Does 304 stainless steel pipe also rust? How to solve the rust?

[guidebook] : 304不锈钢管越来越多地应用到大家的日常生活中。因其光亮易洗，不易生锈，不但表面美观，而且结实。但是，304不锈钢管并不是绝对不生锈的。不锈钢水管之所以能不锈，就是因为有铬和镍的存在，降低这两种成分的含量会降低防锈性能，也可能是表面粘附有酸性、碱性和酸性化学品，也可能是与其它金属材料表面粘结住也会导致304不锈钢水管生锈。

304 stainless steel tube is more and more used in everyone's daily life. Because it is bright and easy to wash, not easy to rust, not only the surface is beautiful, but also strong. However, 304 stainless steel pipe is not absolutely rust-free. The reason why stainless steel water pipe can not rust is because of the presence of chromium and nickel, reduce the content of these two components will reduce the anti-rust performance, may also be adhered to the surface of the surface with acidic, alkaline and acidic chemicals, may also be bonded to the surface of the surface of the other metal materials can also lead to the rust of 304 stainless steel water pipe.

First, why stainless steel water pipe will rust

Stainless steel has the ability to resist atmospheric oxidation as well as stainlessness, and also has the ability to resist corrosion in media containing acids, alkalis and salts and corrosion resistance. However, the corrosion resistance of steel varies with the chemical composition of steel, the state of steel, the conditions of use and the type of environmental media. For example, 304 steel pipe, in a dry and clean atmosphere, has excellent resistance to rust and corrosion, but move it to the seaside area, in the sea spray containing a large amount of salt, it will soon rust. Therefore, not any kind of stainless steel, at all times can resist corrosion, not rust.

Stainless steel is a layer of extremely thin, firm, fine, stable chromium-rich oxide film (protective film) formed on its surface, which prevents the continuous penetration and oxidation of oxygen atoms, thus gaining the ability to resist corrosion. Once there is some kind of social reason, this film has been we constantly carry on the destruction, air or liquid oxygen atoms will be through the continuous development of infiltration or metal iron atoms constantly precipitated out, the formation of loose iron oxide, the surface of the metal material is not subject to the enterprise constantly rusting.

Second, 304 stainless steel pipe rust solution

However, rust and not rust are relative, 304 stainless steel pipe is not not rust, just relatively not easy to rust, reduce its chance of rust just. Below is a list of several situations in which rust occurs and the solution of 304 stainless steel water pipe rust:

1, other metal materials and stainless steel pipe wall bonding when the probability of rust. Other metal materials attached to the stainless steel pipe caused by the rust situation is generally not very serious, you can use a sponge or cloth, will be neutralized cleaner, whitening toothpaste or soapy water, etc. clean up, but also stainless steel pipe inside the rust clean.

2, stainless steel surface adhesion of organic compounds liquid juice (such as fruits and vegetables, soup, sputum, etc.), in the presence of ice and oxygen, constituting organic matter, long time will be organic matter immersed in the surface of metal materials.

3, stainless steel surface adhesion with acidic, alkaline and acidic chemicals (such as indoor decorative wall of edible alkali, splash water), resulting in partial corrosion.

4, when there are more harmful substances in the exhaust pipe, stainless steel pipe is also very easy to cause rust. Such as in the processing plant or city street traffic flow, a variety of areas, more harmful substances in the air, stainless steel tube surface is very susceptible to environmental pollution, long time in this state of stainless steel tubing is very likely to appear small rust points. If the steel pipe stainless steel environmental pollution is light can be used in a way, if heavier can be used stainless steel rust removal paste cleaning, heavier is proposed to consult is not necessary to dismantle and replace.

5, due to more salt in the air at the beach is also easy to cause stainless steel pipe rust, it is recommended that the stainless steel pipe used on the beach should also be resistant to corrosion by chlorine, different application categories use different stainless steel pipe.

Finally, stainless steel water pipe manufacturers remind you, if it is not due to environmental factors caused by 304 stainless steel pipe rust, it is recommended to immediately to the installer or regional agents, stainless steel pipe manufacturers, etc. to understand the reasons, and deal with it immediately.
