Buried Expansion Joints

Performance: Buried expansion joints is mainly used to absorb the axial movement along the axes of buried pipeline that caused by the thermal expansion or compression. It has characteristic that resistance to compression of soil, self-guided, the same life with the buried pipeline, do not need servicing and change. It design as compensation limit structure., and endure thrust. If the pipeline or the condition with corrosion medium, it can spray painting with corrosion proofing layer.
