Carbon steel seamless elbow should not contact water

With the rapid development of the seamless elbow industry, many elbow enterprises have continuously achieved leapfrog development, and have experienced four stages such as workroom-style start, large-scale expansion and industrialization development and upgrading and speeding up in this century.

Carbon steel seamless elbows should not touch water

Because some of the components are contradictory, so what is the specific principle of the need to use the corrosion resistance of reducing substances, especially the partial corrosion resistance of chloride

Improving the high temperature physical properties of martensitic stainless steel pipes, it improves the reliability of passivation film, improves the hardness and quenching reliability of carbon steel seamless elbows, and makes stainless steel have stronger corrosion resistance.

Carbon dioxide gas is the impurity residue in water, which is produced in the free state under normal conditions, and a large number of bicarbonate in water is also produced in the free way of carbon dioxide gas at low pH, so the uniform phenomenon of carbonic acid is produced

If the more carbon dioxide gas in the water, the more H+ is converted, the lower the pH value of the water, the acid etched water will be produced. Thereby destroying the protective film generated by the carbon steel skin, resulting in corrosion of carbon steel.

If the removal of carbon dioxide gas into the brine, it will cause the electricity of the water will be increased, and the corrosion will be increased. Therefore, the demineralized water tank should prevent the carbon dioxide gas from melting into the storage tank. We can protect the area above the storage tank with nitrogen or other inert gases to prevent carbon dioxide gas from destroying the quality of pure water.

Carbon dioxide gas is a commonly used chemical substance in the air, improve the hardness and quenching reliability of carbon steel seamless elbow, carbon dioxide gas molecules by two oxygen atoms and 1 carbon atom through chemical bonding, 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, react with water into carbonic acid, but it can not be burned, solid carbon dioxide gas is often called dry ice.

The above is the reason why the carbon steel seamless elbow can not touch the water, and I hope that you will pay attention to the case of using carbon steel seamless elbow, so that you can use carbon steel seamless elbow more strongly
