Is the T-NBR flange rubber expansion joint compatible with mineral oils, vegetable/animal fats, aerosol oils, and water with anti-corrosive additives at temperatures up to +80Â°C?

Yes. The T-NBR flange rubber expansion joint is designed for use with mineral oils, vegetable and animal fats, aerosol oils, and water with anti-corrosive additives, and its construction (inner NBR layer, nylon braid reinforcement, outer NBR layer, galvanized carbon steel flanges) supports operation up to +80Â°C (depending on the medium).

Can the T-NBR flange rubber expansion joint handle food-grade oils and fats without degrading at temperatures up to +80Â°C?

Yes. The T-NBR flange rubber expansion joint is formulated for systems carrying mineral oils, vegetable and animal fats and aerosol oils, with an NBR (nitrile) inner layer and outer layer and nylon reinforcement. NBR has good resistance to oils and fats, and the productâs specified operating temperature is up to +80Â°C (depending on the medium). For typical food-grade mineral and vegetable oils and animal fats at temperatures up to +80Â°C, the T-NBR flange rubber expansion joint can be used without rapid degradation. Confirm compatibility with specific food-grade formulations, additives, and any regulatory or hygienic requirements for direct food contact before final selection.

Does the T-NBR flange rubber expansion joint resist swelling or chemical attack from anti-corrosive additives?

The T-NBR flange rubber expansion joint offers good resistance to many common anti-corrosive additives used in water and oil systems, but its resistance is not absolute and depends on additive type and concentration. Key points: - Construction: inner layer NBR (nitrile rubber), nylon braid reinforcement, outer NBR, galvanized carbon steel flanges. - NBR compatibility: NBR is generally resistant to mineral oils, vegetable and animal fats and many oil-related additives, so typical anti-corrosive additives formulated for oil systems are usually acceptable. - Water with anti-corrosive substances: some aqueous anti-corrosive formulations (especially those containing aggressive solvents, high concentrations of amines, nitrites, chromates, strong alkalis or oxidizers) can cause swelling, softening or chemical attack on NBR. - Temperature: maximum operating temperature up to +80Â°C can accelerate chemical attack or swelling if the additive is aggressive or used at elevated concentration/temperature. Recommendation: - Confirm the exact chemical composition, concentration and operating temperature of the anti-corrosive additive with the supplier. If the additive is a mild corrosion inhibitor intended for aqueous or oil systems, T-NBR flange rubber expansion joint will likely perform well; if the additive contains aggressive solvents, strong alkalines, oxidizers or exotic chemistries, perform compatibility testing or consult the joint manufacturer for approval.
