Anti-Corrosion Coating

Our LSAW pipes are equipped with anti-corrosion coatings designed to withstand aggressive environments, including protection against H2S and CO2 corrosion. This enhances the durability and lifespan of the pipes, making them suitable for challenging conditions.

Production Efficiency

Our plant features a vertical structure characterized by strong systematic characteristics, resulting in a compact footprint. The production process, from raw material crushing to grinding and packing, is an independent system that boasts a passing ratio of 99%, surpassing typical milling plants. The main frame is driven by airtight gearing and pulleys, ensuring smooth and reliable operation.

The electric control system is centralized, allowing for high automation, reducing the need for personnel in the operating room, thereby enhancing efficiency and safety.

Conclusion

LSAW steel pipes offer exceptional performance for high-pressure and structural applications, adhering to stringent international standards. With a commitment to quality and production efficiency, our LSAW pipes are engineered to meet the needs of diverse industries, ensuring reliability and durability in demanding environments.
