Max Flow spiral rib pipe combines all of the most essential elements of a storm drain system: hydraulic efficiency, structural integrity, durability, & economics.  Max Flow is one product that should be included in all storm drain projects.

Hydraulics
Max Flow Spiral Rib Pipe is hydraulically equivalent to other smooth interior pipe products. The designer can now perform one hydraulic analysis and specify competitive products. Hydraulic tests confirm that the Mannings n is 0.012 for Max Flow. Long pipe joints, prefabricated junctions and a smooth interior constitutes Max Flow Spiral Rib Pipe as the hydraulically premier product available.

Economy
Max Flow Spiral Rib Pipe is a corrugated metal pipe product. All of the advantages attributable to metal pipe applies to Max Flow. A comparison of the pipe's physical qualities are the first advantages usually distinguished between the competing products. The standard joint is twenty feet in length compared to eight feet for Reinforced Concrete Pipe. The standard joint weighs approximately 10% to 20% than that of the same size RCP. Typically the actual material cost is lower than that of RCP or plastic pipe. If the prefabricated fittings for manholes, inlets, outlets and elbows are all factored in the cost savings for the material can be substantial.
