Eddy Current DFT Gauge - non-destructive testing instrument used to measure the Dry Film thickness of a non-conductive film on a non- conductive substrate
Non-conductive substrates - aluminum, brass, stainless steel
Eddy Current DFT Gauge - AKA non-ferrous gauge
UT Gauge - non-destructive testing instrument uses pulse Echo to measure coating thickness on a non-metal substrate
Non-metal Substrates - plastic, wood, concrete, wall board
ASTM D 6132 - standard for measuring coating thickness on substrate by ultrasonic thickness gauge
NACE standards - voluntary standards using consensus procedures
localized corrosion - more frequently causes the need for unplanned maintenance
40% relative humidity - corrosion virtually ceases
Anode - negative posts
Anode - the less noble region also where reduction occurs
Cathode - the more noble region
Cathode - positive post
-0.85 - minimum voltage required for cathodic protection
Waterjetting - standards are intended to be similar to the degree of air blast
grades of flash rust - light, moderate, and heavy
2 1/2 X maximum operational strength - UHP an HP quipment must be rated of a burst strength
Low Pressure Water Cleaning - Pressures under 5,000 psi
High Pressure Water Cleaning - Pressures 5,000 - 10,000 psi
High Pressure Waterjetting - Pressures 10,000 - 20,000 psi
Ultra High Pressure Waterjetting - Pressures above 30,000 psi
ASTM D 4541 - test method uses a portable adhesion tester capable of applying a concentric load and counter load to a single surface so coatings with only one side accessed can be tested
Acidic - ph less than 7
Neutral ph - ph is equal to7
Alkaline - ph is greater than 7
Life cycle of Coating System (Steel) - depends significantly on the quality of the surface preparation
NACE Coating Inspector Level 2 - Certified - Person is qualified to perform advanced coating inspections using both nondestructive and destructive techniques and instrumentation.
Passivation - production of a tightly adherent layer formed from the corrosion product
Oxidation and Reduction - always occur together; there is never just oxidation or just reduction [Show Less]
