What is EN 10216-2 P265GH U-Bend Tube?
EN 10216-2: European standard for seamless carbon steel tubes for pressure applications with specified elevated temperature properties.
P265GH: Carbon steel grade with good weldability and suitable for high-temperature pressure applications (yield strength ≥ 265 MPa).
U-Bend Tube: A tube bent into a U shape, commonly used in compact heat exchanger and boiler designs to allow directional changes without welds.
Why Use U-Bend Tubes?
Compact design: Saves space by reversing flow direction within small areas.
No welded joints: Maintains structural integrity under pressure and thermal cycling.
Good thermal expansion accommodation: The bend helps absorb expansion and contraction during operation.
Cost-effective installation and maintenance in boiler and heat exchanger systems.
