Difference Between Carbon Steel And Galvanized Steel Pipe:

1. Material Composition

Both carbon steel and galvanized steel are made of iron plus carbon, however, carbon steel has a total alloy content of less than 2%, while galvanized steel has a total alloy content of 10-30%. Additionally, galvanized steel has a zinc coating that protects it from corrosion. In contrast, carbon steel does not have this protection and therefore corrodes more quickly when exposed to environmental elements without proper protection.

2. Manufacturing Process

Carbon steel pipe is made by piercing steel ingots or solid round steel to form capillaries, and then hot rolling, cold rolling, and cold drawing. Carbon steel pipe occupies an important position in the domestic steel pipe field. Galvanized steel pipe is hot-dip galvanized. Galvanized steel pipe should be tested for the balance of the galvanized layer.

3. Properties

Carbon steel is stronger than galvanized steel. However, the galvanized layer makes galvanized steel more resistant to corrosion.

4. Applications

Carbon steel pipe is suitable for bridges, buildings and automobile industries to withstand high pressure; while galvanized steel pipe is mainly used in wet and corrosive places, such as petrochemical, chemical, shipbuilding and marine development.

To sum up, the difference between carbon steel pipe and galvanized steel pipe lies in material composition, manufacturing process, properties and applications. When choosing a pipeline, you need to consider the specific usage scenario and the required performance characteristics. Knowing these differences will help you make sure you buy the right pipe for your needs!
