CSP Arch Pipe

CSP is also available as a pipe arch (flat bottom), when height of fill conditions are limited. The pipe arch distributes the cross sectional area of the pipe horizontally to allow for the limited headroom without any reduction in capacity.

Pipe arches are produced from round corrugated steel pipe by either applying an internal or external pressure to achieve the specified span and rise dimensions.

Planned size and site conditions often impact the shape selected, with strength and economy as additional factors.

A pipe arch can also handle larger volumes of water at lower levels of flow.
