Donghong showcased its cutting-edge intelligent pipeline systems and smart water technologies at the 2025 Northeast (Shenyang) Water Expo, highlighting its leadership in digital water management and pipeline innovation.
At the event, the company presented advanced products such as intelligent pipeline terminals, trenchless rehabilitation solutions, and large-diameter composite pipes, demonstrating how digitalization and smart monitoring are transforming modern water infrastructure. Donghong aims to accelerate its strategic growth in Northeast China and contribute to building smarter, safer, and more sustainable water systems worldwide.

As a prominent participant in the World Gas Conference, Donghong Pipe Industry Co., Ltd. demonstrated its advanced gas pipeline systems—manufactured with German technology and strict international standards. With a strong track record in major projects such as the Hetian Limin Gas Initiative, the company ensures safe, reliable, and sustainable energy transmission infrastructure worldwide.

Donghong Co., Ltd. has launched mass production of its UV-resistant, black-inner-white-outer PE pipe, with initial sales success in Guinea, Africa. This product, achieved through a co-extrusion process, features a two-color structure: a white outer layer for reflective cooling and anti-aging properties, while a black inner layer ensures performance. This precisely matches the local high-temperature, high-UV environment, replacing the original steel-plastic composite solution, reducing costs and increasing efficiency. By strictly controlling raw materials and production processes, Donghong Co., Ltd. leverages technological innovation to build international market competitiveness and support its overseas strategy.
