Corrugated Steel Pipe
 Over 100 years ago, James Watson was granted a patent for
corrugated steel pipe (CSP). Since then, CSP has proven to be a mainstay
of the construction industry. It is among the top-rated products for
infrastructure because it withstands the stress of heavy traffic and
unstable foundations better than most construction materials.
In drainage systems, CSP provides years of durability, making it the
material of choice for culverts, storm sewers, spillways, subdrains,
underpasses, conveyer conduits, service tunnels, detention chambers and
recharge systems. The strength and integrity of soil/steel structures
are almost unlimited.
Corrugated steel pipe is available in various shapes and sizes to
meet several kinds of drainage, sewer and transportation needs. It can
be fabricated to exact specifications. The round pipe standard size
ranges from 6 in. to 26 ft. (150 mm to 8 m) and is available in larger
sizes. Pipe arches, long span structural plate arches, and box culverts
are available in many combinations of rises and spans. Pipe arches have
been used with and without stiffeners for spans of 80 ft. (25m) and 110
ft. (33.5 m), respectively.
Research shows that CSP generally provides outstanding soil side
durability. With proper coating and/or invert paving, CSP can provide a
service life of 50-100 years for a wide range of environments and
applications. Maintenance
costs can be effectively controlled through modern structural and
durability design criteria.
