Utah State University study: Snap-Tite’s Hydro-Bell improves flow

A recent independent study conducted by Utah State University determined that Snap-Tite’s inlet control device, the Hydro-Bell, increases hydraulic flow by nearly 30 percent, relative to the flow through a standard square end inlet condition typically found in culvert applications. The device is ideal for flood-prone culvert rehabilitation projects.
Also according to the study, as head pressure increases, the Snap-Tite Hydro-Bell system flow rate also increases. The Hydro-Bell is designed to “snap” onto the standard Snap-Tite culvert lining system’s machined ends – providing a larger, wider intake at the culvert entrance.
Hydraulic flow in short runs of pipe, such as drainage culverts, is often controlled by inlet and/or outlet conditions. It is possible to maximize flow rate by altering the inlet or outlet conditions in the culvert. However, in most cases, the outlet conditions are difficult to alter; but it is possible to modify the inlet condition.
Currently the Hydro-Bell is available in liner sizes from six to 63 inches. However, larger sizes are available on special request. The Hydro-Bell design consists of rounding the inlet with a leading radius, which transitions to a diametrical recess in the interior of the Hydro-Bell structure.
