Reinforcement pipe

The reinforcement nozzle is manufactured as a single forged component, integrating the nozzle and a portion of the shell with the reinforcing section, and is subsequently welded to the shell and the nozzle. By concentrating the reinforcing metal in the region of maximum stress around the opening, this design most effectively reduces the stress concentration factor. A butt weld may be employed, with the weld and its heat-affected zone positioned away from the location of maximum stress, resulting in excellent fatigue resistance.

By concentrating the reinforcing material at the location of maximum opening‑induced stress, this approach most effectively reduces the stress concentration factor.
