Steel-Lined, Polymer-Coated CMP Pipe for Difficult Situations

Smooth Cor™ consists of a standard corrugated steel pipe as its structural exterior shell and includes a hydraulically smooth steel liner. Both the interior liner and exterior shell are coated on both sides with a polymer coating. This combination makes Smooth Cor Pipe the economical and performance alternative to concrete in difficult situations such as weak soils, poor subsurface drainage conditions, steep slopes, and high fills.

Smooth Cor can be fabricated into any type of structure including tees, elbows, laterals, catch basins, manifolds and reducers. Pre-fabricated fittings are more economical and have superior hydraulic characteristics when compared to concrete structures.

Smooth Cor should be specified as an alternative under normal site conditions and specified exclusively under very difficult situations that demand the strength of CMP with positive joints and a hydraulically efficient smooth liner.

Smooth Cor Pipe Features and Benefits

FEATURES BENEFITS

Smooth steel liner

Manning’s “n” of 0.012, outperforms reinforced concrete pipe

Corrugated steel shell

Provides structural strength to outperform rigid pipe

Polymer coating

Protects against abrasion and corrosion to provide a service life of 100 + years

High beam strength

Superior to concrete pipe in many difficult situations such as weak soils, poor subsurface drainage conditions, steep slopes and high fills

Lightweight

Easier and less expensive to install than concrete pipe

Smooth Cor Pipe Properties

  • Lined with either 18 or 20 gage steel
  • Diameters ranging from 18” to 66” in 2 2/3 x 1/2 corrugation
  • Diameters ranging from 48” to  126” in 3 x 1 corrugation
  • Standards lengths are 20’- 40’

Smooth Cor Pipe Shapes

  • Full Round – recommended for most applications.
  • Pipe-Arch – used in limited headroom conditions. The low, wide pipe-arch design distributes the flow area horizontally, providing hydraulic capacity without lowering the grade.
