What are Carbon Steel Tubes?
Carbon Steel Tubes are hollow, cylindrical steel products manufactured using carbon-rich steel alloys. Depending on the production method, tubes are categorized as seamless or welded.
Seamless carbon steel tubes are preferred for high-pressure and high-temperature applications due to their strength and uniform structure, while welded tubes offer cost advantages for general structural uses.
Carbon steel tubes provide a perfect balance between affordability, machinability, and mechanical strength, making them an essential material for fluid transport, mechanical systems, and structural supports.
