Advantages of double ball rubber joints   

      1. Compensate for displacement: Double ball rubber joints can compensate for a certain displacement in the pipeline system to avoid pipeline rupture caused by temperature changes, earthquakes and other reasons, so as to protect the stable operation of the pipeline system.

      2. Corrosion resistance: The rubber material has good corrosion resistance, which can adapt to the transportation of various media and ensure the stable operation of the pipeline system.

      3. Easy installation: The installation of the double ball rubber joint is simple and convenient, only need to connect the flange with the pipe, no need to use welding or bolt fastening, saving installation time and cost.

      4. Economical: The price of double ball rubber joint is relatively low, the service life is long, the maintenance cost is low, and it is an economical and practical pipe connector.

How to install a double ball rubber joint

      1. It is strictly forbidden to over-displacement installation: When installing double ball rubber joints, the specified displacement limit must be observed, and the maximum displacement range allowed by the design must be avoided to ensure the normal function and safety of the joint.

      2. Symmetrical installation bolts: When installing bolts, you should ensure the alignment of the bolts and flange holes, and then gradually pressurize and tighten the bolts to prevent local leakage. Symmetrical mounting bolts ensure uniform stress on the joint and avoid local pressure concentrations.

      3. Use elastic pressure pads: For applications with working pressure of more than 1.6MPa, elastic pressure pads should be used on the bolts to prevent the bolts from loosening during work. Elastomeric pressure pads provide additional tightening force to ensure the sealing performance of the joint.
