Lower Cost Alternative to RCP Storm Sewer Pipe

ULTRA FLO®, a pipe with a smooth interior, is the material of choice for storm sewer applications and a lower cost alternative to reinforced concrete pipe. The smooth interior improves hydraulic capacity (Manning’s “n” = 0.012, equal to concrete pipe) while the exterior box ribs provide structural strength.

ULTRA FLO is available manufactured with a variety of coatings such as, aluminized, polymer-coated, and aluminum material to meet a wide variety of environmental and service life requirements. For projects with limited headroom, ULTRA FLO is available in pipe-arch.

Because ULTRA FLO weighs less than 10% of concrete pipe, handling and installation costs are greatly reduced. Aluminum ULTRA FLO has only 1/35 the weight of concrete pipe.

Lower labor costs also result from fast and easy joining. Contech Quick Stab® joints or coupling bands do not require special skills or tools. Twenty-foot standard lengths mean fewer joints and faster laying.

Shop-fabricated fittings save installation time in the field while providing hydraulically efficient junctions.

ULTRA FLO Pipe Coatings

  • Galvanized Steel - Pipe made from steel coated with zinc to extend service life. The most widely used and most economical metallic coating for corrugated steel pipe.
  • Aluminized Steel Type 2 - Pipe made from steel that has been hot-dipped in commercially pure aluminum; offers 75 years or more of maintenance free service life.
  • Aluminum Alloy – Pipe made with CORLIX® aluminum provides a predictable service life of more than 75 years; ideal for municipal storm sewers, underground stormwater detention systems or any standard drainage project that must withstand corrosive environments.
  • Polymer Coating – Steel pipe with a heavy-gage polymer coating; protects against abrasion and corrosion to provide a service life of 100+.

ULTRA FLO Pipe Properties

  • Diameters 18”-120”
  • Wall thicknesses of 16, 14, 12, and 10 gage
  • 3/4” x 3/4” x 7-1/2” continuous rib corrugation
  • Standards lengths are 20’-40’

ULTRA FLO Pipe Shapes

  • Full Round – recommended for most applications
  • Pipe-Arch – used in limited headroom conditions. The low, wide pipe-arch design distributes the flow area horizontally, providing hydraulic capacity without lowering the grade.
