Steel pipe such as hot dipped galvanized steel pipe is relatively common in our life, which is quite good in our daily life, production as well as processing. Besides its service life is also quite long compared with other common steel pipes. Nowadays, steel tube material is various and hot galvanizing steel tube has become more good pipe material. Actually, the specification of galvanized steel pipe is multiple and its processing technology is multifarious, so its quality ranks the top. However, a lot of friends find that square tube will be rusty in the application process. So what is the cause of the steel tube rusting? How to remove rust effectively?
The anti-corrosion performance of galvanized steel pipe is relatively good. However, if you do not pay attention to the application environment, the pipe will still be rusted for a period of time. What are the problems in the foreign trade of galvanized steel pipe? Of course, it is very important to prevent rust. In order to ensure the efficiency of hot-dip galvanized steel pipes, we should pay attention to the relevant operational matters as well as operating environment. If there is rusty on pipe surface, the pipe will produce some white powder substance on the surface. This kind of material refers to zinc oxide which is also called while rust and the reasons mainly include the following:1.hot dip galvanized steel pipe coating does not operated according to the standard in the production process which lead to a weak coating.2. the rust of the pipe surface can not be removed during acid cleaning.
Exposure to the external environment in the long run will also deepen the rust of the steel tube like round steel pipe. So how to remove rusty? In the application process of hot-dip galvanized steel pipes, there is no worry about the rusty because of zinc layer which can not be completely eroded and there is a certain protective effect on the steel pipe inside. Using acidic or alkaline liquid to clean the pipe will damage the steel pipe, instead of sand paper or steel wire ball so as to guarantee the life service. As its extensive application scope, steel pipe manufacturers should make some adjustments according to different circumstances. What are the downstream industries of galvanized steel pipes？Except for the strictly control in the process of production, we also need to make comprehensive consideration in terms of situation.
