CONTECH’s HEL-COR® CL Pipe is a major advance in storm sewer pipe design. It gives you the hydraulic characteristics of concrete pipe, plus an extended service life compared to unlined corrugated pipe, but at a significantly lower installed cost than reinforced concrete pipe. HEL-COR CL is manufactured from high-strength, helically corrugated steel pipe in diameters from 24"-120” and thicknesses from 0.064"-0.168”. The interior of the pipe is lined with a machine-applied, dense high-strength concrete lining to a minimum of 1/8” thickness above the crest of the corrugation in accordance with ASTM A 849. More than 400,000 feet of CONTECH HEL-COR CL Pipe has been installed across the U.S. The list of repeat users continues to grow and includes federal agencies, large cities, small towns, and state departments.
