Carbon Steel Welded Pipes / Tubes
The properties of carbon steel are high hardness, strength, wear resistance and anti-corrosion.
Carbon steel is an alloy with carbon and iron, with carbon content up to 2.1% by weight. The increase in the carbon percentage will raise steel's hardness and strength, but it will be less ductile. Carbon steel has good properties in hardness and strength, and it is less expensive than other steels.

Application
Carbon steel welded pipe and tube are used in high-pressure conditions. They are highly resistant to shock and vibration, making it ideal to transport fluids. Carbon steel pipes are widely used in a number of industries, such as transporting water and sewage, oil and gas industries, boiler and condenser tubes, high-pressure applications, and chemical processing.
- Transporting water and sewage
- Oil and gas industries
- Boiler and condenser tubes
- High-pressure applications
- Chemical processing
