The cast aluminum line of Smart Elbow deflection elbows is now offered in tube and pipe sizes from 1.5 in. (3.8 cm) up to 12 in. (30.5 cm) in diameter. Engineered for dilute-phase and dense-phase pneumatic conveying systems, the components prevent portland cement, cementitious materials, sand, aggregate and other abrasives from impacting the elbow wall, curtailing wear, failure and downtime.
The elbows feature a spherical chamber that protrudes partially beyond the desired 90- or 45-degree pathway, which causes a ball of pellets suspended in air to rotate, gently deflecting incoming material around the bend without impacting the wall or generating heat. Other deflection elbows, offered in varying size ranges up to 18 in. (45.7 cm), are available in cast iron, carbon steel, stainless steel and specialized alloys.
According to the manufacturer, conventional sweep and “plugged tee” elbows are typically replaced with deflection models to ensure product quality, allow directional changes in restricted spaces and prevent unscheduled system shutdowns due to elbow maintenance or repair. — HammerTek Corp., Bethlehem, Pa., 610/814-2273; www.hammertek.com
