Introduction: 1. Rubber Expansion Joints can greatly reduce pipeline system shock and noise. And can fundamentally resolve pipe joints displacement, axial stretch and nonconcentricity. 2. By using different materials, it can be made many kinds to cater for different medium and environment. Such as acid resistance, alkali resistance, corrosion resistance, oil resistance and heat resistance etc.
3. The material is pure rubber, sealing is very good. It is in light weight, very easy for installation . This product has long life performance, but must be not contact with sharp metal instruments to avoid piercing the sphere.
4. Rubber Expansion Joints aborber can be used for lift and transportation of raw water and sewage, transportation of water supply cooling cycle water thermal power ,condensate water of metallurgy industry and chemical industry,

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.
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.
