    HEL-COR® Corrugated Metal Pipe

    HEL-COR corrugated metal pipe (CMP) is used in drainage, culverts, storm sewers, canals, and stormwater detention applications. HEL-COR is available in a large variety of materials, coatings, and sizes to meet site specific needs, and HEL-COR’s continuous locked seams and annular corrugated ends allow for a variety of standard couplings to be used.

    Why Contech Start a Project
    CMP Pipe for Wind Turbine Foundations and Vertical Shafts

    Contech large-diameter CMP is used as a deep foundation form at the base of the windmill. CMP is placed vertically to act as a form for the poured-in-place concrete foundation.

    CMP for Culverts, Canals and Ditch Enclosures

    Our corrugated metal pipe is the most durable, economic, and widely chosen material for most drainage culverts applications. With a variety of CMP products including helically corrugated HEL-COR® and spiral wound ULTRA FLO®, Contech offers engineers and contractors flexibility in designing drainage solutions to best fit their projects’ exact requirements.

    CMP和PVC管for Pipe Reline

    Lining inadequate or failing structures with corrugated metal material or plastic pipe uses little of the available area, thereby preserving the maximum amount of the original opening. Due to the hydraulic efficiency of Contech products, often a smaller structure provides the same hydraulic capacity as the original because of the low Manning “n” factors of A-2000™ and A2™ Liner PVC pipes and HEL-COR®and ULTRA FLO®CMP. Existing culverts and arches are generally lined with structures of the same shape, though slightly smaller in size. Rectangular openings can be lined with round, elliptical or pipe arch structures. Corrugated metal structures can fit almost any existing shape.

    CMP和PVC管for Rehabilitating Storm, Sanitary Sewers and Small Culverts

    恢复原线排水构筑物与液压有效率cient corrugated steel, aluminum or PVC pipe. ULTRA FLO® and HEL-COR® are available in standard diameters through 120” and 144" respectively. Special diameters are also available in both products. The PVC pipe systems, A-2000™ and A2™ Liner Pipe — used for both drainage structures and sanitary sewers—are available through 36” diameter.

    HEL-COR Pipe Coatings

    • Galvanized Steel - Corrugated galvanized pipe made from steel coated with zinc to extend service life. The most widely used and most economical metallic coating for corrugated steel pipe.
    • Aluminized Steel™ Type 2 - Pipe made from steel that has been hot-dipped in commercially pure aluminum; offers 75 years or more of maintenance free service life.
    • Polymer-Coated - Pipe made from steel with a heavy-gage polymer coating; protects against abrasion and corrosion to provide at least 100 years of service life with a guaranteed 80-years “add-on” according to the2012 Polymer Coated CSP Study performed by the NCSPA.
    • Asphalt Coated - Steel pipe coated with asphalt for prolonged service life; and can also be used to improve hydraulics.

    HEL-COR Pipe Properties

    • Diameter range 12” – 144”
    • Wall thicknesses of 18, 16, 14, 12, 10 and 8 gage
    • Available with helical or annular corrugations
    • 1-1/2” x 1/4” and 2-2/3” x 1/2” corrugations for economical and efficient metal use in small diameters
    • 3” x 1” and 5” x 1” offer high sectional properties in large diameter pipe
    • Standards lengths are 20’- 40’

      HEL-COR Pipe Shapes

      • Full Round - recommended for most applications
      • Pipe –Arch - low, wide pipe-arch design distributes the area horizontally to provide adequate capacity without raising the grade

      Corrugated Metal Pipe for Storm Sewers, Culverts, Small Bridges, and Stormwater Systems

      HEL-COR®helically corrugated metal drainage pipe provides the power to withstand severe environmental conditions and burial depths associated with drainage systems, culverts, storm sewers, and stormwater detention systems.

      HEL-COR service life exceeds 100 years with proper specification that meets all AASHTO and ASTM pipe specifications, and it can handle fill heights in excess of 100 feet.

      A wide choice ofcoatingsincluding galvanized steel, aluminized steel type 2 (ALT2), and polymer-coated steel are available to meet a variety of durability requirements. A variety of wall thicknesses (gages), corrugations, diameters, and pipe section lengths permit a choice of materials to meet specific job site requirements.

      Standard fittings include tees, wyes, elbows, saddle branches, reducers and manifolds for detention systems. Manholes and catch basins can be fabricated to meet specific job requirements.

      HEL-COR is manufactured with continuous locked seams with annular corrugated ends enabling the use of a variety of standard couplings including soil-tightHUGGER® Bands and QUICK STAB® Joints.
