Our electric resistance welding process begins with precision-cut steel strips formed into cylindrical shapes through cold-forming techniques. High-frequency electrical current creates molecular bonding at strip edges without filler metal addition. Post-welding normalization ensures uniform grain structure throughout the pipe wall. Each pipe undergoes dimensional inspection and hydrostatic testing before final quality approval.

Q: Is your Schedule 40 ERW pipe suitable for fire sprinkler systems?
A: Yes, our A53 Grade B ERW pipes are strictly manufactured and tested for fire protection applications, offering excellent pressure resistance and easy threading for field installation.
Q: How do you guarantee the strength of the weld seam?
A: Each pipe undergoes High-Frequency Induction Welding followed by full-length seam annealing. This ensures the metallurgical structure of the weld matches the base metal, backed by 100% hydrostatic testing.
Q: What's the difference between ERW and seamless pipes?
A: ERW pipes offer tighter wall thickness tolerances and lower costs for moderate pressure applications, while maintaining comparable strength properties.
Q: Can you provide material test certificates?
A: Yes, we provide Mill Test Certificates (MTC) with complete chemical composition and mechanical property documentation for every shipment.
Q: What's your minimum order quantity?
A: Our MOQ varies by size and specification, typically starting at 10 tons for standard sizes with flexible terms for ongoing projects.
Q: Do you offer threading services?
A: Yes, we provide precision threading, beveling, and end preparation services to deliver ready-to-install pipes.
