Carbon Steel Seamless Pipe
Carbon steel seamless pipe is a weldless steel pipe made from carbon steel using a specific process.
Composition and Classification

- Composition: Primarily composed of iron (Fe) and carbon (C), it also contains small amounts of silicon (Si), manganese (Mn), phosphorus (P), and sulfur (S). Carbon is a key element in determining the properties of carbon steel. As the carbon content increases, the steel's strength and hardness increase, while its plasticity and toughness decrease.

- Classification: Based on the carbon content, carbon steel seamless pipe can be divided into the following categories:

- Low Carbon Steel Seamless Pipe: The carbon content is generally less than 0.25%. This type of steel pipe has good plasticity and weldability, but relatively low strength. It is often used to manufacture structural components or pipelines that require less strength but higher plasticity and weldability, such as pipes for transporting low-pressure fluids such as water and gas.

- Medium Carbon Steel Seamless Pipe: The carbon content ranges from 0.25% to 0.60%. It has excellent overall mechanical properties, combining strength and hardness with a certain degree of plasticity and toughness. It is often used in the manufacture of mechanical parts such as shafts and gears, which must withstand certain loads and wear.

- High Carbon Steel Seamless Pipe: Carbon content greater than 0.60%. This type of steel pipe has high strength and hardness, but poor plasticity and toughness. It is primarily used in the manufacture of components requiring high wear resistance and strength, such as springs and tools. However, due to its poor weldability, its application in welded structures is relatively limited.

Seamless steel pipes are made by punching holes through a whole round steel bar. Steel pipes with no weld seams on the surface are called seamless steel pipes. Based on the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, precision seamless steel pipes, and extruded seamless steel pipes. The maximum diameter is 900mm, and the minimum diameter is 4mm. Depending on the application, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. They are mainly used in oil geological drilling pipes, cracking pipes for petrochemicals, boiler pipes, bearing pipes, and high-precision structural pipes for automobiles and aviation.
