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
