Carbon Steel Pipes Q345B/Q195/Q215
Materials
Carbon steel material: Carbon steel pipes are usually divided into low carbon steel, medium carbon steel and high carbon steel according to the carbon content. Common materials include:
Q195: Low carbon steel, suitable for general purpose.
Q235: Medium carbon steel, widely used in buildings and structures.
Q345: High-strength low-alloy steel, suitable for applications with high load-bearing requirements.
Specifications
Diameter: The outer diameter of carbon steel pipe is usually between 10mm and 1000mm, and the specific diameter can be customized according to requirements.
Wall thickness: The wall thickness is usually between 1mm and 20mm, and the specific thickness can be provided according to customer needs.
Length: Carbon steel pipes are usually provided in cut-to-length or coil form, and the length can be customized according to customer needs.
Production process
Hot Rolling or Cold Rolling Process: Carbon Steel Pipes can be produced by either hot rolling or cold rolling process.
Hot rolling process: suitable for pipes with larger diameter and thickness, with better plasticity and toughness.
Cold rolling process: Suitable for tubes requiring higher precision and surface finish.
Surface treatment
Surface finish: The surface of carbon steel pipes is usually rough, which is suitable for subsequent processing.
Rust-proof treatment: Anti-rust treatment such as oiling or galvanizing can be performed as required to improve corrosion resistance.
Advantages
High Strength: Carbon steel pipes have good strength and toughness, suitable for bearing greater pressure and load.
Affordability: Relatively low cost makes it an affordable choice.
Good processability: Carbon steel pipes are easy to cut, weld and form, suitable for various manufacturing processes.
Application Areas
Construction Industry: For structural support, pipes and framing.
Oil and Gas Industry: Used to transport oil, natural gas and other fluids.
Chemical Industry: used for transportation and storage of chemicals.
Manufacturing Industry: Used in machinery and other industrial applications.
Maintenance
Regular Inspection: It is recommended to regularly inspect the surface of carbon steel pipes to ensure there is no rust and damage.
CLEAN: Keep the surface clean to avoid accumulation of dirt and chemicals.
