Dew point is the temperature at whichcondensation occurs. You are the NACE Inspector on a tank lining project where a 50% solids epoxy tank lining is being applied. After application of the 19 coat you notice small blisters in some areas of the applied lining. Your FIRST preferred course of action is to:Document the problem and advise the Contractor and Owner's representative. If a contractor is using a poorly maintained compressor to supply air for abrasive blast cleaning and convent...

All corrosion of iron at normal ambient conditions is an electrochemical process The cathode of a corrosion cell has an opposite electrical polarity to the anode Based on the galvanic series presented in the NACE CIP Level 1 Manual, which three can be used effectively as galvanic anodes for carbon steel? Zinc, aluminum, magnesium A corrosion inhibitor is a substance that, when added to an environment decreases the rate of corrosion A decrease in temperature will generally cause the corro...

CIP Level 1 NACE-CIP1-001 Information - NACE- Coating Inspector Level 1 written ExamThe Coating Inspector Level 1 written exam is designed to assess whether a candidate has the requisite knowledge and skills that a minimally qualified Level 1 Coating Inspector must possess. The 100 multiple-choice questions are based on the Coating Inspector body of knowledge. A candidate should have entry level knowledge of all corrosion, surface preparation, cleanliness, environmental conditions, tes...

Define CorrosionThe deterioration of a substance, usually a metal from a reaction with its environment What is passivation?A layer of oxides formed on the surface of a metal that provides corrosion protection. What is an example of passivation?Stainless Steel What are the elements of a corrosion cell?Anode, Cathode, Metallic Pathway, Electrolyte Describe what happens at the anode.The metal dissolves into the electrolyte What is the function of the electrolyte?Allows the passage of ions ...
