Tianjin Yuantai Derun wholesale erw black round steel welded pipe Manufacturer

Product Overview

•Definition: ERW (electric resistance welding) steel pipe adopts high-frequency current welding process, suitable for low-pressure fluid transportation, building structure and other fields.

•Features: high weld strength, high production efficiency, low cost, smooth surface without burrs.

Erw Tube Manufacturing Process

Yuantai's products

Precision high-frequency resistance welding process

Adopting high-frequency welding equipment imported from Germany, the weld is uniform and free of oxides, and passes 100% online ultrasonic testing.

Ultra-wide size coverage capability

Outer diameter 21.3-1220mm, wall thickness 1.0-25mm (industry leading), support non-standard customization (such as special-shaped sections).

High-strength material system

Core material: Q355B (national standard), API 5L X42-X60 (American standard), tensile strength ≥520MPa (10% higher than the industry).

Intelligent anti-corrosion technology

Optional hot-dip galvanizing (zinc layer ≥85μm), 3PE coating (acid and alkali resistant), nano-epoxy paint (-30℃ weather resistant).

Yuantai's Differentiated Advantages

1. Process advantages

Yuantai Derun's exclusive "dual-frequency welding" technology, the weld strength reaches 95% of the parent material, eliminating the defect of unfused.

2. Delivery efficiency

Regular orders are delivered in 15 days (the industry average is 25 days), and urgent orders support 72-hour expedited production (requires +8% fee).

3. Cost control

Scaled production + self-developed raw material ratio, the price of the same specification is 5%-8% lower than the market.

4. Green certification

Complies with the EU RoHS environmental protection standards and provides carbon footprint reports (in line with the ESG needs of overseas customers).
