ULTRA FLO, a CMP 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 either aluminum or steel with a variety of coatings such as, Aluminized Steel Type 2 (ALT2), polymer coated, and aluminum 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.
