| Mn | 0.27 – 0.63 |
| P | ≤ 0.035 |
| S | ≤ 0.035 |
| Fe | Balance |
| Property | Value |
|---|---|
| Tensile Strength | ≥ 325 MPa |
| Yield Strength | ≥ 180 MPa |
| Elongation | ≥ 35% |
| Hardness | ≤ 72 HRB |
| Max Operating Temp | Up to 400°C |
Compact Design
U-bending allows longer tube lengths to fit within limited spaces, reducing required shell diameter.
Fewer Welding Points
The continuous U-shape reduces the number of weld joints, lowering failure risks and improving system integrity.
Improved Thermal Efficiency
Seamless structure and uniform wall thickness ensure efficient heat transfer and fluid flow.
NDT Tested
Tubes are hydrotested and can undergo eddy current or ultrasonic testing to ensure reliability in pressure environments.
Commonly used in:
Heat Exchangers
Steam Condensers
Boiler Superheaters
Air Coolers
Oil and Gas Refineries
Power Plants (HRSG Units)
