double sphere rubber flange expansion joint

 Single and double sphere rubber expansion joints ball similarities and differences: The same point is a single sphere rubber expansion joints and double sphere rubber expansion joints absorb vibration and noise are mainly pipelines. The difference is that the installation length, axial and radial displacement and angular deflection displacement different. double sphere rubber expansion joints products, long length, displacement than the single sphere rubber expansion joints are also great, but the point of view of stability, single sphere rubber expansion joints than double sphere rubber expansion joints large stability.


Rubber expansion joints full range of superior performance, these rubber expansion joints using a variety of curing system, superior overall performance. Using effective and efficient semi-curing system can be curved flexible rubber joints. Compared with the conventional curing system, this joint is almost no reversion phenomenon, curing uniformity, good heat resistance, low compression deformation.
