Test Your Knowledge Series – Surface Preparation Standards for Non-ferrous Metals
Background Most of the SSPC surface preparation standards focus on the preparation of steel, either by abrasive blast cleaning (dry and wet), power tool cleaning, or water jetting. Recognizing that galvanizing, non-ferrous metals, and various types of stainless steel also need to be prepared for painting, SSPC published a standard for brush-off blast cleaning of…

Introduction/Background When applying a coating system to structures such as tanks and pipelines, the primary goal is to apply a continuous film to help prevent corrosion and section loss, and in some cases, to prevent contaminati...
Evaluating Material Loss of Steel Under Protective Coatings in Ma
Over the past 20 years, the U.S. Navy has widely implemented the use of advanced ultra-high-solids (UHS) coatings for the protection of ship tanks and voids to extend the life of tank coatings.1,2,3 The Navy intends these coatings...
Preventing Crevice Corrosion in New and Existing Steel Structures
Steel structures are often fabricated by bolting (or riveting) structural components together. Bolted joints result in multiple crevices between the bolted members and fasteners. These crevices are typically more susceptible to co...
Test Your Knowledge Series – Calculating and Measuring Wet
Introduction/Background Wet film thickness (WFT) is the measured thickness of any applied wet paint that is liquid-based. The WFT is measured to assure that the correct amount of coating is being applied to the surface. &nbs...
