Longtaidi, Beyond Manufacturing, Shaping the Future:
Cladded Fittings Empower the World’s First Net-Zero Emission Natural Gas Project

The ADNOC Offshore High-Sulfur Gas Development Project, as the world’s largest offshore natural gas project, it serves not only as the driving force behind the UAE’s goal of achieving self-sufficiency in natural gas, but also as the world first net-zero emission natural gas project, setting a global benchmark for green energy transformation.

In this epic endeavor, Longtaidi Pipe Technology proudly plays a critical role, supplying large-diameter, high-pressure, weld overlay cladded flanges. Due to their superior performance and technical advantages, these products have stood out in a highly competitive international supply chain, representing the excellence of Chinese intelligent manufacturing in this landmark project.

For key applications such as subsea pipelines, high-pressure risers, and sulfur treatment terminals, Longtaidi flanges, featuring weld overlay clad structures with nickel-based alloy layers, are engineered to meet extreme challenges. These flanges provide exceptional high-temperature, high-pressure, and high-sulfur corrosion resistance, as well as outstanding oxidation resistance. They significantly reduce maintenance costs while ensuring no leakage and no failure throughout the subsea pipeline system.

Longtaidi’s overlay-welded clad technology leverages advanced automated 3D printing welding processes to precisely control alloy layer thickness and uniformity, achieving an optimal balance between performance and cost. With its customized service model, Longtaidi delivers tailored, scenario-specific solutions for diverse applications including subsea pipelines and sulfur treatment systems.

From the Persian Gulf to the global stage, and from traditional oil & gas to the frontier of renewable energy, Longtaidi drives innovation to break through technical bottlenecks and proudly etches the name of Chinese high-end manufacturing on the map of global green energy.
