type of pipe fittings in industry and life.
The meaning of threaded coupling is: threaded joints make the connection of the pipeline easier, and it is easier to disassemble and replace, which greatly saves the cost of pipeline connection.

 

Color Zinc plated

Using chemical or electrochemical methods, a colored film or interference film is produced on the metal surface. The film is very thin, and sometimes the interference film itself has almost no color. When the surface of the metal and the film reflect light, the light waves cancel each other out. , Forming a variety of different colors, when the thickness of the film gradually decreases, the color tone changes, generally from yellow, red, blue to green, until the color of the film itself is displayed. If the thickness of the film is not uniform, it will produce rainbow Variegated or variegated.
There is also a dyeing process to make the metal surface color. It is mainly through a large number of micropores on the metal surface or strong adsorption and chemical reaction on the metal surface to uniformly dye the inorganic or organic dyes in the dyeing solution to the metal surface. Sometimes electrolysis can be used to co-deposit metal ions and dyes to produce colors.
After the passivation of the zinc coating, the passivation film or white passivation film of different colors is usually obtained depending on the passivation solution used. The corrosion resistance of the rainbow-colored passivation film is more than five times higher than that of the colorless passivation film. This is because the rainbow-colored passivation film is thicker than the white passivation film; on the other hand, when the surface of the rainbow-colored passivation film is scratched, in humid air, the hexavalent chromium in the passivation film near the scratched part will be rubbed. The injured part undergoes a "re-passivation" effect to repair the damage and restore the integrity of the passivation film.
