Performance features.

1. Thicker wall thickness, greater strength: resistance to deformation, impact, and settling; less prone to being compressed when buried.

2. High pressure tolerance: Can withstand working pressures of 2.5–4.0 MPa, suitable for high-pressure water supply, firefighting, and chemical process circulation systems.

3. Long-lasting corrosion resistance: The hot-dip galvanized coating protects against moisture and soil, making it suitable for outdoor/subterranean use for 20 to 35 years.

4. Excellent structural rigidity: can be used for pipe piles, columns, and steel supports, offering superior load-bearing capacity compared to the thin-walled version.

5. Connection methods: flange connection, welding, groove clamp connection; suitable for large-scale pipelines.
