Benefits & Insufficiency of Galvanized Mild Steel Pipe‌

Galvanized mild steel pipe refers to steel pipes with a layer of zinc on the surface of mild steel pipes. Galvanized mild steel pipes combine the processing performance of mild steel pipes and the anti-corrosion performance of the galvanized layer. They are suitable for a variety of industrial and civil fields and have broad application prospects.

Galvanized mild steel pipes have the following characteristics:

1. Mild steel pipes: Mild steel pipes have a carbon content of less than 0.25%, commonly known as mild steel. Due to their low carbon content, mild steel pipes have lower strength and hardness, but are easy to process and weld, and are often used in engineering structural parts and mechanical parts that require wear resistance.

2. Galvanizing: Galvanizing is to coat the surface of mild steel pipes with a layer of zinc to prevent oxidation and corrosion of the steel surface. The galvanized layer can make the surface of the steel pipe smooth and beautiful, and improve its anti-corrosion performance. Galvanized steel pipes are widely used in construction, home appliances, automobiles, ships and other fields.

‌3. Production process‌: The production process of galvanized mild steel pipes includes drawing, pickling and rust removal, high-temperature annealing, hot-dip galvanizing and cooling. These processes ensure the surface quality and anti-corrosion performance of the steel pipe.

The benefits of galvanized mild steel pipes mainly include the following aspects:

1. Corrosion resistance

Due to the protection of the zinc layer, galvanized mild steel pipes can resist corrosion from media such as the atmosphere and water. In a neutral or weakly acidic environment, the turbid products formed after zinc corrosion are insoluble compounds. These products form a dense thin layer with strong adhesion, which can effectively isolate the atmosphere and galvanized sheets to prevent further corrosion.

‌2. High structural strength

The galvanized mild steel pipe has a stable structure, good compression and impact resistance, is not easy to deform, and has a high safety guarantee. Its surface is smooth, the color is uniform, and the texture is good, which is suitable for indoor and outdoor decoration.

3. ‌Long service life‌

There is a layer of zinc on the surface of the galvanized mild steel pipe, which prevents the steel pipe from corrosion and rust, so it has a longer service life. Compared with ordinary steel pipes, galvanized steel pipes have lower maintenance and replacement costs.

‌4. Economical

The cost of galvanized mild steel pipes is relatively low, and the price is more economical compared with other steel pipes such as stainless steel pipes. Its wide range of applications includes construction, furniture, transportation and agriculture, which further reduces the overall cost.

5. Environmental protection

The surface of galvanized mild steel pipes is treated with varnish or plastic spraying to prevent rust and corrosion on the surface of the steel pipe. Compared with traditional spray painting, galvanized steel pipes are not easy to fall off, and their oxide layer is formed naturally, which will not pollute the environment. ‌

The main shortcomings of galvanized mild steel pipes include the following aspects:

‌1. Poor high temperature resistance

Compared with pipes made of some special materials, such as ceramic pipes, glass pipes, etc., galvanized mild steel pipes have poor performance in high temperature environments. Under high temperature conditions, galvanized mild steel pipes may have problems such as deformation and oxidation.

‌2. High cost

The production process of galvanized mild steel pipes is complicated and the cost is relatively high, which makes them more expensive.

‌3. Susceptible to scratches

The zinc layer on the surface of galvanized mild steel pipes is relatively thin and easily scratched. Once the zinc layer is damaged, it is easy to cause rust‌.

‌4. Welding seam problems

During use, the weld may have "oblique defects", and attention should be paid to the direction of the principal stress‌.

Summary

Galvanized mild steel pipes are widely used in construction, furniture, transportation, agriculture and other fields due to their strong anti-corrosion performance, corrosion resistance, high structural strength, long service life, economy and environmental protection. At the same time, special attention should be paid to the shortcomings of galvanized mild steel pipes during use to ensure their stability and safety during use.
