WPS with PWHT is enough, since your dished end is in single piece (no welds).

you might include normalizing cycle only when any of the weld also under go normalizing (e..g dished end with weld)

Dear All,

Pl clarify the below.

One of vessel under fabrication will under go the fallowing heat treatments. (Material-516 G 70, shell-63 mm, dish end -75mm, dish end in one piece only)

• Dishends Normalising-2 cycle.
• PWHT for whole vessel.

Now shall I need to do all three heat treatment cycles to qualify WPS?

OR

Only two normalising cycles are enough?

Regards,

Venkatramulu
