2026 China-Europe International Conference on Pipelines and Trenchless Technology was grandly opened in Shenyang. As a technological pioneer in the field of trenchless rehabilitation, Ergu Optoelectronics Technology Co., Limited(hereinafter referred to as "Ergu Optoelectronics") was invited to attend and presented two core products: the UV light curing system and the thermal curing pneumatic reversing drum, which won high attention in the industry.
Dual-curing solutions cover multiple needs of CIPP rehabilitation
The UV light curing system and the thermal curing pneumatic reversing drum exhibited by Ergu Optoelectronics this time respectively correspond to the two mainstream technologies of light curing and thermal curing in CIPP pipeline rehabilitation, providing flexible and efficient technical options for the rehabilitation of urban underground pipelines.
UV curing system: Rapid forming, precise and efficient
This system employs advanced light source control technology. It activates the photosensitive resin with specific wavelength UV rays, enabling the inner liner of pipeline to be cured quickly and uniformly. The intelligent control system can monitor the curing process in real time, ensuring the formation of a high-strength and corrosion-resistant "pipe in pipe" structure. The cured inner liner pipe can last for 50 years, significantly shortening the construction period and is suitable for municipal pipeline repair projects with strict time requirements.
Thermal curing pneumatic reversing drum: Stable adhesion, suitable for complex scenarios
As the core equipment of the thermal curing CIPP process, this pneumatic reversing drum precisely controls the air pressure to achieve the smooth flipping and bonding of the inner liner hose immersed with thermosetting resin. The optimized structural design can be adapted to various pipe diameters ranging from DN60 to DN500mm. Combined with the subsequent thermal curing process, it can effectively satisfy complex situations such as pipe deformation and interface leakage, ensuring a tight fit between the inner liner pipe and the inner wall of the original pipe, forming a corrosion-resistant and high-strength repair of inner liner layer. The dual-track design is compatible with diverse repair scenarios in the industry.
The UV light curing system and thermal curing pneumatic reversing drum of Ergu Optoelectronics respectively address the core requirements of the two CIPP processes, forming a rehabilitation equipment system that covers various scenarios. The UV light curing system is characterized with its advantages of rapid forming and low environmental impact, which is suitable for scenarios such as urban main roads and commercial areas where high construction efficiency is required. The thermal curing pneumatic reversing drum with stable air pressure control and wide pipe diameter adaptability demonstrates outstanding performance in scenarios such as old pipelines and complex terrain.
During the exhibition, the technology team of Ergu Optoelectronics had in-depth discussions with the participating experts and enterprise representatives on topics such as the selection of light curing and heat curing processes in CIPP rehabilitation, and the equipment adaptation in complex scenarios. The company stated that he will continue to focus on the diversified needs of trenchless rehabilitation technology, he will help enhance the safety resilience and green and low-carbon transformation of urban underground pipelines with his more complete equipment system.
At this conference, Ergu Optoelectronics demonstrated his technical expertise in the trenchless rehabilitation field through dual-curing solutions, contributing the enterprise strength to promoting the diversified application of industry technology and the integration of industry-academia-research.
