HRSG boiler casing, bypass and main chimneys supply

The peculiarity of this project have to be found in the By-Pass chimney manufacturing low alloyed material ASTM SA-387 Gr.11 Cl.2.
The high temperatures of gas turbine exhaust (> 600 ° C) highly stressed this item by a thermal point of view. The construction in low alloy material, has requested the execution of specific procedures and processes of welding and heat treatment PWHT. Due to the size of this item, we performed the local PWHT inside to Scandiuzzi workshop.
