Hello,

Anyone have any experience with Article F-3? Is a different WPS/PQR required for each heat exchanger , example square vs triangular tube layout?

Any feedback would be welcomed.

Hi, Kellie,

what is the Addenda you are refering to, Add 06 has made big changes
now:
!"The weld dimensions and weld detail, and joint preparation,
if used, shall comply with the details included in
the Welding Procedure Specification."

It is not required to re-qualify for every HX.
