Anti-rust treatment of expansion joints

Anti-rust treatment of expansion joints
Expansion joint is a kind of parts used to connect pipes or equipment, which can play a role in connecting different parts of pipes or equipment. At the same time, since expansion joints need to withstand large water pressure or air pressure, their materials must have high strength and high corrosion resistance to ensure their service life and safety.
 
However, in the process of use, expansion joints are easily oxidized and rusted, which will not only reduce their aesthetics, but also affect their service life and connection effect. Therefore, how to carry out anti-rust treatment becomes an important issue of concern for expansion joint manufacturers and users.
 
In order to solve this problem, expansion joint manufacturers have adopted various anti-rust treatment methods. The most common method is to use anti-corrosion paint or anti-corrosion coating. The advantage of this method is that it can effectively isolate oxygen and moisture and prevent oxidation and rusting of ferrous materials. At the same time, this method is easy to operate and less costly, so it is widely used.
 
In addition to paint and lacquer, there are some other methods of rust prevention. For example, metal surface treatment methods such as galvanizing and nickel plating are used, which can form a protective film on the surface to avoid rusting of joints. In addition, rust inhibitors can also be used for soaking and spraying to provide protection.
 
There are many ways to prevent rusting of expansion joints, and the choice of the method needs to be determined according to the specific situation. No matter what method is used, it is necessary to ensure its safety and effectiveness so as to better meet the needs of people.
