    Basic Process for Large Elbows

    First, weld a multi-faceted ring shell with a polygonal cross-section or a multi-faceted fan-shaped shell closed at both ends. After filling the interior completely with a pressurized medium, apply internal pressure. Under this pressure, the polygonal cross-section gradually transforms into a circle, forming a circular ring shell.
