How To Extend The Life of Mild Steel Tube?

The service life of mild steel tube is usually between 20 and 30 years, and the specific service life depends on the use environment and maintenance.

‌

The service life of mild steel tube is affected by many factors, mainly including environmental conditions, usage, manufacturing process and maintenance:

1. Environmental conditions

‌Corrosive medium: Mild steel tube is easily corroded in corrosive medium, resulting in scaling of the inner wall of the pipe, thereby reducing the conveying capacity and service life. For example, when the pH value of the medium is low, the roughness of the pipe wall will increase, affecting the service life of the pipe.

‌Temperature and humidity: In high temperature and humid environment, the hardness and strength of steel will decrease, and it will be easily corroded, thus shortening the service life.

2. Usage

‌Load conditions: Under high load conditions, low carbon steel is prone to fatigue damage, thereby shortening the service life.

‌Maintenance: Regular inspection, repair and maintenance, such as timely treatment of corroded parts and replacement of damaged insulation layers, can effectively extend the service life of the pipeline.

3. Manufacturing process and maintenance

‌Manufacturing process‌: Different manufacturing processes will lead to differences in the internal structure and performance of low-carbon steel, which will in turn affect its service life‌.

‌Maintenance‌: Correct installation methods and good construction quality can ensure that the pipes are tightly connected, reduce leakage and stress concentration, and are conducive to extending the service life. ‌

‌The methods for extending the service life of mild steel tubes mainly include the following aspects‌: ‌

1. Anti-corrosion treatment‌

Mild steel tubes are susceptible to corrosion during use, so anti-corrosion treatment is the key to extending their service life. Anti-corrosion treatment can be achieved by coating the surface of the steel pipe with anti-corrosion coatings. These coatings have excellent chemical stability and corrosion resistance, and can resist the erosion of various corrosive media such as acids, alkalis, and salts. In addition, the anti-corrosion coating can also improve the wear resistance and durability of the steel pipe, reduce the wear and damage of the pipe, and thus extend its service life‌.

‌2. Regular maintenance and maintenance‌

Regularly check the status of the steel pipe, clean the dirt on the surface of the steel pipe in time, and avoid using highly corrosive solutions or sharp objects to scratch the surface. During the heating shutdown period, keep the steel pipe filled with water to prevent air from entering and causing corrosion. For the damaged parts, you can use special touch-up paint or nail polish to prevent the damaged parts from chemically reacting with oxygen and corroding.

‌3. Choose the right material

Ordinary low-carbon steel has poor corrosion resistance and is prone to water leakage. Therefore, you can choose materials with better corrosion resistance, such as the upgraded anti-corrosion diamond series products. These products are embedded with large alloy blocks containing magnesium, aluminum, zinc, chromium and other alloys on the basis of the normal three-layer anti-corrosion, which can absorb anti-corrosion ions in the water, protect the steel from corrosion, and greatly extend the service life of the steel pipe. ‌

Summary

In a general working environment, if properly maintained, the service life of mild steel tubes can reach 20 to 30 years. ‌ However, if the working environment is relatively harsh, such as the presence of strong corrosive media, high pressure fluctuations, etc., the service life may be shortened. ‌ Regular maintenance can effectively extend the service life of mild steel tubes, ensure their safe operation and reduce maintenance costs.
