What is CP Brass Angle Valve
what is cp brass angle valveCP brass angle valve is a kind of angle valve whose surface are Chrome-plated. It is usually installed on a tiled wall, so that it is more convenient for us to use. CP brass angle valve is usually used in the installation of faucets, toilets, water heaters, etc., and it can play the role of connecting the internal and external water pipe interfaces. The CP brass angle valve can effectively control the flow of water, which can save water to a certain extent.
What is chrome-plating for CP Brass Angle Valve
Chromium is a kind of bright white metal with bluish color. It is a method of plating a layer of chromium on metal or some non-metals by electrolysis or chemical method, so as to prevent rust and improve wear resistance. The process is called chrome plating.
Internationally, the CP brass angle valve produced by well-known kitchen and bathroom brands mostly use three-layer electroplating. That is to say, it is made of three-layer electroplating of semi-bright nickel, bright nickel and chromium layer on the forged brass angle valve body.
Nickel layers (including semi-bright nickel and bright nickel) provide corrosion resistance. Since the material of nickel itself is soft and the color is dark, the chromium layer will be plated on the nickel layer to harden the surface and improve the brightness.

The function of chrome-plating for CP Brass Angle Valve
Improve the aesthetics:
The CP brass angle valve surface treated by chrome-plating presents a bright mirror texture, which can be used as a mirror for clear reflectionImprove anti-corrosion performance:
Regardless of surface treatment such as chrome-plating or matte, the most practical purpose is to prevent the CP brass angle valve substrate from being corroded by water and air, resulting in damage to the substrate and affecting the health of water quality.
How to inspect the electroplating quality of the CP brass angle valve
There is a professional test in the industry: the Acetic Acid Salt Spray Test (AASS).
Use a special salty spray test machine (as below) to simulate a high-concentration acidic salt spray environment. Compared with the natural environment, the salt concentration of chloride in the salt spray used in the test is several times or dozens of times that of the general natural environment salt spray, which greatly improves the corrosion rate and can quickly test the corrosion resistance of the product's electroplating layer. . Through the salt spray test of the product, the test result can be obtained quickly and accurately.
For the salt spray test standard of electroplating products, please refer to "Rating of Specimens and Specimens after Corrosion Test of Metal and Other Inorganic Caps on Metal Substrates". Whether the electroplating of CP brass angle valve products meets the standard is mainly based on the protection rating, that is, the corrosion area The percentage of the ratio to the total area is divided into several grades according to a certain method, and a certain grade is used as the basis for qualified judgment.
acetic acid salt spray test for cp brass angle valve
According to the existing national standard, the CP brass angle valve electroplating acid salt spray test reaches grade 9 for 24 hours, which is a qualified product, and some manufacturers with strong technical level can maintain the electroplating effect at grade 10.
Note that the salt spray rating does not mean that the longer the test time, the better the plating effect, the key lies in the achieved rating. For example, level 10 in 24 hours and level 9 in 48 hours, then the good electroplating effect is level 10, and the time can meet the requirements of the national standard.
If the product can meet the test time and the highest protection rating far exceeding the national standard, it means that the electroplating quality is high, it is more resistant to corrosion after installation, and it can remain bright and clean for a long time.
Other tests to CP Brass Angle Valve
other tests to cp brass angle valveExcept for AASS test, the CP brass angle valves are strictly tested in our lab, such as brass material test, flow rate test, torque test, body reistance test, all these tests are used to ensure each CP brass angle valve we produce are up to top and professional quality requirements.
