Jining Yanzhou Daan Airport Pipeline Network Project
It is the largest civil airport in Lunan area of Shandong Province, and the annual passenger throughput is planned to reach 2.6 million in 2025, and the cargo and mail throughput will reach 7,000 tons.
The project uses Donghong Pipe Industry's store threading pipe PVC-O dn110, 160, 200mm pipe. In the poor construction environment, geological conditions, such as staggered, the superiority of PVC-O sheath pipe can be fully realized. The pipe is formed into a laminated structure by molecular biaxial orientation, which gives the pipe excellent toughness and impact resistance. In the loading and unloading process can resist great external impact, life longer. PVC-O sheath pipe can greatly save raw material resources, reduce costs and improve the protection performance of electric power, communication system.
