Carbon steel seamless elbows should not come into contact with water
Carbon steel seamless elbow is not able to reach the water, because some components, will be contradictory, so what is the specific principle, need to use corrosion resistance in reducing substances
Especially the partial corrosion resistance of chloride, improve the high-temperature physical properties of martensitic stainless steel pipe, improves the reliability of passivation film, improves the hardness of carbon steel seamless elbow and quenching reliability so that stainless steel has stronger corrosion resistance.
Carbon dioxide gas is the impurity residue in water, which is produced in the free state under normal conditions. Large quantities of bicarbonate in water are also produced in the free way of carbon dioxide gas at low pH, so the uniform phenomenon of carbonic acid is produced
The more carbon dioxide in the water, the more H+ is converted, and the lower the pH of the water, resulting in acid-etched water. This destroy the protective film generated by the carbon steel skin, resulting in carbon steel etching.
Carbon steel seamless elbow without water
If carbon dioxide gas is added to the brine, the electricity of the water will be increased, and the corrosion will also be increased. Therefore, the debrine tank should avoid carbon dioxide gas melting into the storage tank.
We can protect the area above the tank with nitrogen or other inert gas to prevent carbon dioxide gas from damaging the quality of the purified water
Carbon dioxide gas is a commonly used chemical substance in the air, which improves the hardness and quenching reliability of carbon steel seamless elbow. Carbon dioxide gas molecules are composed of two oxygen atoms and one carbon atom through chemical bonds. Carbon dioxide gas and oxygen reflect the molecular formula of carbon dioxide gas
At room temperature, it is odorless air, relatively denser than air. It can dissolve in water and react with water to form carbonic acid, but it cannot be burned. Solid carbon dioxide gas is often referred to as dry ice, for the reason that water cannot be touched
Carbon steel seamless elbow popular reason
The processing temperature of the product in processing depends on the carbon content of the product material. In the process of processing, the main compressive stress of the inner wall of the product is less than the yield limit of the material at this temperature. The higher the austenitizing temperature and heating temperature, the higher the yield limit and heating temperature
The higher advantage of seamless steel pipe is, seamless elbow material is composed of carbon and hydrogen, carbon steel seamless elbow material has been inspected by the relevant departments, safety is guaranteed, seamless elbow has good heat resistance
Seamless elbow strong corrosion resistance, in addition to a small amount of hydrogenating agent, will not rust, breeding bacteria. The thermal insulation performance is good because the thermal conductivity of the seamless elbow material is very low, compared with the thermal insulation material is very good.
I believe that many friends are aware of the advantages of the product above. In addition, there is also a point that is very compared to mention that the service life of carbon steel seamless elbow is very long
It is said that for more than 50 years, its rated temperature and pressure, will not only emit radiation and ultraviolet rays but also make the products never fade, a wide variety of applications is forming a large-scale high-tech industrial cluster, with very broad market prospects
The above and carbon steel seamless elbow related characteristics hope through the above, can further understand the advantages of carbon steel seamless elbow products
