CSP SmoothWall pipe is an interior smooth wall pipe fabricated from a base product of steel with various coatings to meet the demands of various environmental conditions.

It is manufactured by a continuous interlocking spiral seam with external 19mm x 19mm square shaped stiffener ribs on 190mm centers. This combination of design and manufacturing produces a hydraulically smooth interior wall pipe with Manning’s “n” equivalent to the standard 0.013 used in storm sewer design.

CSP SmoothWall is the ideal water management solution with significant advantages over other drainage products. This unique drainage product offers a wider variety of sizes, shapes, thicknesses, fittings, lengths, and special coatings.
