Maintenance problems of single ball rubber joints
2 . Install reliable and precise: when the pipeline offset is higher than or equal to the large compensation of the joint, the total number of the joint should be upgraded to parallel surface offset, and it is prohibited to become the deviation of the adjustment pipeline, so that even the joint at the upper limit of the tensile strain offset and road conditions, more super degree (expansion type, offset, offset, etc.).
3 . Installation at high places is to pay attention to: high-rise residential heating pipeline or hanging in the air to drainage, pipeline should be fixed immobile in the bracket, fixed bracket or anchor frame, cut can not let the connection head to bear the net weight of the pipeline itself and axial force, or the connection head should be configured to prevent pull off equipment. When installing the single ball rubber joint, the bolts of the foot bolt should be extended to both sides of the joint head, and the foot bolt of each piece of flange connection should be constantly and evenly torqued according to the steps of top angle negative pressure to avoid pressure deviation.
4 . Operation and maintenance: After the first time to withstand the force of the single ball rubber joint or before starting again after a long-term stop, the foot bolt should be pressurized and torqued again before the funds are put into operation.
5 . Mid and late maintenance solution: Application or storage of rubber joints should be prevented from high temperature, ozone oil and strong acidic and alkaline natural environment. The pipeline used in the outdoor or sun and wind should be built shade frame, prohibit exposure to the sun, rain, wind turbidity. The connection head surface layer is prohibited to paint and coil insulation materials. Due to the brittle problem of rubber products, it should be immediately tested and dismantled and replaced.
