Poduct Introduction

Carbon Steel Welded Pipe is a versatile tubular product manufactured by bending and welding carbon steel plates or coils. Composed primarily of iron and carbon (typically 0.05%–0.30% carbon content), it offers a balance of strength, weldability, and cost-efficiency. The welding process, often Electric Resistance Welding (ERW) or Submerged Arc Welding (SAW), ensures structural integrity while enabling large-scale production.

Widely used in industries such as construction, oil/gas transmission, mechanical engineering, and infrastructure projects, it suits applications requiring moderate pressure and temperature resistance. Common grades include ASTM A53, ASTM A252, and API 5L, which define chemical compositions and mechanical properties. Its advantages include affordability, adaptability to various diameters/wall thicknesses via SCH ratings (e.g., SCH 40), and ease of fabrication. Surface treatments like galvanizing or coating enhance corrosion resistance for harsh environments. Compared to seamless pipes, welded variants provide comparable performance at lower costs, making them a preferred choice for non-critical high-pressure systems and general engineering purposes.
