ERV Yellowsteel DN25-600

The ERV Yellowsteel rubber expansion joint is used for flexible connections in high-pressure pipeline systems for petrochemical applications. It is

suitable for use with fuels, DIN fuels with up to 50% aromatics, oil-contaminated cooling water, lubricant, hydraulic oil, and saltwater. The flanges of the ERV Yellowsteel are rotatable and standard available in DIN PN10 and PN16. The operating temperature depends on the medium and ranges from -20 °C to +90 °C. The ERV Yellowsteel is flame-resistant for 30 minutes at 800 °C, allowing machine chamber applications without using the optional fire protection cover. The maximum working pressure is 16 bar, 10 bar for the largest diameters.
