Galvanized Carbon Steel EPDM Connector 3'' DN80 Double Ball Bellows Flanged Rubber Expansion Joint
Double ball rubber joint (also known as double ball rubber soft joint, double ball rubber flexible joint) is a flexible connection device used in piping systems, mainly used to absorb vibration, reduce noise, compensate for displacement (axial, lateral, angular) and adapt to thermal expansion and contraction.
Structure and composition
Double sphere design: It consists of two spherical rubber parts and a connecting flange in the middle, which has greater displacement compensation ability and flexibility than a single sphere.
Material:
Inner layer: medium-resistant rubber (such as natural rubber, nitrile rubber, EPDM, etc., selected according to the medium).
Reinforcement layer: multi-layer polyester cord or steel wire skeleton to improve pressure bearing capacity.
Outer layer: weather-resistant and ozone-resistant synthetic rubber (such as chloroprene rubber).
Flange: usually carbon steel galvanized flange or stainless steel flange.

Features and Advantages
Multi-directional compensation: can absorb axial, lateral and angular displacements, reducing pipeline stress.
Shock absorption and noise reduction: the elasticity of rubber effectively isolates vibrations and reduces fluid impact noise.
High pressure and corrosion resistance: choose different rubber materials according to working conditions (such as oil resistance, acid resistance, high temperature resistance, etc.).
Flexible installation: suitable for complex pipeline layouts and compensate for installation errors.
Long life: high-quality rubber is resistant to aging and has good wear resistance.
Main application areas
Water supply and drainage system: municipal water supply, sewage treatment.
HVAC: circulating water pipeline, fan coil connection.
Industrial pipeline: medium transportation in chemical, electric power, papermaking and other industries.
Fire protection system: pump room pipeline shock absorption.
Ships and rail transportation: flexible pipeline connection.
