Subject: [MW:8129] Welded Elbows
Dear All,
I have received an Elbow from my one of the supplier of size 12'' NB
of carbon steel material. I have a doubt that these Elbows are EFW
elbows , but my order was of seamless Elbows. Can anyone please tell
me how to check whether the Elbows are seamless or welded. I know by
macro examination it is possible to check, but I don`t want to cut the
sample piece as if they been found welded I will returns the Elbows
to supplier.
Please Help!!!!
