1. Application of carbon steel tube in desalinated water treatment

Desalinated water treatment is one of the essential processes in modern production, and various pipes have emerged as the times require. Carbon steel tubee, as a common industrial building material, is also considered for use in desalinated water treatment. However, whether its applicability is reliable requires detailed analysis.

The most notable features of carbon steel tubes are cheap, easy to process, and high strength. This allows it to be used in demineralized water under certain conditions. However, in practical applications, due to the high salt content in desalted water, carbon steel pipes are easily corroded, resulting in a series of problems such as corrosion, wear, cracking, and deformation of the pipe wall. This will not only reduce the service life of carbon steel tubes, but also have a great impact on the performance of the entire process system.

2. Advantages and disadvantages of carbon steel tube

Carbon steel tubes are used as pipes for desalinated water treatment, and their advantages and disadvantages are as follows:

Advantages: low price, easy processing, high strength, can withstand certain pressure, high temperature resistance, wide application range.
Disadvantages: easy to be corroded by salt water, causing problems such as corrosion, wear, cracking, and deformation of the pipe wall; the service life is greatly reduced; it cannot withstand extremely high pressure and high temperature environments.

3. Suggestions for other pipe selection

In view of the shortcomings of carbon steel pipes, it is recommended to choose stainless steel or fiberglass pipes that are resistant to corrosion, oxidation, high temperature and low temperature. These pipes can better withstand the corrosion of salt in desalinated water and other chemicals without the problems of carbon steel tubes. At the same time, these materials are also stronger and can last longer.

In short, there are certain risks and limitations in the application of carbon steel tubes in desalinated water treatment. In specific applications, it is necessary to conduct detailed analysis according to process requirements and actual conditions to select suitable pipes.

Tips: Carbon steel welded pipes can be divided into three types: straight seam submerged arc welded steel pipes, spiral welded pipes, and high-frequency straight seam welded steel pipes (Electric Resistance Welded Steel Pipe) according to the forming method of the weld seam.
