Are you looking for a strong and reliable pipe material for your project? Carbon steel could be the perfect choice. This tough and versatile metal is great for many types of piping jobs. In this blog, we’ll explain what carbon steel pipes are, their key features. Carbon steel pipes, also known as CS pipes, are made from steel ingots or solid round bars. Read on to learn more about the benefits and uses of carbon steel pipes and why they might be right for you.
What are Carbon Steel Pipes?
Carbon steel pipe is made from iron and carbon, created by melting metals and shaping them into solid, cylindrical sections. It’s widely used in industries like oil and gas, plumbing, construction, energy pipelines, and automotive because it resists corrosion well.CS Pipe can handle temperature changes and different pressures, making them ideal for transporting fluids or gasses over long distances. CS pipes are crucial for modern infrastructure and can withstand tough conditions, making them essential for safe and reliable industrial operations.

Benefits of Using Carbon Steel Pipes
Carbon steel pipes offer many advantages over other materials. They are reliable and cost-effective, making them a great choice for various projects. CS Pipes’s durability reduces the need for frequent maintenance, as they can handle the wear and tear over time. They also don’t need special coatings or sealants to protect against weather like rain or snow, which simplifies installation and cuts down on maintenance costs. Additionally, CS Pipes are recyclable, so they can be used in future projects, supporting sustainable practices.

Properties of Carbon Steel Pipes
The main property of carbon steel pipes is their strength. They are very resistant to rust, making them great for different industries. CS pipes can handle high pressure and temperatures, so they’re effective for moving gases and liquids. There are different grades of carbon steel pipes for various uses. Low-carbon steel pipes are good for situations where you need strong resistance to stress cracking, while high-carbon steel pipes are better for applications needing extra strength and corrosion resistance.

The corrosion rate of carbon steel pipes is influenced by factors like the installation environment (indoor vs. outdoor), water quality, and ventilation. Generally, indoor pipes corrode slower than outdoor ones.
Density
Carbon steel pipes have a density ranging from 7.85 g/cm³ to 8.05 g/cm³, with higher grades being denser due to more alloying elements like manganese and chromium.
Standard Length
Carbon steel pipes typically come in standard lengths of 6 meters (19 feet) for seamless pipes and 12 meters (39 feet) for welded pipes, though custom lengths may be available.
Wall Thickness
Wall thicknesses for carbon steel pipes range from 0.13 inches to 4 inches. Thicker walls are used for heavy-duty applications, while thinner walls are suitable for lighter, residential uses.
Types of Carbon Steel Pipes
There are three main types of carbon steel pipes: carbon seamless steel pipe , ERW (electric resistance welding), and LSAW (longitudinal submerged arc welding). carbon seamless steel pipe is made from a solid steel bar by piercing it to form a hollow pipe, with no welds involved. ERW pipes are made by rolling metal into a tube and welding the seam to seal it. LSAW pipes are produced by bending and shaping a flat steel plate or coil into a pipe shape and then welding it. Each type is manufactured differently and serves various purposes depending on the requirements.

Carbon Steel Pipe Sizes and Thicknesses
Carbon steel pipes are available in a wide range of sizes and thicknesses, from 1/8 inch to 72 inches in diameter and from Schedule 10 to Schedule XXS in thickness. The size and thickness are chosen based on the specific application and the pressure the pipe needs to withstand.
Exploring Carbon Steel Pipe Production Methods
- Seamless Steel Pipes: Produced by hot rolling or cold drawing, these pipes are known for their high strength and tightness as they lack seams.
- Welded Steel Pipes: Made by rolling steel plates or strips into a cylindrical shape and then joining the seams through resistance welding or submerged arc welding.
