Flexible Rubber Joint Buried Protective Device

The flexible rubber joint buried protective device developed by our company is designed with enough space around and has no influence on rubber joints displacement performance and can separate rubber joint from exterior earth layers and keep pipes freely moving at device ends without resistance. After installing pipes lines, the backfilled ground will be leveled off as usual, on which, vehicles can run well, heavy materials are placed or equipment be installed.

   The device is the only invention in the country, and it was ever well used in Guangdong Dongguan 4th Water Supply Plant, Qinghai Salt Lake Project and Shanghai Changqiao Water Supply Plant in 2000, 2001 and 2002. 

  Special attention: please provide buried depth in order so that we can design reasonable protective device for you. Generally the device can be used for over 30 years if anti-erosion on the device surface is well done.   

we product have been use in many named factories and this one is Gangan power plant.
