Reduced Concentric Rubber Expansion Joint Compensator - DN32 to DN200 Sizes with 20-35mm Axial Displacement
Our rubber expansion joint series includes single sphere, double ball, concentric diameter, reducing, food grade, and threaded connection variants designed for industrial piping systems.
- Compact design with lightweight construction and excellent elasticity
- Easy installation and maintenance with minimal space requirements
- Accommodates transverse, axial, and angular displacements during installation
- Compensates for pipeline misalignment and non-parallel flanges
- Reduces transmission noise and provides superior vibration absorption
Available in various rubber compounds including acid-resistant, flameproof, oil-resistant, thermostatic, low-temperature resistant, and wear-resistant materials to suit diverse industrial environments and media requirements.
Widely used in chemical processing, construction, water supply and drainage systems, oil industry, light and heavy industrial applications, refrigeration stations, water heating systems, fire fighting systems, and electrical power systems.
