Description
Carbon Steel ERW Pipes: Engineered for Superior Performance
Baoli Iron Steel proudly presents its premium range of Carbon Steel ERW Pipes, fabricated through a highly efficient Electric Resistance Welding (ERW) process. This advanced manufacturing technique involves cold or hot rolling steel coils into precise cylindrical forms, followed by welding along the longitudinal seam using high-frequency electric current. The result is a pipe renowned for its exceptional strength, reliability, and dimensional accuracy, making it an indispensable and cost-effective solution for a multitude of industrial and structural applications.
The ERW Manufacturing Excellence
Our ERW pipes are produced with meticulous attention to detail. The welding process creates a solid, high-integrity seam, often undergoing non-destructive testing (NDT) such as ultrasonic or eddy current inspection to ensure flawless performance. This commitment to quality in manufacturing guarantees a uniform wall thickness and a smooth external and internal surface, which is crucial for efficient fluid transport and structural integrity.
Key Features & Advantages:
- High Strength & Durability: Manufactured from robust carbon steel, our ERW pipes offer excellent tensile and yield strength, ensuring long-term performance under demanding conditions and high pressures.
- Cost-Effective Solution: The efficient ERW production method provides a more economical alternative compared to seamless pipes, especially for larger diameters and specific pressure ratings.
- Exceptional Dimensional Accuracy: Precise control during the welding and sizing stages results in consistent outer diameter, wall thickness, and impressive straightness.
- Versatility & Adaptability: Suitable for a wide spectrum of applications, from conveying various fluids to serving as critical structural components.
- Excellent Weldability & Formability: Easy to cut, bend, and weld on-site, facilitating faster and more efficient installation.
- Surface Treatment Options: Available in black (bare), varnished, anti-rust oiled, hot-dip galvanized, pre-galvanized, or various coated finishes (e.g., FBE, 3PE) to enhance corrosion resistance and extend lifespan.
Common Material Grades & International Standards:
Our Carbon Steel ERW Pipes are manufactured in strict adherence to leading international standards, ensuring top-tier quality and performance. Common grades and standards include:
- ASTM A53: Standard Specification for Pipe, Steel, Black and Hot-Dipped, Zinc-Coated, Welded and Seamless (Gr. A, Gr. B). Widely used for general purpose piping for steam, water, gas, and air.
