Why is there oil in the stainless steel pipe body?
Why is there oil in the stainless steel pipe body?

The problem of stamping on the surface of a stainless steel pipe: Take "as an example, we generally think that as long as the 304 stamp is stamped, it is a 304 stainless steel pipe. This is a relatively superficial understanding. In the deeper morning, there are two stainless steel pipes with the number 13 on them and then make a circle. What means ?

A few days ago, boss Wang, who was working on the construction site, called us to ask us, what does the number 13 mean? Does the stainless steel pipe contain only 13? This is also a more careful customer,-ordinary people rarely ask this kind of question , We told Boss Wang that 13 is the number of the workers who produced this batch of stainless steel pipes in the factory, which means that if there is a problem with this batch of pipes, the corresponding person will be found. After hearing this, Boss Wang felt that he was more responsible.

  1. What is the matter that there is a layer of oil on the surface of the stainless steel pipe?

Boss Wang, who is doing decoration, usually rarely touches stainless steel pipes. This time he renovated in his house and came to buy materials in person. After seeing the stainless steel pipes, he found that there was a layer of oil on the pipes. He asked me if it was a problem in the production process? I told him this. The oil does not affect the use. If you want to remove it, it is very simple. Simply wipe it out with a rag. On the contrary, this layer of oil plays a protective role to a certain extent.
