Key Features

1. Large diameter, thick-walled construction with high compressive strength, high rigidity, and resistance to impact, suitable for high-pressure fluids and heavy structures.

2. The hot-dip galvanized coating offers dual corrosion protection, allowing it to be used outdoors and underground for extended periods, with a lifespan of 15–30 years.

3. Can be welded, connected using flanges, or connected using grooves, with strong adaptability for installation.

4. The inner surface is smooth, resistant to corrosion and scaling, and offers minimal resistance to fluid flow.
