Beijing, May 2025 – The World Gas Conference, held under the theme “Empowering a Sustainable Future,” brought together over 3,000 industry leaders from 70 countries and regions in Beijing. The event served as a pivotal platform for in-depth discussions on global energy transition, the future of natural gas, and pathways toward a sustainable energy landscape. As the world’s largest importer of natural gas and LNG, China’s experience and practical advancements in the energy sector drew significant international attention. Once again, “Made in China” impressed the global audience with its exceptional capabilities.

Among the standout participants was Donghong Pipe Industry Co., Ltd., which with 28 years of dedicated innovation and self-developed technology, has broken through international technical barriers. Starting from a single composite pipeline breakthrough, the company has developed a complete industrial chain that includes intelligent pipeline network systems—each achievement redefining what “Made in China” represents.

Since 2000, Donghong Pipe Industry Co., Ltd. has been introducing internationally advanced production equipment, including more than 20 German-origin PE production lines, to build high-standard workshops dedicated to manufacturing PE gas pipes. Every production line is equipped with state-of-the-art systems such as Italian centralized dehumidifying and drying feed systems, German gravimetric batch metering, and ultrasonic thickness measurement. The workshops are constructed in strict compliance with both the American Petroleum Institute (API) standards and domestic G5+ requirements.

In 2020, the company further upgraded its operations by introducing a fully computerized German centralized feeding system. This innovation eliminates human error in material mixing and usage, significantly enhancing product consistency and stability. All production processes are digitally monitored, ensuring full traceability and transparent management. With fully enclosed management of raw materials and precision proportioning, Donghong continues to elevate its automation level, guaranteeing superior product quality.

This rapid growth is attributed to both precise national policy support and the company’s enduring commitment to independent R&D. Embracing a culture of innovation characterized by “aiming high, pioneering boldly, collaborating intelligently, and working unitedly,” Donghong’s R&D team has achieved multiple technological breakthroughs in gas pipeline systems, providing a solid foundation for the enhancement of China’s gas pipeline network safety.

Product Highlights:

1. Polyethylene (PE) Gas Pipeline System

Donghong’s PE gas pipelines are produced and tested in strict accordance with national standards. The pipes are made from premium polyethylene resin supplied by internationally renowned chemical companies such as Borealis, SABIC, and TotalEnergies. Manufactured using German production technology and compliant with G5+ quality standards, the system offers lightweight properties, easy installation, leak-proof performance, and high resistance to corrosion, chemicals, organic solvents, and environmental stress cracking. It is widely applied in urban gas network construction.

2. 3PE Anti-Corrosion Gas Pipeline System
Donghong’s 3PE anti-corrosion pipeline system effectively prevents corrosion, greatly extending the service life and safety of pipelines. Designed for long-distance natural gas transmission and mainline projects, it reliably performs even in complex geological environments, ensuring secure energy transportation.

Project Case:

In the challenging Hetian Limin Gas Project, Donghong demonstrated formidable manufacturing and logistical capabilities, delivering 5,200 tons of pipelines over a transportation span of 4,300 km—all within 60 days, without compromising on quality. This project reflects the company’s unwavering dedication to craftsmanship and its commitment to maintaining the vitality of urban gas infrastructure. Upholding a market- and customer-centric philosophy, Donghong ensures every product meets the highest standards of excellence.

Moving forward, Donghong Pipe Industry Co., Ltd. will continue to deepen its expertise in gas transmission technology, delivering even higher-quality products that contribute to national energy infrastructure and safeguard the safety and well-being of communities.
