Dear All,

   I saw in some projects that the pipes up to 24" were semless (exp. A335-P11) and for upper sizes (28", 30", ...) the welded pipes (exp. A691. Gr22) were used.

   1- Do we have any Code and Standard limitation for this matter?

   2- If there is another reason for this matter, would you pls inform me aboout the possible references?

   Thanks,

   M.Orojlu
