Industrial Expansion Joints, Seals & Special Valves
Industrial ducting and piping systems in steel mills, power plants, and chemical units are subjected to extreme thermal expansion, mechanical vibrations, and pressure spikes. To compensate for these stresses and maintain process integrity, Excellors manufactures a comprehensive range of premium expansion joints and custom sealing solutions.
Our rounded metallic expansion joints range from DN 50 to DN 8000 mm, absorbing high thermal displacement under severe pressures. For ducting systems carrying hot air or dust-laden flue gas, our fabric expansion joints offer unmatched flexibility. We also supply custom rubber expansion joints and heavy-duty rubber or metallic seals for all types of industrial valves, including specialized sealing kits for Flap Gates.
In addition, we design and manufacture specialized swing-type equalizing and relief valves. Mounted vertically in the gas duct, these valves open against gas flow using a robust hydraulic lever mechanism, providing reliable and rapid pressure relief for material hoppers in abrasive, dust-laden environments.
