Carbon steel pipe:properties, types and applications
Carbon steel pipe, with its excellent mechanical properties, corrosion resistance and processing performance, is widely used in many fields. This article will introduce the properties, types and applications of carbon steel pipe in detail.
Characteristics of carbon steel pipe
1. Mechanical properties:
Carbon steel pipe has high strength and toughness, and can withstand greater pressure and vibration. In addition, its good ductility and plasticity make carbon steel pipe easy to process and weld.
2.Corrosion resistance:
Carbon steel pipe has good corrosion resistance to a variety of acids, alkalis, salts and other chemical media, and can effectively resist a variety of corrosive environments.
3. Wear resistance:
Carbon steel pipe has high hardness and good abrasion resistance, which is suitable for occasions of serious wear and tear.
4. Economy:
The price of carbon steel pipe is relatively low, and the installation and maintenance costs are also more reasonable, with good economy.
| Characteristic | Description | Value |
|---|---|---|
| Mechanical Properties | Tensile strength | 370-550 MPa |
| Yield strength | 240-370 MPa | |
| Elongation | 20-40% | |
| Corrosion Resistance | Corrosion resistance rating | Moderate corrosion resistance |
| Corrosion resistance in various environments | Acids, alkalis, salts and other chemical media | |
| Abrasion Resistance | Hardness range | HRC 20-45 |
| Economy | Price relative to other metal pipes | Low cost |
| Installation and maintenance costs | Low cost |
Types of carbon steel pipe
1.Classification according to manufacturing process:
Carbon steel pipe can be divided into seamless steel pipe and welded steel pipe. Seamless steel pipe is manufactured by hot rolling or cold drawing process, which has high strength and corrosion resistance; welded steel pipe is manufactured by welding process, which has the advantages of low cost and high production efficiency.
2. Categorized by use:
Carbon steel pipe can be divided into steel pipe for fluid transportation, structural steel pipe, boiler steel pipe, steel pipe for oil cracking, etc.. Different types of steel pipe have different uses and performance requirements.
| Grade/Model | Chemical composition | Main uses |
|---|---|---|
| Q195 | Low carbon | Construction, bridges, petroleum, chemicals, machinery manufacturing and other fields |
| Q235 | Normal carbon structural steel | Construction, petroleum, chemicals, electricity, aerospace and other fields |
| Q345 | High strength low alloy structural steel | Bridges, construction, petroleum, chemicals, electricity and other fields |
| 20# | Carbon structural steel | Machinery manufacturing, automobile manufacturing, shipbuilding and other fields |
| 45# | High carbon structural steel | Machinery manufacturing, automobile manufacturing, mold manufacturing and other fields |
| 16Mn | Low alloy high strength structural steel | Petroleum, chemicals, electricity, aerospace and other fields |
| Q235B | High quality carbon structural steel | General structure and machinery manufacturing fields, steel plate, welded pipe and other product manufacturing |
| 20# steel pipe | High carbon structural steel | High pressure gas bottles, hydraulic cylinders, automotive brake systems and other product manufacturing, oil and gas pipelines and other fields |
| 45# steel pipe | High carbon structural steel | Heavy machinery manufacturing, automobile manufacturing, oil and gas pipelines and other fields, forgings, machine tool guideways, mechanical gears and other product manufacturing |
| 16Mn steel pipe | Low alloy high strength structural steel | Low temperature and high pressure pipelines, construction structures, bridges and other fields, pipelines for the transportation of petroleum, natural gas and chemicals in the petroleum, natural gas, chemicals and other industries. |
Application of carbon steel pipe
