Description

EN 10216-2 P265GH Carbon Steel Boiler Tube Seamless Steel U Bend Tube Square Bending

The Only Real “U‑bend” Application in a Water Wall – Roof or Floor

In a few boiler types, a 180° return bend is used, but the tube is horizontal, not vertical:

  • Water‑cooled floor (fluidised bed): Tubes run horizontally, make a 180° U‑turn at the side wall, and return. These are genuine U‑bends.

  • Water‑cooled roof (top of furnace): Similar horizontal serpentine with U‑bends at the roof edge.

In these cases, the tube is still called a water wall tube (because it forms part of the furnace enclosure), and EN 10216‑2 P265GH is acceptable for pressures up to ~160 bar and temperatures up to 400°C.

Key difference: These U‑bends are cold‑bent with a mandrel, stress‑relieved, and have a large centre‑line radius (≥ 2.5× OD) to avoid thinning and ovality.

If you are procuring seamless P265GH U-bends (e.g., for an economizer in a waste heat boiler):

  • Hot Bending: Normalized after bending (re-qualifies to P265GH).

  • Cold Bending: Must be stress relieved at 580–620°C if outer fiber strain > 15% (per EN 12952).

  • Thinning: Outer wall thinning cannot exceed 12–15% of nominal thickness.

  • Ovality: Max 10% for pressure parts (tighter for membrane welding).

  • NDT: 100% liquid penetrant (PT) on the bend extrados (outer curve).

Applications

  • Superheater

  • Economizer, industrial boilers

  • Power plant steam lines (subcritical)

  • Heat exchangers in refineries and chemical plants

  • Pressure vessels for elevated temperature service
