Product Description:
The "flexible" characteristic of the single ball flexible rubber joint is its key function. In the pipeline system, there may be displacement, axial expansion or Angle change between pipes due to temperature changes, pipe settlement, equipment vibration and other reasons. Rubber joints take advantage of the elasticity of rubber materials and can flexibly adapt to these changes within a certain range.
For example, when the pipe is axially stretched, the rubber joint can extend accordingly, and when the pipe is axially compressed, it can shrink. For the lateral displacement and angular deflection of the pipeline, the rubber joint can also be compensated by its own elastic deformation, thereby effectively reducing the stress concentration of the pipeline system and protecting the pipeline and ancillary equipment from damage.
Features:
- It is mainly composed of an inner and outer rubber layer, a cord layer and a wire ring. The inner and outer rubber layer is the part that directly contacts the conveying medium and the external environment, and plays the role of sealing and protection. The rubber layer is generally made of high quality rubber, which has good corrosion resistance, aging resistance and sealing property, and can effectively prevent medium leakage.
- The cord layer is mainly used to enhance the strength and toughness of the rubber joint, so that it can withstand a certain pressure and tension. The choice of cord material and the number of layers will be determined according to the use of the rubber joint pressure and caliber size and other factors.
- The steel wire ring is arranged on the edge of the rubber joint, which plays a role of strengthening and shaping, and can prevent the excessive deformation of the rubber joint during pressure to ensure its stability and sealing.

Applications:
• Water supply and drainage engineering: widely used in urban water supply and drainage pipeline systems. Since urban underground pipelines may be displaced due to ground subsidence, earthquakes and other factors, the single ball flexible rubber joint can be well adapted to these changes to prevent pipeline breakage and water leakage. For example, in the connection of indoor water supply and drainage pipes in buildings, it can connect pipes of different materials, such as PVC pipes and cast iron pipes, while compensating for pipe installation errors and displacement caused by thermal expansion and contraction.
• Hvac system: Used in the chilled water, cooling water pipes and heating pipes of air conditioning. In the HVAC system, the pipe will expand significantly with the change of temperature. The rubber joint can absorb these expansion deformation, avoid the damage of the insulation layer or the pipeline itself due to excessive expansion, and ensure the normal operation of the system.
• Chemical industry: Pipeline system for conveying various chemical raw materials. Chemical pipelines usually transport corrosive liquids or gases, and the corrosion-resistant rubber layer of the single ball flexible rubber joint can effectively prevent the corrosion of the medium to the connection part of the pipeline. At the same time, it can adapt to the vibration and displacement of the chemical device during operation to ensure the safe and stable operation of the chemical pipeline.
