Carbon steel pipes are one of the most preferred used materials in many industries that include construction, manufacturing, oil and gas among others. These pipes are available in many grades, sizes, and designs because their uses vary according to welded applications. In this blog post you will learn about the various types of carbon steel pipe that you can use in different sectors to meet your requirements.
What is Carbon Steel?
Carbon steel is a series of steels where carbon is the principal alloying element in excess of approximately 02 percent. It is widely used due to high strength, durability and comparably low price. Carbon steel pipe are produced from this material to suit a variety of uses. The classification for carbon steel pipe are low carbon steel pipes, medium carbon pipes, and high carbon pipes and each serves a specific need.
Types of Carbon Steel Pipes
Low Carbon Steel Pipes
Low-carbon steel has carbon content of less than 0.25% thus its ability to be drawn out and shaped easily. This makes it easy to weld, form and use while low-carbon steel pipe are the most extensively used pipes in the industries.
Uses of Low Carbon Steel Pipes:
- Water Supply Systems: The low-carbon steel pipe have mainly been used because they are easily workable in fabrication and corrosion resistance.
- Structural Applications: The following pipes are Structural Pipe, which are used extensively in construction of structures, supports for buildings and developments and overall infrastructure.
- Automotive and Aerospace: Due to their workability they are used to form parts used in automotive industries and aerospace industries.
Medium Carbon Steel Pipes
In medium carbon steel pipe the carbon range can vary between 0.25% and 0.60%. They allow the combination of high strength with reasonable ductility. Medium carbon steel is stronger than the Low carbon steel not as brittle as High carbon steel and is best suited to applications where stronger steel is needed but flexibility must not be completely compromised.
Uses of Medium Carbon Steel Pipes:
- Gas and Oil Pipelines: Because of their high strength and applications in pressure, these pipes are used in construction of gas and oil pipelines.
- Heavy Machinery: Medium carbon steel pipe are more suitable for constructing heavy and large machines and equipment subjected to a great degree of stress.
- Construction Projects: It is utilised in uses like support sections, frames as well as enhanced structures.
High Carbon Steel Pipes
High-carbon steel contains more than 0.60% carbon hence the hardest of the three types of steel. It is almost impossible for these pipes to break and they are well suited for regions where stress is placed on pipes. But they are also more likely to be brittle, this makes it less suitable for work where flexibility is required.
Uses of High Carbon Steel Pipes:
- Industrial Equipment: High carbon steel pipe are mainly applied in components of industrial machinery where there is significant wear and tear.
- Tool Manufacturing: These pipes are used in the manufacture of cutting tools and drill bits owing to its hardness and abrasive resistant.
- Construction: High carbon steel pipe are used in structures where high strength is necessary by applications like in bridges and highway structures.
The Use of Special Coatings in Carbon Steel Pipes
Carbon steel pipe are extremely robust and may be used in construction thus making they vulnerable to the corrosion especially when they come into contact with moisture and chemicals. Carbon steel pipe are known to be protected by specific layers in other to prolong their life span. The most common coatings include:
- Galvanized Coating: This finish is applied to the surface of the pipe to protect the pipes from rust and corrosion hence can be used outdoor and underground.
- Polyethylene Coating: A plating of plastic that provides more abrasion and chemical resistance in addition to the part.
- Fusion Bonded Epoxy: Own cobbing offers very good anti-corrosive properties and it can be used in high-pressure pipelines.
Why Choose Carbon Steel Pipes?
Carbon steel pipe are popular for several reasons:
- Cost-Effectiveness: Nonetheless, carbon steel pipe are cheaper compared to other metals like stainless steel, thus cheap for any project, especially if the project is large.
- Strength and Durability: Carbon steel pipe are valued for their significant working strength and therefore apply to high-pressure systems and application structures.
- Versatility: Carbon steel pipe have multifunctional applications in various types of working fluids such as water, oil, gas or structures and other materials.
Factors to Consider when using Carbon Steel Pipes
- Corrosion Resistance: As has been elucidated before, carbon steel is a material that rusts and corrodes easily. Application may require coatings or treatments and these are something that may be used.
- Temperature Sensitivity: High carbon steel pipe may show some level of treatment and therefore selection of material should involve consideration of temperature and stress factors.
- Weldability: Low carbon steel pipe and bends are easiest for welding but high carbon steel pipe are comparatively hard in nature and hence are difficult for welding.

Conclusion
Therefore, carbon steel pipe have low, medium, and high carbon content suitable for uses in construction, manufacture, or oil, and gas sectors. These pipes are characterized by great tensile strength, ranging costs, and splendid flexibility, thus freely applicable. The type of carbon steel pipe to select varies depending on the application of the pipe, its strength requirement, its resistance to corrosion and the specified working temperature.
