1、 Why do stainless steel water pipes rust
Stainless steel has the ability to resist "large" oxidation - that is, rust resistance. At the same time, it also has the ability to corrode in media containing acid and alkali salts - printing resistance. However, if the corrosion-resistant pure water contains impurities, it will affect the experimental results. Therefore, the pure water produced by the pure water equipment needs to be used in a timely manner and cannot be stored for a long time.
The size of the ability star depends on the chemical composition of the steel itself and the interaction state. Changed due to usage conditions and environmental medium type. Why do stainless steel pipes rust in dry and clean environments like 1304 stainless steel pipes? Stainless steel has the ability to resist large oxidation - that is, stainless steel. At the same time, it also has the ability to corrode in media containing acid and alkali salts - printing resistance. But the magnitude of its corrosion resistance depends on the chemical composition of the steel itself and its interaction state. Changed due to usage conditions and environmental medium type. For example, 1304 stainless steel water pipes have absolutely excellent corrosion resistance in dry and clear air, but when moved to coastal areas, they will quickly rust in sea fog containing a large amount of salt, while 316 steel pipes perform well.
Therefore. Not any type of stainless steel. It can be corroded and rust free in any environment. Stainless steel relies on a thin, strong, and stable chromium rich oxide film (protective film) formed on its surface to prevent further infiltration and oxidation of oxygen atoms, thus obtaining the ability to resist corrosion- If for some reason, this thin film is constantly damaged, oxygen atoms in air or liquid will continuously infiltrate, or iron atoms in metal will continuously separate, forming loose iron oxide. Jin Yan's appearance has also been constantly eroded.
2、 How to remove rust from rusted copper water pipes
Stainless steel water pipe descaling can be divided into physical rust removal and chemical rust removal- Stainless steel pipes usually rust, and most of them are treated with tools to remove the oxide. For example, using tools such as wire brushes to polish the surface of the cookware can remove loose or tangled oxide scales, rust, welding slag, and even pipes that have been drawn. We can use a wire drawing ball to polish the surface of the pot material on rusted parts, which can remove loose or tangled oxide scales, rust, welding slag, and other materials, as well as pipes after wire drawing. We can manually re draw the rusted area with a drawing ball. It can also achieve the purpose of rust removal.
The chemical land pot method uses both chemical and electrolytic methods for acid washing treatment. By using chemical acid washing, oxidation scale and rust can be removed. Old elimination. The principle is to use acid washing solution to react chemically with the oxide on the surface of the pipe, thereby achieving the effect of rust removal.
3、 What should I do if the stainless steel water pipe rusts and cannot be unscrewed
1. Change to a larger pipe for Sweet Field, and if there is no work available, find a longer pipe to connect to the handle. Growth power stomach! As long as it loosens, everything will be fine.
2. Take a small willow head and gently tap the tube, tapping multiple places, then twist it again.
3. Kerosene, gasoline, engine oil, and milk remover, you can choose to apply them to dead areas. Operate later.
4. In case of urgent disassembly, flush the metal water pipe connector with Baijiu or alcohol. Wait a minute. Use Xiao Li Zhen Zhen to send it off, but it's a bit laborious.
5. If it is not like dismantling, use engine oil, rotten oil, diesel, edible oil, etc. to apply a few drops of wine to the rusted area of the metal water pipe interface. Depending on the size and degree of rust of the pipe fittings, it can be easily disassembled after 10 to 24 hours. In addition, waterproof tape should be wrapped around the outer thread of the stainless steel water pipe and connected to the matching thread. Tighten the well, then wrap the outer thread of the stainless steel water pipe with waterproof tape and apply the second pair of threads.
6. Apply waterproof tape to the outer thread of the faucet and apply it to the other end of the thread. Open the water gate. Test if there is any leakage, if not, then it can be used.
