Compared with the single ball rubber joints,double ball rubber joint is not just more than a rubber ball,and also in the center of the part,there is a very small strengthening.
The reason why we have to increase a double ring,is based on lots of customers'response to increase the special design,and when we added the strengthen ring the pressure is very good, and also very good to ensure the safety of the most vulnerable part of the double ball rubber joints.
We produce the double ball rubber joints are widely used in pipeline compensation,powerplant pipeline medium.The double ball rubber joints we produce,in the middle layer used is high-quality nylon cord fabric and hard wire welding and the composition of the skeleton layer. It has very good strength,and ensure that the double ball rubber joints does not easily tear occurred,after compression deformation can also be good for restitution.We produce double ball rubber joints of nylon cord fabric of high toughness is guarantee of its toughness,and bead reinforcing layer is assurance of its strength.
