Abstract
An elbow connection for pneumatic conveying systems is provided. The elbow has an inlet opening, an outlet opening and a curved area of short radius extending therebetween. The section of the elbow between the inlet and outlet openings has a cross-sectional area that is substantially greater, at least 1.5:1, than the cross-sectional area of the inlet and outlet openings to reduce the wear of the elbow wall caused by the material conveyed therein.
