D. SWEEP ELBOWS

Long radius elbows are otherwise known as “sweeps”. In pneumatic conveying, a good rule of thumb
for the radius of the sweep in the conveying line is from 10 to 12 diameters of the tubing . Vacuum line
sweeps can have a shorter radius since only air is normally moving through these. In the section
which specifies sweep elbows, the radius of each sweep is shown. The radius referred to is the radius to
the center line of the tubing bend. Sweep elbows generally have a six inch straight section on each
end of the elbow which is referred to as the “tangents”. In a conveying system, it is desirable to
minimize the number of bends in the conveying line because of the frictional losses which occur as material
travels around the bend and drives against the outside wall of the tube. In terms of equivalent straight length,
each bend is equivalent to approximately 20 feet.

Sweeps of “Sanitary” tubing are included here for use where food and pharmaceutical applications dictate.

Tube bends of up to 90 degrees are readily available in aluminum, stainless and carbon steel. Other
center line radii are available but not shown.
Wall Thickness:
• Schedules 10 and 40 pipe. Other wall thickness on request
