FAQ for Steel Supply Services
Why is spiral pipe preferred for large-diameter municipal water networks?
It allows for the production of extremely large-diameter pipes using relatively narrow steel coils, offering both cost-efficiency and high structural strength.
How do you verify the strength of the spiral weld seam?
We perform 100% automated Ultrasonic Testing (UT) across the entire seam, cross-checked with X-ray Radiographic Testing to ensure zero internal voids.
Do you provide anti-corrosion linings for drinking water pipelines?
Absolutely, we offer food-grade internal epoxy linings to ensure safety and hygiene for municipal drinking water networks.
Are your pipes suitable for heavy-duty coastal piling foundations?
Yes, our high-capacity spiral pipes are widely driven into the earth for port dock piling and bridge pier foundations due to their exceptional load-bearing stability.
Can you support large-volume energy transport project deadlines?
Yes, our continuous manufacturing lines are designed for high-efficiency production, ensuring your large-volume pipeline project stays on schedule.
