Welding X52 material to A333 grade 6 Piping

[FIF99]

Hi,

Anybody having experience with WPS/PQR's for welding heavy wall piping (NPS 2"-14,2mm) in material equivalent to API 5L-X52 (St.52.3) to material ASTM A333-6 / A420-WPL6 / A350-LF2 Class 1.

Material group as per ASME B31.3 for X52 is S-1 and for A333-6 it is P-1.

Any other issues to take care with other than that of a max. carbon content of 0.23% and CE max. 0.43%?

Thanks for any help.

Regards.
FKE
