The 2026 China-Europe Pipeline Engineering and Trenchless Rehabilitation Technology Academic Conference grandly opened in Shenyang. As a technical pioneer in the trenchless rehabilitation field, Dongguan Ergu Optoelectronics Technology Co., Ltd. (hereinafter referred to as "Ergu Optoelectronics") was invited to attend. The company showcased its two core products—the UV Curing System and the Thermal Curing Air Pressure Inversion Drum—gaining significant industry attention.

Dual-Curing Solutions Covering Diverse CIPP Rehabilitation Needs

The UV Curing System and Thermal Curing Air Pressure Inversion Drum exhibited by Ergu Optoelectronics correspond to the two mainstream processes in CIPP rehabilitation—UV curing and thermal curing—providing flexible and efficient technical options for urban underground pipeline rehabilitation.

UV Curing System: Rapid Curing, Precision, and High Efficiency

This system adopts advanced light source control technology, using specific wavelengths of ultraviolet light to activate photosensitive resin, achieving fast and uniform curing of the liner pipe. Its intelligent control system can monitor the curing process in real time, ensuring the formation of a high-strength, corrosion-resistant "pipe-within-a-pipe." The cured liner pipe can have a service life of up to 50 years, significantly shortening the construction period. It is suitable for municipal pipeline rehabilitation projects with stringent timeline requirements.

Thermal Curing Air Pressure Inversion Drum: Stable Conformity, Adaptable to Complex Scenarios

As a core equipment for the thermal curing CIPP process, this Air Pressure Inversion Drum ensures smooth inversion and conformity of the liner tube impregnated with thermosetting resin through precise air pressure control. Its optimized structural design is adaptable to various pipe diameters from DN60 to DN500mm. Combined with the subsequent thermal curing process, it can effectively handle complex conditions such as pipe deformation and joint leakage, ensuring the liner pipe fits tightly against the inner wall of the original pipe, forming a corrosion-resistant, high-strength rehabilitation liner.

Dual-Track Approach, Adapting to Diverse Industry Rehabilitation Scenarios

Ergu Optoelectronics' UV Curing System and Thermal Curing Air Pressure Inversion Drum address the core requirements of the UV curing and thermal curing CIPP processes respectively, establishing a rehabilitation equipment system covering diverse scenarios. The UV Curing System, with its advantages of rapid curing and low environmental impact, is suitable for scenarios demanding high construction efficiency, such as urban main roads and commercial districts. The Thermal Curing Air Pressure Inversion Drum demonstrates excellent performance in scenarios like aging pipeline networks and complex terrains, thanks to its stable air pressure control and wide pipe diameter adaptability.

During the exhibition, Ergu Optoelectronics' technical team engaged in in-depth exchanges with participating experts and industry representatives on topics such as the selection between UV curing and thermal curing processes in CIPP rehabilitation and equipment adaptation in complex scenarios. The company stated that it will continue to focus on the diverse needs of trenchless rehabilitation technology, aiming to contribute to enhancing the safety, resilience, and green, low-carbon transformation of urban underground pipeline networks with a more comprehensive equipment system.

By presenting the dual-curing solutions at this conference, Ergu Optoelectronics demonstrated its technical expertise in the trenchless rehabilitation field, contributing corporate strength to promoting the diversified application of industry technology and the integration of industry, academia, and research.
