ERW tubes, or Electric Resistance Welded tubes, are a type of steel tubing produced through a high-frequency welding process. These tubes are widely used in various industries due to their strength, durability, and cost-effectiveness. The manufacturing process involves passing a steel strip through a series of rollers, where it is formed into a cylindrical shape, and then welded longitudinally using electric resistance. This welding process ensures that the tube has a strong, uniform seam, making it suitable for a wide range of applications. Key Features: Material Composition: ERW tubes are typically made from mild steel, stainless steel, or galvanized steel, offering various grades to meet different strength and corrosion resistance requirements. Manufacturing Process: The process of electric resistance welding uses heat generated by electrical resistance to bond the edges of the steel strip, creating a continuous tube. This process results in a smooth, clean weld seam that is often stronger than the base material itself. Variety of Sizes: ERW tubes are available in a wide range of diameters and wall thicknesses. They can be customized to meet the specific requirements of industries like automotive, construction, and oil & gas. Surface Finish: ERW tubes come with various surface finishes, such as mill finish, galvanized, or powder-coated, providing options for aesthetic appeal and enhanced corrosion resistance. Strength and Durability: The ERW process ensures uniformity in strength and structural integrity, making the tubes ideal for high-pressure applications. The welded seam is highly resistant to cracking and fatigue. Cost-Effectiveness: Compared to other types of welded or seamless tubes, ERW tubes are more affordable due to the efficient manufacturing process. Applications: Automotive Industry: Used in exhaust systems, chassis, and structural components. Construction: Employed in structural frameworks, scaffolding, and fencing. Oil & Gas: Ideal for pipelines, drill pipes, and other high-pressure applications. Furniture Manufacturing: Used in the production of furniture frames and other industrial products. Mechanical Engineering: Applied in various mechanical and hydraulic systems. Benefits: Precision and Consistency: The ERW process ensures that each tube is uniform in size and quality, minimizing defects. Flexibility: Customization options for length, diameter, and wall thickness to suit specific needs. Environmental Benefits: ERW tubes are recyclable, contributing to sustainability efforts in manufacturing. Conclusion: ERW tubes are a versatile and reliable choice for a variety of applications across different industries. Their high strength, cost-effectiveness, and customization options make them an excellent solution for projects requiring durable and high-quality steel tubing.

Product Description Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate. Production process: Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc. Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance.
