Description
ASME SA179 Carbon Steel U Bend Boiler Tube 25.4mm OD 2.77mm WT Custom Radius Shell Tube Heat Exchanger Application
ASME SA179 Carbon Steel U Bend Seamless Boiler Tube

ASME SA179 U Bend Tubes are manufactured from cold-drawn seamless carbon steel tubes, precision bent to exact customer specifications for shell and tube heat exchangers. These U-bend tubes eliminate the need for return headers, reducing potential leak points and improving heat exchanger reliability in refinery, petrochemical, and power plant applications.

Custom Bending Capability
  • Wide Bend Radius Range: Standard bend radii from 1.5D to 3D, custom radii available per customer drawings
  • Precision Bending: CNC-controlled cold bending ensures consistent wall thickness at the extrados and intrados
  • Post-Bend Heat Treatment: Stress relief annealing available for tight radius bends to restore material properties
  • Multi-Bend Capability: Single and double U-bend configurations available
  • Full NDT on Bend Area: Dye penetrant inspection on bend extrados and intrados to verify bend integrity
Material Specifications
