[MW:1148] Presence of laminations in seamless pipes and fittings

Dear All,
 
As per Aramco company specification, Fittings that are re-cut or re-beveled shall have the cut surface examined for laminations before welding.
 
Now my question is
 
1. What are the chances of getting laminations in seamless pipes and fittings that are manufactured from seamless pipes.
 
As per my understanding of this clause, only fittings and pipes that are fabricated from plate should be checked for laminations after cut and re bevelling.
 
Expert comments requested.
 
Thanks and regards
