Product Overview

Our ERW (Electric Resistance Welded) Steel Pipe offers an economical and reliable solution for general structural, construction, and mechanical applications. Manufactured using high-frequency electric resistance welding technology, these pipes combine cost-effectiveness with consistent quality, making them the go-to choice for projects where seamless pipe specifications are not mandatory. With an annual production capacity of 10,000 tons, we deliver ERW pipes that meet the highest standards of dimensional accuracy and structural integrity.

Key Features & Advantages

• Cost-Effective Solution: ERW manufacturing process significantly reduces production costs compared to seamless pipes while maintaining excellent structural performance, with savings of 20-30% on material costs for general applications.
• High-Frequency Welding Technology: Advanced HF welding with post-weld heat treatment (normalizing) ensures uniform metallographic structure across the weld zone, heat-affected zone, and base material for consistent mechanical properties.
• Superior Surface Quality: Smooth, scale-free surface finish ideal for painting, galvanizing, powder coating, or direct use in visible structural applications.
• Precision Dimensions: Tight OD and WT tolerances with excellent straightness, reducing fit-up time and fabrication costs on construction sites.
• Wide Standards Compliance: Available to ASTM A53, ASTM A500, EN 10219, JIS G3444, and GB/T 3091 standards, catering to global market requirements.
