Abstract
A low profile pipe connection improves process performance or substantially reduces reload time for partitioned beds of particulate material separated by distribution/collection grids. This invention is a multi-sectored grid arrangement that connects piping from an intermediate point on each grid sector with a central or peripheral fluid distribution point through the use of a low profile connection. The reduction in diameter of the low profile connection over the usual flanged connection is substantial.
