Product Description

The 180 Degree Short Radius U Bend Return is designed for high-performance applications in fired heater radiant sections. Manufactured from ASME SA234 WP9 material, this 4" SCH40 B16.28 compliant component is essential for demanding industrial environments.

These U bend returns are widely used in power plants, petrochemical facilities, and oil refineries. The short radius design is particularly valuable where equipment space constraints exist. Our returns are manufactured using hot forming or cold hydro forming processes, with cast types available for high-temperature furnace applications.

Each unit undergoes rigorous quality control including 100% PT, UT, and MT testing prior to shipment to ensure compliance with all standard requirements. These precision-engineered components serve as critical connections between pipes, tubes, and fin tubes in industrial systems.
