Armtec - Ultra Flo Steel Pipe

Ultra Flo pipe is produced by a continuous spiral seam method. Stiffness is provided by external box-shaped ribs, 19 mm x 19 mm, at 190 mm centres.

Ultra Flo performs as a flexible compression ring under load, redistributing pressure radially into the surrounding high-density soil. The unit pressure at the pipe invert can be as little as one-third of the unit pressure under a rigid pipe in identical loading conditions.

• Fast installation
  Lightweight and long lengths with minimal joints
• Durable
  Available in galvanized steel, aluminized steel, polymer-laminated and aluminum steel to suit environmental conditions
• Nestable pieces
  Efficient shipping for remote locations
• Value
  Lowest installed cost compared to large-diameter concrete storm sewer
• Efficient Hydraulics
  Ultra Flo’s low “n” factor is equivalent to or less than the standard .013 usually used in storm sewer design
• Efficient shipping for remote locations – pieces can be nested
• Lowest installed cost compared to other large diameter storm sewer materials
• Couplers provide mechanical pull-apart resistance – critical in soft soils
• Variety of materials to match design service life to material service life

• Municipal storm sewers, especially in large diameter in long runs
• Highway median drainage
• Industrial storm sewers
• Large diameter culvert slip-lines
• Stormwater detention tanks
