Shapes and Uses of CMP Pipe

Corrugated steel pipe is available in a wide range of sizes (up to 96 inches and larger), shapes, gages and corrugation profiles to help designers meet both hydraulic and structural conditions at each site. In addition, corrugated steel pipe is available in a range of coatings, including galvanized, aluminized steel Type 2, polymeric and others. Depending on the respective coating selected for the applicable environmental conditions, a service of 100+ years can be designed.

SHAPES AND USES OF CORRUGATED METAL STRUCTURES
Shape   Range of Sizes Common Uses

Notes:
* For equal area or clearance, the round shape is generally more economical and easier to assemble.
