ASTM A53 B, ASTM A106 Gr. B, ASTM A179, ASTM A192, ASTM A333 and API 5L Gr B to X70 Carbon steel seamless pipe is a widely used metallic tubing composed primarily of carbon and iron, characterized by its elongated cylindrical shape and hollow cross-section. It serves as a critical conduit for fluid transmission (e.g., petroleum, natural gas, coal gas, water) and is also extensively employed in structural and mechanical components.
Key Applications:
Fluid transport: Oil/gas pipelines, high-pressure water systems.
Mechanical parts: Oil drill pipes, automotive drive shafts, bicycle frames.
Construction: Steel scaffolding for building projects.
