Which Is Cheaper, Carbon Steel Pipe Or Galvanized Steel Pipe?

There is still a certain difference between the prices of carbon steel pipe and galvanized pipe. According to the market price, in general, the price of carbon steel pipe is lower than that of galvanized pipe. Specifically, carbon steel pipes of the same specifications are about 10% to 20% cheaper than galvanized pipes.

Difference between carbon steel pipe and galvanized pipe

Carbon steel pipe is a steel pipe made by casting molten steel into billets in an oxygen-free furnace, and then cutting it into a certain length after multiple rolling forming. According to the carbon content, carbon steel pipes can be divided into three categories: mild steel pipe, medium carbon steel pipe and high carbon steel pipe. Carbon steel pipe has the advantages of high strength, wear resistance and plasticity, and its mechanical properties are also better than galvanized pipe.

Galvanized pipe is a steel pipe that is covered with a layer of zinc on the surface of ordinary black steel pipe after a series of treatment processes. Galvanized pipe not only has excellent corrosion resistance, but also beautiful appearance, and is also an important application field of picosecond laser imaging. However, since the main body of the galvanized pipe is still an ordinary steel pipe, its physical properties such as strength and pressure resistance are not as good as those of carbon steel pipe.

Price comparison

Compared with galvanized steel pipes, carbon steel pipes have lower manufacturing costs, so the price is more affordable. Under the same material and specifications, the price of carbon steel pipes can be 10%-20% lower than that of galvanized steel pipes.

Reasons for price differences

1. Galvanized pipes are coated with zinc on the outer layer, which increases production costs.

2. The surface of galvanized pipes is hot-dip galvanized, which is more corrosion-resistant and more beautiful than cold-dip galvanized surface, making its price relatively high.

3. Carbon steel pipes have a wider range of uses, large demand, relatively more production, and relatively lower prices.

Comparison of the advantages and disadvantages

1. Carbon steel pipes

The advantages of carbon steel pipes are high hardness, good wear resistance, and long service life. At the same time, carbon steel pipes have strong plasticity and weldability, and can be processed and interfaced according to needs.

The disadvantage is that carbon steel pipes are susceptible to corrosion and rust, and need to be treated with anti-corrosion treatment regularly, otherwise the service life of the pipe will be affected.

2. Galvanized pipes

The advantage of galvanized pipes is that they have good corrosion resistance and oxidation resistance, and are not easily corroded and rusted. In addition, galvanized pipes have the advantages of beautiful appearance and easy installation.

The disadvantage is that the galvanized layer will gradually peel off over time, affecting the service life of the pipe. In addition, during the manufacturing and processing of galvanized pipes, high-cost galvanizing processes and supporting equipment are required, and the cost is relatively high.

Selection guide

Galvanized steel pipes and carbon steel pipes each have their advantages and disadvantages. Which one is more suitable depends on the actual situation.

If you need a pipe with better corrosion resistance and wear resistance, and do not need mass production, you can choose galvanized steel pipes.

If you need a batch of pipes for large-scale production, the more cost-effective carbon steel pipe may be more suitable for your needs.

Use scenario

Because there is a certain price gap, not all occasions must use higher-priced galvanized pipes. Generally speaking, carbon steel pipes are suitable for conveying fluids in ordinary situations, while galvanized pipes are more suitable for scenarios that require corrosion protection and rust prevention, such as use in special environments such as coastal areas, coastal ports, and chemical companies.

Summary

To sum up, carbon steel pipes and galvanized pipes have their own characteristics and different usage scenarios, and there are certain reasons for the price difference. Generally speaking, the price of ordinary carbon steel pipes without special treatment is generally lower than that of galvanized steel pipes, but the specific needs to be combined with the material, specifications, etc. Comprehensive judgment, the choice of different pipeline materials needs to be selected according to specific usage requirements.
