High pressure heat exchanger tubes are critical in demanding thermal and pressure environments:
| Industry | Typical Uses | Why High Pressure Grade? |
|---|---|---|
| Oil & Gas | Feedwater heaters, high-pressure condensers, gas coolers | Extreme pressure and temperature cycling |
| Power Generation | Superheaters, reheaters, nuclear steam generators | High-temperature steam at elevated pressure |
| Chemical Processing | High-pressure reactors, synthesis gas coolers | Corrosive media under high pressure |
| Hydrogen Industry | Hydrogen coolers, heat exchangers | Hydrogen embrittlement resistance (Duplex) |
| Hydraulic Systems | Oil coolers for high-pressure hydraulics | Pressure spikes and fatigue resistance |
| Aerospace | Heat exchangers for engine and hydraulic systems | Extreme reliability requirements |
| Subsea | Subsea coolers, umbilical heat exchangers | External hydrostatic pressure resistance |
| Advantage | Benefit |
|---|---|
| Seamless construction | No weld line weakness – maximum burst strength |
| Thick wall capability | Withstands extreme internal pressures |
| High strength alloys | Duplex and super duplex for pressure + corrosion |
| Thermal fatigue resistance | Withstands rapid temperature changes |
| NACE MR0175 compliance | Suitable for sour service (H₂S environment) |
| Hydrostatic tested | 100% verified for leak-free performance |
| Traceability | Full material traceability from melt to final tube |
| Factor | Consideration |
|---|---|
| Wall thickness | Must be calculated based on internal pressure (Barlow's formula) |
| Material selection | Higher strength alloys allow thinner walls at same pressure |
| Bend radius | U-bends require larger radii to avoid wall thinning |
| Thermal expansion | Must be accommodated – U-tube design recommended |
| Testing | Hydrostatic or pneumatic testing required after fabrication |
