Coatings System Guide

NORSOK Coating System 1

Pre-qualification required

For structural steel and exteriors of equipment, vessels, piping & valves (not insulated) in a pre-qualified coatings system,

the approved topcoat may be substituted by another pre-qualified topcoat provided the intermediate is the same and the

DFT of the topcoats are equal.
