Can the E-YS flange rubber expansion joint handle petroleum products with up to 50% aromatic content and temperatures from -35Â°C to +100Â°C (temporarily +120Â°C)?

Yes. The E-YS flange rubber expansion joint is specifically designed for petroleum-derived products and fuels with aromatic content up to 50%, as well as for cooling water with oil-based anticorrosive agents, lubricating and hydraulic oils, and seawater. Construction details supporting this use: - Inner layer: HNBR (hydrogenated nitrile) rubber . good resistance to aromatic hydrocarbons and oils. - Reinforcement: steel cord . provides strength and pressure resistance. - Outer layer: CR (chloroprene) rubber . weather, ozone and oil-resistant protection. - Flanges: galvanized carbon steel. - Marking: yellow-blue-yellow stripe on the sleeve indicates suitability for petroleum products. Operating temperature range is â35Â°C to +100Â°C, with short-term (temporary) use up to +120Â°C depending on the medium. Based on the stated materials and temperature limits, the E-YS flange rubber expansion joint can handle petroleum products with up to 50% aromatic content within the specified temperature range.

Is the E-YS flange rubber expansion joint suitable for seawater and cooling water containing oil-based anti-corrosive agents?

Yes. The E-YS flange rubber expansion joint is suitable for seawater and cooling water containing oil-based anti-corrosive agents. It is specifically designed for media including petroleum-derived products and fuels (aromatic content up to 50%), cooling water with oil-based anti-corrosive agents, lubricating and hydraulic oils, and seawater. Construction details supporting this suitability: inner layer HNBR (nitrile) compatible with oils, reinforcement of steel cord, outer CR (chloroprene) for weather and ozone resistance, galvanized carbon steel flanges, and operating temperature range â35Â°C to +100Â°C (temporarily up to +120Â°C depending on medium).

Does the E-YS flange rubber expansion joint use HNBR inner and CR outer layers for oil and fuel resistance?

Yes. The E-YS flange rubber expansion joint uses an HNBR (nitrile) inner layer for oil and fuel resistance and a CR (chloroprene) outer layer, as specified. It is designed for petroleum-derived products and fuels (up to 50% aromatic compounds), lubricating and hydraulic oils, cooling water with oil-based inhibitors, and seawater. Operating temperature range: -35Â°C to +100Â°C (temporarily up to +120Â°C depending on the medium).
