Is GUARDIANÂ® ELECTRO anti-static shielding hose safe for continuous use at +110Â°C or only for short-term exposure?

GUARDIANÂ® ELECTRO anti-static shielding hose is designed for continuous operation in the range â40Â°C to +90Â°C. The specification notes a temporary (short-term) capability up to +110Â°C, which means exposure at +110Â°C is allowed only for short durations and not for continuous service. Continuous use at +110Â°C would exceed the hoseâs rated operating temperature and could degrade materials (EPDM inner, CR outer, textile reinforcement), reduce service life, and compromise safety and performance. For applications requiring sustained operation at +110Â°C, consult the manufacturer for a hose rated for continuous use at that temperature or verify permitted duty cycles and thermal limits with technical support.

Can GUARDIANÂ® ELECTRO anti-static shielding hose be used continuously at 10 bar working pressure across the full -40Â°C to +90Â°C range?

No. GUARDIANÂ® ELECTRO anti-static shielding hose has a rated working pressure of 10 bar and an operating temperature range of â40Â°C to +90Â°C (temporary up to +110Â°C), but continuous use at the maximum working pressure across the full â40Â°C to +90Â°C range is not advised without manufacturer confirmation. The specification gives burst pressure (30 bar) and a working pressure (10 bar) but does not guarantee continuous 10 bar performance at all temperatures; low temperatures can affect flexibility and material properties, and the bend radius is specified only at 1 bar. For safe continuous operation at 10 bar across the full temperature range, consult the manufacturer for temperature-pressure derating and installation guidelines.

Can GUARDIANÂ® ELECTRO anti-static shielding hose resist ozone and radiant heat from arc furnaces without degradation?

Yes. GUARDIANÂ® ELECTRO anti-static shielding hose is designed for metallurgical environments and its outer CR rubber layer is specifically resistant to ozone and radiant heat from electric arc furnaces. The hose features very high electrical insulation (R > 10^10 Î©/m) and breakdown resistance > 6 kV/mm, is selfâextinguishing (meets ASTM Câ542), and its materials and construction (EPDM inner layer, textile braid reinforcement, CR outer layer) suit cooling and protective duties. Operational temperature range (â40Â°C to +90Â°C, temporarily up to +110Â°C), working pressure 10 bar and burst 30 bar further support its use without degradation under the described furnace conditions.
