Sermagaurd and Xylan Coating
Sermagaurd and Xylan Coating
(OP)
Hi all,
As per our purchase order requirement, for Wellhead equipment (Materrial grade AISI 4130), all studs and nuts (Stud: ASTM A193 B7M and Nut: A194 2HM) shall be Sermagard coated. However, our vendor is offering us Xylan coated Studs and Nuts.
They are now justifying that both coating methods are equivalent.
Can we accepte xylan coated studs/nuts in place of Sermagard coated one ??
Regards
