- Improper installation: If the tightening sequence or force is uneven during the installation of the Rubber Expansion Joint flanges, it may lead to poor sealing and subsequent leakage.
- Damage to the sphere (body): If the surface of the Rubber Flexible Joint sphere has damage, such as punctures from sharp objects or cracks caused by aging, it may also result in leakage.
- Air pore leakage on the Flange surface: Due to production process limitations, air pores may exist on the flange surface, which can become leakage points during installation or use.
- Material not resistant to medium corrosion: If the material of the Rubber Soft Joint cannot resist the corrosion of the pipeline medium, long-term use will lead to a decline in material performance and eventually leakage.
- Unreasonable sealing structure design: Improper sealing structure design may cause unevenness or roughness on the sealing surface between the joint and the pipeline, with impurities and damage, affecting the sealing effect.
- Aging and wear from long-term use: During long-term use, Rubber Flexible Expansion Joint may lose elasticity, develop cracks or wear due to aging and hardening, leading to leakage.
- Vibration or displacement of the pipeline system: Vibration or displacement of the pipeline system may cause uneven stress on the flexible rubber expansion joint, resulting in leakage.
- Medium temperature and pressure exceeding the joint's tolerance range: If the temperature and pressure of the medium exceed the design limits of the Rubber Joint, it may cause damage to the joint and subsequent leakage.
- Improper maintenance: Lack of regular inspection and maintenance may lead to wear of the rubber joint, loosening of fasteners, or contamination of the sealing surface, all of which can cause leakage.
- External factors: External impacts or damage, as well as environmental factors (such as extreme temperatures, ultraviolet radiation, etc.), may also lead to a decline in the performance of Rubber Joints and trigger leakage.
To prevent leakage caused by these circumstances, it is important to ensure proper installation of rubber joints, select appropriate materials and structural designs, conduct regular inspections and maintenance, and pay attention to the impact of environmental factors on rubber joints.
