Recently, the first high-performance PVC-UH pipe of Donghong Shares successfully rolled off the line, and the trial machine of the extra-large caliber high-performance PVC pipe production line was successful, marking that Donghong PVC-UH pipe production line has the production capacity of dn2000mm, and the product structure has achieved a new breakthrough.

Through the efforts of R&D center, equipment department, PVC workshop and equipment manufacturers, Donghong has become the only manufacturer in the world with the production capacity of dn2000mm ultra-large caliber PVC pipe, filling the gap in the field of hydraulic and municipal water supply and drainage of ultra-large caliber PVC pipe. At the same time, the technology has reached the international leading level, leading the development of the industry, becoming the only and first in the industry.

It is reported that ductile iron, PCCP and other metal or cement concrete pipes due to corrosion damage caused by about 20 years of service life, can not meet the long-term use of the market application needs. Donghong large-diameter high-performance PVC pipe has the comprehensive advantages of long service life of 100 years, good connection sealing and no leakage, high construction efficiency and short cycle, good cost performance and low cost, which helps the company occupy the market quickly in the fields of water conservancy engineering, municipal water supply and drainage, rain and pollution diversion.
