| Abstract Scope |
Surface finishes of gasket and flange facings are widely considered as crucial factors that affect their sealing capability. However, the standards for flanges and gaskets merely characterize and regulate surface textures through the arithmetic height average of the irregularities (Ra) or the average total roughness (Rz) of the surface. Here, we dig deeper into these surface finish effects, to understand not only the role of these average roughness descriptors, but also, influences of kurtosis and skewness as additional parameters to predict gasket sealing capability. To this end, we carried out SEM imaging and confocal microscopy techniques, as well as other analyses, to characterize surface evolution on common A1050 gaskets, and identify factors that affect sealability. |
