FAQ: Can Electromagnetic Flow Meters Handle High-Pressure Water Injection up to 42MPa?
Q: What are the pressure and temperature limits for RBHEF Magmeters in water injection service?
A: Our RBHEF Series is specifically engineered for critical oilfield services. It supports temperatures up to 180°C and pressures reaching 42MPa.
Important Technical Note on Pressure: The maximum pressure rating is dependent on the nominal diameter (DN):
• High-Pressure Customization: For DN15–DN100, we provide specialized high-pressure flanges and reinforced sensor bodies to reach 16MPa, 25MPa, or 42MPa.
• Standard Sizes: For larger diameters, the pressure rating follows international flange standards (ANSI/DIN).
Q: Which materials are recommended for low-sediment oil well injection?
For standard water injection with minimal sand content, we recommend:
• Electrodes: SS316L (Excellent cost-performance for clean/low-sediment water).
• Lining: FEP (Superior 180°C heat resistance and chemical stability).
• Excitation: Multi-frequency technology to ensure zero-point stability under high-pressure pulses.
