Is the Sapphire screw-in nozzle, type 965 compatible with fluids used at pressures up to 3000 bar and temperatures up to +150Â°C?

Yes. The Sapphire screw-in nozzle, type 965 is specified for a maximum working pressure of 3000 bar and an operating temperature up to +150Â°C, so it is designed to be compatible with fluids used under those pressure and temperature conditions. Ensure assembly respects the maximum tightening torque (max. 25 Nm) and verify fluid chemical compatibility with sapphire and any sealing materials used.

Can the Sapphire screw-in nozzle, type 965 withstand repeated tightening cycles up to the max torque of 25 Nm without performance loss?

Based on the provided specifications, the Sapphire screw-in nozzle, type 965 is rated for a maximum tightening torque of 25 Nm and for use at pressures up to 3000 bar and temperatures up to +150Â°C. The specification of a maximum torque implies the design and materials (including the sapphire or its mounting) are intended to tolerate tightening up to 25 Nm. However, the information does not explicitly state durability under repeated tightening cycles. Therefore, while a single correct torque application (â¤25 Nm) is within the nozzleâs rated limits, there is no explicit guarantee in the given description that repeated tightening to the maximum 25 Nm will not cause cumulative wear or eventual performance loss. For assurance on cycle life, fatigue or repeated-use testing data from the manufacturer should be requested.

Does the Sapphire screw-in nozzle, type 965 require special maintenance after exposure to 3000 bar and +150Â°C?

No. The Sapphire screw-in nozzle, type 965 does not require special maintenance solely because it has been exposed to its rated limits (3000 bar and +150Â°C), provided it has been used within the specified operating conditions and tightening torque (max. 25 Nm). Standard inspection and maintenance best practices are recommended: - Visually inspect the nozzle and seating area for signs of wear, cracks, chipping or thermal damage. - Check sealing surfaces and threads for deformation or contamination; clean gently with appropriate solvents and soft, non-abrasive tools. - Verify threads and mating parts are undamaged before reinstallation; replace the nozzle if any damage is found. - Ensure reinstallation torque does not exceed 25 Nm to avoid overstressing the assembly. - If the nozzle was exposed to contaminants or corrosive media, perform additional cleaning and, if needed, replace rather than reuse. - For critical or safety-related systems, consider periodic functional testing or replacement intervals per your operating procedures. If any abnormalities (leaks, performance loss, visible damage) appear after exposure, replace the nozzle rather than attempt repairs.
