The 180 Deg. Short Radius U Bend Return in ASME SA234 WPB is specifically designed for fired heater convection sections. These U bend returns are widely used in power plants, petrochemical facilities, and oil refineries where space constraints often require short radius (SR) configurations.
Manufactured through hot forming or cold hydro forming processes, these returns are essential for connecting pipes/tubes in high-temperature environments. For furnace applications, cast types are typically specified.
Yuhong Group implements rigorous quality control measures including 100% PT/UT/MT testing prior to shipment to ensure compliance with industry standards.
