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.

 
The chromium-plated layer has a very high hardness, and its hardness can vary within a wide range of 400-1200HV according to the composition of the plating solution and process conditions. The chromium-plated layer has good heat resistance. When heated below 500℃, there is no obvious change in gloss and hardness. The temperature above 500℃ starts to oxidize and discolor, and the hardness starts to decrease when the temperature exceeds 700℃. 
 
During the chromium plating process, there is a mutual dependence between the cathode current density and the temperature. When chromium plating in the same solution, by adjusting the temperature and current density, and controlling them within an appropriate range, three chromium plating layers with different properties can be obtained: bright chromium, hard chromium and opal chromium. In the low-temperature and high-current-density area, the chromium coating is dark or charred. This coating has network cracks, high hardness and high brittleness; in the high-temperature and low-current density area, the chromium layer is milky white, with fine structure, few pores, and no pores. Cracks, good protection performance, but low hardness, poor wear resistance; when the middle temperature and middle current density area or the two are better, a bright chrome layer can be obtained. This chrome layer has higher hardness and has fine and dense network cracks.
When the current density is constant, the current efficiency decreases with the increase of temperature; if the temperature is fixed, the current efficiency increases with the increase of the current density. However, when the ratio of chromic anhydride to sulfate ion decreases, the change becomes smaller accordingly. Therefore, in the case of hard chromium plating, under the premise of meeting the performance of the coating, a lower temperature and a higher cathode current density are usually used to obtain a higher deposition rate of the coating. When the temperature is constant, with the increase of the current density, the dispersion ability of the plating solution is slightly improved; on the contrary, the current density remains unchanged, and the dispersion ability of the plating solution decreases to a certain extent as the temperature of the plating solution increases. Generally, medium temperature (45~60℃) and medium current density (30~45A/dm2) are used in production to obtain bright and hard chrome coating.
