Guyang-Baiyin Obo Gas Pipeline Project Guyang First Station and Valve Chamber Passed Acceptance, Hydrogen-Blended Transmission Project Moving Toward Commissioning

Recently, the Guyang-Baiyin'ebo Gas Transmission Pipeline Project's Guyang First Station and valve chamber, constructed by Shaanxi Construction & Installation Group, successfully passed the completion acceptance inspection. This key period marks a solid step toward official commissioning for this innovative infrastructure project equipped with a 20% hydrogen-blending transmission capability.

It is reported that the Guyang-Baiyin'ebo Gas Transmission Pipeline Project is a key construction project under the "County-to-County Connection in Western Inner Mongolia" initiative of the Inner Mongolia Autonomous Region's 14th Five-Year Oil and Gas Development Plan. The pipeline stretches 125 km in total, starting from the Guyang First Station and running northward through Guyang County and Darhan Muminggan Joint Banner in Baotou City and the Baiyin'ebo Mining District, with its terminus at the Barun Industrial Park. As a distinctive project equipped with a 20% hydrogen-blending transmission capability, its completion and commissioning will drive the formation of a new interconnected ring-network gas supply pattern in the central and western regions of the Inner Mongolia Autonomous Region, further enhancing energy supply security.

This project is of great significance to the development of Baotou City. It will help this "World Capital of Rare Earth and Grassland Steel City" optimize its energy structure, improve production efficiency, and reduce energy costs, while providing energy support for technological innovation and industrial upgrading in the rare earth industry, building a stable energy supply chain, and strengthening the overall economic strength of the region.

During the construction period, the Shaanxi Construction & Installation Group project team, upholding the enterprise philosophy of "Building for Good," successfully overcame challenges such as a short effective construction window and complex construction conditions. At the Kundulun River crossing section, the team employed large-scale horizontal directional drilling technology with round-the-clock operations, achieving a successful single-pass crossing with a 100% pass rate in conductivity testing. In addition, the project was the first in China to implement the new standard "Steel Pipes for Pipeline Transportation Systems in the Petroleum and Natural Gas Industry," verifying the feasibility of large-scale, long-distance hydrogen transportation using spiral submerged arc welded pipes and contributing to the realization of the nation's "dual carbon" goals.
