Single ball rubber joint because of its own characteristics,prone to aging,or corrosion of the situation,our should regular inspection and replacement,Usually what problems always happen? Here they are:
1,single ball rubber joints cracking or crack
Some small crack may be not very obvious,our pipeline is exposure outside,with the time pass,will appear aging,there will be varying degrees of damage due to cracking,this situation can be timely replacement,we should try to avoid single ball rubber joints in the sun exposure,or is the wind and rain.
2,single sphere rubber joints by the bubble deformation
If there is a small part of the surface blisters or deformation, will not affect the performance,do not need to be replaced, only a regular inspection visits.If there is a big blister exists on the surface of the sphere,the deformation.If observed above the flange outer diameter of rubber cord fabric layer separation,rubber joints should be replaced as soon as possible.
3,single ball rubber joint model of the installation
Should check the installation is correct or not.Check over stretching,over compression, horizontal or angular misalignment.If the installation does not cause a single ball rubber joint is too large,should adjust the pipe to replace a rubber joint,in order to adapt to the existing installation. Finally, we should pay attention to the problem of leakage,if once found out leakage,we need to see whether the bolt is not tight,if the exclusion of this is likely to be a rubber joint ball damage or spherical design problems,should immediately replace the rubber joint. Ensure the normal operation of the pipeline.
