Description: concrete and corrugated PE joints. Superior Flow Characteristics Because of the smooth inside wall of Ultra-Rib, a Manning’s coefficient of 0.009 can be used when designing systems using Ultra-Rib pipe. This compares with Manning’s coefficients of up to 0.023 for other materials like clay

Case Study: The Union Pacific Railroad Chooses No-Dig Solution to Reline Old Culvert (.pdf)
in Athens, Texas. J. David Bateman from Union Pacific's bridge department worked with Snap-Tite Representative Trevor Cone to find a solution for the deteriorating CMP. The pipe chosen to line the corroded culvert was a 63-inch OD high-density polyethylene (HDPE) Snap-Tite pipe. The railroad chose to use
