Corrugated Steel Pipe

ImageOver 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.
