Marzouk Steel is a trusted manufacturer and supplier of Carbon Steel ERW Pipes in Tunis, Tunisia, delivering reliable piping solutions for construction and industrial applications. ERW (Electric Resistance Welded) pipes are known for their uniform wall thickness, smooth finish, and cost-effective performance. At Marzouk Steel, our ERW pipes are manufactured using high-quality carbon steel and advanced welding technology to ensure strong weld seams and consistent dimensions. With a focus on quality, safety, and timely delivery, we supply ERW pipes that meet international standards and perform reliably in everyday operations.
Carbon Steel ERW Pipes are made from low to medium carbon steel with controlled amounts of manganese and other elements to enhance strength and toughness. The electric resistance welding process creates a strong, continuous weld joint. Mechanically, these pipes offer good tensile strength, excellent pressure-handling capability, and reliable dimensional accuracy. They also provide good weldability and formability, making them suitable for fabrication and installation across a wide range of industrial and structural applications.
