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 contamination of the contents. Discontinuities in the film can result in undercutting corrosion of the substrate, and the integrity of …

Introduction/Background Surface profile is defined as a measurement of the maximum peak-to-valley depth created by abrasive impingement against a surface during abrasive blast cleaning operations, or by an impact-type power tool. During abrasive blast cleaning, the mass of the abrasive and the velocity of the abrasive movement created by compressed air generates kinetic energy (the …
