Is the REALÂ® delivery hose for highly aggressive chemicals suitable for continuous use above 50Â°C and what conditions apply?

The REALÂ® delivery hose for highly aggressive chemicals can be used continuously above 50Â°C, but only under specific conditions and after confirmation. The hoseâs operating temperature range is -25Â°C to +100Â°C and its inner layer is FKM (FPM, Viton) which gives high chemical and temperature resistance. However, for continuous service above 50Â°C (and for assurance of chemical compatibility at elevated temperatures) you must contact Tubes International for confirmation of resistance and exact application conditions.

Can the REALÂ® delivery hose for highly aggressive chemicals handle aromatic-rich fuels and solvents at elevated temperatures?

Yes - the REALÂ® delivery hose for highly aggressive chemicals is specifically designed for petrochemical use, including fuels with high aromatic hydrocarbon content, hot oil and solvents. Its smooth FKM (FPM, Viton) inner layer provides high overall chemical resistance and allows use with many aggressive, aromatic-rich fuels and solvents, often at elevated temperatures. Rated operating range is -25Â°C to +100Â°C and working pressure 10 bar. For confirmation of chemical compatibility and conditions-especially for temperatures above 50Â°C-contact Tubes International.

What precautions are required when using the REALÂ® delivery hose for highly aggressive chemicals near its 100Â°C limit?

When using the REALÂ® delivery hose for highly aggressive chemicals near its +100Â°C limit, take the following precautions: - Consult Tubes International before useâespecially for temperatures above +50Â°Câto confirm chemical compatibility and safe application conditions. - Limit operating temperature: do not exceed +100Â°C; consider safety margin below this limit for continuous use of aggressive media. - Monitor working pressure: ensure system pressure does not exceed 10 bar, accounting for pressure increases at elevated temperatures. - Inspect for chemical attack and aging: regularly check inner FKM (FPM) lining and outer CR cover for signs of swelling, embrittlement, cracking, or softening. Replace hose at first signs of degradation. - Control exposure duration: minimize residence time of hot aggressive chemicals in the hose; avoid prolonged stagnation at high temperature. - Ensure proper installation: avoid tight bends, kinks or mechanical stress that can accelerate wear at high temperatures; secure hose to prevent movement. - Manage external environment: protect from additional heat sources and ozone/UV where possible despite CR outer cover resistance; provide insulation or shielding if needed. - Use appropriate fittings and clamps resistant to chemicals and temperature to prevent leak paths. - Implement leak detection and emergency procedures: monitor for leaks, and have containment and shutdown plans because hot aggressive fluids increase hazard severity. - Follow maintenance schedule: increase inspection frequency when operating above +50Â°C or with aggressive chemicals; document service life and replace proactively. Adhering to these measures and obtaining Tubes Internationalâs confirmation for specific media and temperatures will help ensure safe, reliable use near the hoseâs temperature limit.
