There are significant differences between carbon steel pipes and galvanized pipes in many aspects. The following are their main differences:

1. Production process

Carbon steel pipe: Steel ingots or solid round steel are perforated to form capillary tubes, which are then hot-rolled, cold-rolled or cold-drawn. This process enables carbon steel pipes to occupy an important position in my country's steel pipe industry.

Galvanized pipe: mainly produced by hot dip galvanizing method. In this process, the steel pipe will first be pickled to remove iron oxide on the surface, and then immersed in molten zinc liquid to combine the zinc with the surface of the steel pipe to form a zinc layer.

2. Materials used

Carbon steel pipe: Use high-quality carbon structural steels such as 10, 20, 30, and 45, as well as low-alloy structural steels such as 16Mn and 5MnV or alloy steels such as 40Cr, 30CrMnSi, 45Mn2, and 40MnB as raw materials.

Galvanized pipe: Its raw material is various base steel pipes. The galvanizing treatment is achieved by immersing the steel pipe in molten zinc liquid, thereby forming a zinc layer on the surface of the steel pipe.

3. Technical performance and characteristics

Carbon steel pipe:

It has high strength and hardness and is suitable for withstanding large pressure and load.

Seamless pipes are mainly used for fluid transportation pipelines, such as stressed parts of automobiles and tractors.

Hot-rolled steel pipes are delivered in a hot-rolled or heat-treated state, and cold-rolled steel pipes are delivered in a heat-treated state.

Galvanized pipe:

It has excellent anti-corrosion properties. The existence of the zinc layer isolates the steel pipe from contact with the outside world and prevents oxidation and corrosion of the steel pipe.

It has good durability and can maintain its original performance and appearance even under harsh environmental conditions.

The texture is hard, not easy to wear, the surface is smooth, and not easy to accumulate dirt.

4. Application areas

Carbon steel pipe: widely used in machinery manufacturing, aerospace and other fields. Due to its high strength and hardness, it is especially suitable for manufacturing mechanical parts that need to withstand large pressure and load.

Galvanized pipe: Due to its excellent anti-corrosion performance and durability, it is widely used in construction, municipal administration, industry, electric power, petroleum and other fields. For example, in the construction field, galvanized pipes are used in pipeline systems such as water supply, drainage, and heating; in the municipal field, they are used in pipeline systems such as sewage, rainwater, and tap water; in the industrial field, they are used in petroleum, chemicals, electricity, and other industries fluid transport pipelines.

5. Cost and price

Generally speaking, since galvanized pipes require additional galvanizing processes, their production costs are relatively high, so the market price is usually higher than carbon steel pipes of the same specifications.

To sum up, there are obvious differences between carbon steel pipes and galvanized pipes in terms of production process, materials used, technical performance, application fields, cost and price. Which steel pipe to choose depends on the specific usage scenarios and needs.
