Product Introduction
Threaded rubber expansion joint is an important industrial connector, which is widely used in various industrial piping systems. It is mainly composed of an inner rubber layer, a reinforcing layer, an outer rubber layer and a joint body. When the piping system is subjected to external force or temperature changes, the rubber layer in the joint body will be elastically deformed, thereby absorbing and relieving the stress of the piping system. The reinforcement layer provides sufficient support to ensure that the joint does not crack or deform when subjected to pressure.
Features
1. Good elasticity and elastic performance: Rubber expansion joints can be freely expanded and contracted
within a certain range to adapt to various deformation needs of the
pipeline system.
2. Excellent corrosion resistance: The rubber material has good corrosion resistance, can adapt to
various media environments, and ensures the long-term stable
operation of the pipeline system.
3. Shock absorption and noise reduction effect: Rubber expansion joints can effectively absorb vibration and noise
in the pipeline system and improve the smooth operation of the
system.
4. Strong adaptability: Suitable for the connection of water supply and drainage, HVAC,
fire protection and other systems, especially in the need for shock
absorption and noise reduction, rubber joints are indispensable and
important components.

Product Applications
1. Building water supply and drainage system: In the water supply and drainage system of the building, the
rubber joint can effectively absorb and alleviate the displacement
or vibration of the pipeline due to thermal expansion and
contraction, foundation settlement and other reasons, maintain the
stability of the pipeline system, reduce the vibration and noise of
the pipeline, and provide a more comfortable use environment.
2. Industrial circulating water system: In the industrial circulating water system, the rubber joint
absorbs vibration and impact through its elastic structure,
protects the normal operation of pipelines and equipment, and
prolongs the service life. Its corrosion-resistant properties allow
it to perform well in circulating water containing chemicals,
avoiding equipment damage and leakage.
3. HVAC system: In the HVAC system, the rubber joint buffers the stress at the
pipe connection, protects the pipe interface from damage, and
reduces the noise generated by the operation of the equipment,
ensures the smooth operation of the system, and improves the
overall operation efficiency and user experience.
4. Water treatment and sewage treatment system: In the field of water treatment and sewage treatment, rubber
joints should cope with the erosion of various acid and alkaline
chemicals to ensure the long-term stable operation of pipelines. At
the same time, its chemical and ageing resistance makes it
excellent in these environments.
5. Petrochemical industry: In the petrochemical industry, rubber joints can cope with the
corrosive effects of high pressure, high temperature and chemical
media, absorb the shock and vibration in the pipeline system, and
ensure the stable operation of the pipeline system in complex
working environments.
