ULTRA FLO (Spiral Rib Pipe)

CONTECH ULTRA FLO® Pipe has over a decade of proven performance on municipal, transportation, airport, shopping center, and residential development storm sewer projects. ULTRA FLO’s rapid acceptance is based on its Manning’s “n” of 0.012, structural strength, and faster and more cost-effective installation than concrete pipe. ULTRA FLO is available in a wide variety of materials to meet environmental and service life requirements.

 
Product Highlights: ULTRA FLO (Spiral Rib Pipe)
  • Exterior box corrugations permit hydraulic flow equivalent to concrete pipe
  • Corrugations provide structural properties needed to manage HS 20 and HS 25 vehicular loadings
  • Available in diameters from 18"-102"
  • Hydraulically equivalent to reinforced concrete pipe
  • Smooth interior surface and longer lengths result in fewer joints
  • Hydraulically efficient prefabricated junctions: elbows, manholes, and catch basins
  • Light weight and long lengths mean less settlement than heavier pipes
