Does the Suction and pressure silicone hose with increased pressure resistance SILICONE STAR/HD require pressure derating above +100Â°C and by how much per Â°C?

Yes. Suction and pressure silicone hose with increased pressure resistance SILICONE STAR/HD requires pressure derating above +100Â°C. For each 1Â°C above +100Â°C, reduce the maximum working pressure from the tables by 1% (i.e., 1% per Â°C). The hoseâs safety factor is 4:1 and its operating temperature range is -60Â°C to +180Â°C.

Can Suction and pressure silicone hose with increased pressure resistance SILICONE STAR/HD be autoclaved repeatedly without performance loss?

Suction and pressure silicone hose with increased pressure resistance SILICONE STAR/HD can be autoclaved repeatedly without significant performance loss, with some important conditions. Why itâs suitable: - Materials and approvals: Made of platinum-cured (platinum-enhancing) silicone, compliant with Regulation 1935/2004/EC, FDA 21 CFR 177.2600, USP Class VI, European Pharmacopoeia 3.1.9 and BfR XV. these indicate medical/pharmaceutical compatibility and suitability for sterilization processes. - Temperature range: Rated for continuous operation from -60Â°C to +180Â°C, covering typical autoclave cycles (121â134Â°C). - Construction: Reinforced with four polyester braids and an AISI 316 steel spiral, providing mechanical integrity under pressure and thermal cycling. Safety factor 4:1 gives margin against burst when used within specified working pressures. Practical limits and recommendations: - Reduce allowable working pressure above +100Â°C: for each 1Â°C above 100Â°C, reduce the maximum working pressure by 1% (apply the table values accordingly). This is critical during autoclave exposure at 121â134Â°C. - Repeated autoclaving: Repeated sterilization at autoclave temperatures is feasible, but long-term effects depend on cycle frequency, sterilization temperature, and exposure to aggressive media. Polyester braids may experience some loss of mechanical properties over many high-temperature cycles; monitor for softening, delamination, or changes in flexibility. - Chemical compatibility: Ensure the media being conveyed and any cleaning agents are compatible with silicone and stainless steel 316. Aggressive chemicals combined with heat can accelerate aging. - Inspection and validation: For critical applications, validate number of cycles through in-house testing (burst/pressure tests after defined cycles) and implement periodic visual and pressure inspections. Conclusion: Suction and pressure silicone hose with increased pressure resistance SILICONE STAR/HD is suitable for repeated autoclaving at standard sterilization temperatures when used within the reduced working pressure limits above 100Â°C and when chemical compatibility and regular inspection/validation are observed.
