Single sphere rubber expansion joint is mainly used for reducing vibration, noise, good flexibility and easy to use.Single sphere rubber expansion join, also known as single ball rubber joint, rubber expansion joint, single ball connector , shock absorber, pipeline shock absorber, is a kind of pipeline joint with high elasticity, high air tightness, medium resistance and climate resistance.

Features: Absorb vibration, reduce noise, high pressure resistance, good elasticity, large displacement, balance pipe deviation, easy installation

Installation instructions

1 Single sphere rubber expansion joint shall not exceed the displacement limit during installation.

2 In the installation of bolts to be symmetrical, to gradually pressure and tighten, to prevent  partial  leakage.

3 When the single sphere connector is laid flat, suspended, and vertically installed, the actual working axial displacement pressure of the rubber joint should be less than the supporting force of the pipeline, otherwise the anti-lifting device should be installed to prevent the work from being pulled.

4 The installation location of single sphere rubber expansion joint should be kept away from the heat source and ozone area. It is strictly forbidden to irradiate with strong radiation, expose to the sun and use the medium that does not meet the requirements of this product.

5  When the flexible rubber joint is transported, loaded, unloaded or installed, it is strictly forbidden to sharpen the surface sealing surface.

6 When installing DN200mm or above, please use butterfly valve special flange or small diameter flange for mating flange, so as to avoid flange pull-out, misalignment, sealing surface fracturing and water leakage after installation.
