Carbon Welded Steel Pipe Details

Carbon Welded Steel Pipe

Carbon welded steel pipe is a versatile and economical tubular product manufactured by forming and welding carbon steel strip or plate. Primarily produced through two main processes: ERW (Electric Resistance Welding) for high-frequency precision and SAW (Submerged Arc Welding) for large-diameter, heavy-wall applications.

Key characteristics include excellent strength-to-weight ratio, good weldability, and cost-effectiveness. Widely used in low/medium-pressure fluid transportation (water, oil, gas), structural applications (construction, fencing), and mechanical components. Its reliability and affordability make it a fundamental material in infrastructure and manufacturing sectors globally.
