Can E-BR flange rubber expansion joint be used with oil, fat or petroleum-based media?

No . the E-BR flange rubber expansion joint must not be used with oils, fats or petroleum-based media. The product description explicitly states these compensators are intended for abrasive media like suspensions, sediments, emulsions and water with solid additives, and are not intended for media containing oils, fats or petroleum products. The bellows are marked with a single blue dot; inner and outer layers are BR/NR rubber, reinforcement is polyester braid, flanges are galvanized carbon steel, and operating temperature range is -50Â°C to +70Â°C (temporarily +90Â°C depending on the medium).

Can E-BR flange rubber expansion joint handle abrasive slurries with suspended solids at temperatures up to +90Â°C?

Yes - the E-BR flange rubber expansion joint is designed for abrasive slurries with suspended solids. Its inner and outer BR/NR rubber layers and polyester braid reinforcement provide exceptional abrasion resistance, suitable for suspensions, sediments and emulsions containing solid, abrasive elements. Operating temperature range is -50Â°C to +70Â°C, with temporary use up to +90Â°C depending on the medium; verify that your specific slurry allows the temporary +90Â°C exposure. Not suitable for oils, fats or petroleum products.

Is E-BR flange rubber expansion joint suitable for use with highly alkaline or acidic corrosive fluids?

E-BR flange rubber expansion joint is not suitable for use with highly alkaline or highly acidic corrosive fluids. Its construction (inner and outer layers of BR/NR. butadiene rubber/natural rubber. and polyester reinforcement) and intended applications indicate resistance primarily to abrasive, particulate-laden media (suspensions, sediments, emulsions, water with additives containing solids). The product is explicitly not intended for media containing oils, fats, or petroleum products, and there is no specification of chemical resistance to strong acids or alkalis. Additionally, the flanges are galvanized carbon steel, which can corrode under aggressive acidic or alkaline conditions. Operating temperature range (-50Â°C to +70Â°C, temporarily +90Â°C) does not imply chemical compatibility. For highly corrosive acidic or alkaline fluids, select a compensator made of chemically resistant elastomers (e.g., EPDM, FKM, PTFE-lined designs) and corrosion-resistant flanges (stainless steel, Hastelloy, or appropriate coatings), and verify compatibility with the fluid and concentration before use.
