Grade Selection Recommendations:

Grade A: Low budget, requires on-site bending and coiling, low-pressure short-term pipelines;

Grade B (preferred for 90% of overseas projects): Water supply and drainage, fire protection, buried pipelines, steel structure support, conventional pressure transmission, most versatile.

Core Product Advantages:

Significant Cost Advantage for Large Diameter Pipes:Ultra-large diameter pipes can be produced using narrow steel strips. Compared to seamless and straight-seam ERW pipes, large-diameter pipes offer lower procurement prices and shorter delivery times.

Welding-Friendly Processing:** With a moderate A53 carbon equivalent, there is no risk of cracking during on-site beveling, flange welding, and hot-dip galvanizing.

Stable Underground Operation:** Spiral oblique welds distribute soil pressure, reducing the risk of cracking and leakage due to uneven foundation settlement.

Comprehensive Corrosion Protection Solutions:** Customization is available for bare black pipes, hot-dip galvanizing, 3PE, epoxy coal tar, and FBE single-layer powder coatings to meet long-term underground burial requirements.
