Processutrustning

 This document specifies the selection criteria and minimum requirements for selecting coatings for pressurized service within process vessels. This is given for the following: — key factors influencing coating selection, — generic composition of test liquids which can be used as references when evaluating supporting testing evidence for coatings, — principal test methods to be used as evidence of performance when selecting suitable coatings, — ensuring that supporting evidence used in evaluating coatings is relevant to the potential end use. This document refers to types of coatings that are generally available, with properties that are known and documented. It also allows other materials to be evaluated and qualified for use. This document is to be used for process vessels coated at the new construction phase. It is intended to be used only where the coating is applied directly to the substrate. This document does not cover requirements related to metallic coatings nor weld overlay materials.
