[MW:18952] Cryogenic plant (Nitrogen generating unit liquid & gas ) Process piping welding with normal ER 308l fillerwire

Dear Sir,

What's problem happen in future?

(1) If wr are using   ER 308L filler wire without carring lateral expansion at -196 in ss 304l process piping in cryogenic (Nitrogen generating) plant  (Liquid/gas  fluid).

(2) If we are using both filler wire ER 308L with lateral expansion (0.38mm ) at -196 degree. & ER 308L without lateral expansion. how to segregate the joints in this case.

regards 

lalit
