Is the E-RP flange rubber expansion joint suitable for drinking water and seawater but not for oil-laden systems or pressures above 10 bar?

Yes. The E-RP flange rubber expansion joint is suitable for drinking water and seawater . itâs explicitly designed for sanitary installations, cold and hot water, pool water, seawater and drinking water. It is not suitable for mineral oils, cooling water with oil-containing corrosion inhibitors, oil-laden air, nor for systems where the constant working pressure exceeds 10 bar. Marking: single red dot on the sleeve. Materials: inner layer butyl (IIR)/EPDM, reinforcement nylon cord, outer EPDM, flanges galvanized carbon steel. Operating temperature range â40Â°C to +90Â°C (temporary up to +120Â°C depending on medium).

Can the E-RP flange rubber expansion joint handle temperatures up to +120Â°C temporarily depending on the medium?

Yes. The E-RP flange rubber expansion joint is rated for an operating temperature range of -40Â°C to +90Â°C, and it can withstand temporary peaks up to +120Â°C depending on the medium. Ensure the medium is compatible (suitable for sanitary installations, cold/hot water, pool water, seawater, drinking water) and avoid use with mineral oils, oil-containing corrosion inhibitors, oil-laden air, or where constant working pressure exceeds 10 bar.

Does the E-RP flange rubber expansion joint use EPDM outer layer and butyl inner layer for corrosion resistance?

Yes. The E-RP flange rubber expansion joint uses an EPDM outer layer and a butyl (IIR) inner layer, as stated: Inner layer: butyl rubber (IIR) / EPDM and Outer layer: EPDM rubber. This construction provides corrosion resistance suitable for sanitary installations, cold/hot water, pool and seawater, and drinking water, but it is not suitable for mineral oils, oil-laden systems, or applications above 10 bar.
