How to select the right flange for high-pressure applications?
1. Understand the Application Requirements
- Fluid type: Is it water, oil, gas, or a corrosive chemical?
- Operating temperature: What temperature needs to be achieved and maintained?
- Operating pressure: What is the system's pressure rating (e.g., PSI or bar)?
- Flow rate: How fast is the fluid moving past the heater?
2. Choose the Right Flange Size and Rating
- Incoloy / Inconel: High temperature and corrosion resistance
- Stainless Steel 316/321: Good for corrosive or high-pressure environments
- Titanium: For aggressive chemicals
4. Determine Watt Density
- Keep watt density (W/in² or W/cm²) appropriate for the fluid to avoid:
- Fluid degradation
- Overheating or burnout
- Carbonization or scaling
- Lower watt densities are generally better for high-pressure systems where fluids are dense or have poor heat transfer properties.
