VI. Selection and Installation Notes

1. Key Selection Points:
   • Medium properties: NBR for oils, EPDM for acids/alkalis, silicone for high-temperature steam;
   • Pressure fluctuations: Choose 1.6MPa high-pressure type with limit devices for frequently starting/stopping pumps.
2. Installation Requirements:
   • Tighten bolts symmetrically with torque controlled at 30~40N·m (for M16 bolts);
   • Avoid direct sunlight or sharp objects; add sun-protective coating (e.g., neoprene) for outdoor use;
   • Install metal flexible joints on the pump side to buffer high-frequency vibrations.

VII. Typical Application Scenarios

• Industrial: DN100 hydraulic oil pipes (NBR, 1.6MPa) compensating pump vibration;
• Building: DN100 firewater pipes in high-rises (EPDM, 1.0MPa) absorbing pump start-up thrust;
• Food: Beverage production lines (silicone + 304 flanges, FDA-certified), resistant to 80℃ and non-toxic.
