We all know that the stainless steel black oxide layer on the surface of the stainless steel pipe after high-temperature solution treatment. If you want to remove the oxide layer, pickling is an important procedure. What's more, if the surface of stainless steel pipe is dirty, passivation is needed. Here is the stainless steel seamless pipe introduction related to pickling and passivation.
Then what is pickling? Pickling refers to putting the stainless steel seamless pipe or pipe fittings soaking in the 10-15% nitric acid or 5-8% hydrofluoric acid. Pickling process is expensive to start with nitrate chromium oxide-oxide to chromium oxide objects. Then hydrofluoric acid will dissolve the high-valence oxide in acid solution. Pickling will get rid of this oxide coating and the weight of steel pipe or fittings reduced. Usually after pickling, we should do the passivation to form a passivation film to protect the pipe or fittings not to be oxidized, thereby improving steel tube or pipe corrosion resistance.
Therefore, we can say the pickling is very important to the production process of stainless steel tube. Then what about passivation? It is the same important as the pickling process. Passivation is to form a passivation film on the surface of the stainless steel tube so that the corrosion resistance of the pipe can be high and the service life can be long.
When doing the stainless steel seamless pipe introduction, what cannot be ignored is that wide application of stainless steel pipe. In modern society, stainless steel seamless pipe is almost everywhere. In our house, you can see the window and door frame is usually made of stainless steel pipe. In many buildings, you can see the structure is usually set up with stainless steel pipe because stainless steel tube has high strength and corrosion resistance.
Although stainless steel seamless pipe has a lot of advantages, there is a precondition. Only the high-quality stainless steel pipe has advantages mentioned in the stainless steel seamless pipe introduction above. Maybe there are a lot of companies manufacturing stainless steel pipe can provide the lowest price for you. However, they cannot promise that their products are the best. However, Shangshang can. Shangshang is definitely one of the best suppliers of stainless steel seamless pipe in China. Shangshang is not only famous in China, but also many other countries know the name of Shangshang, from which we can see the brand influence of Shangshang.
