Zinc plate for Bolts and nuts exposed
Zinc plate for Bolts and nuts exposed
(OP)
Hello, everybody.
There is inside Nace MR0175/ISO15156(2):2009; A2.1.5 a mention about the metalic coatings. That is a not acceptable for preventing SSC. For standard we offer the bolts and nuts to attend NAce with Zinc plated. The material is correct with Nace (B7M-2HM). Our intention is not preventing SSC. Could we provide plated or nude bolts and nuts ?

If it is not, why you are referring NACE MR0175. (Off-shore).
It is not recommended for Nude Bolts and Nuts. It should be coated/plated by Zinc-Ni plated or according to
your specs.

Have a look at BS 7371 and Shell ES/313 to have a better idea.
