ENGINEERED SOLUTIONS Corrugated Metal Pipe Tomorrow’s Environments Engineered

Contech provides a full range of Corrugated Metal Pipe for severe-to-normal conditions ® Coast-to-coast, engineers and contractors rely on Contech Corrugated Metal Pipe for culverts, storm sewers, small bridges, stormwater detention systems, conduits and windmill foundations. No other type of drainage structure offers the range of structural strength that’s available with Corrugated Metal Pipe—it performs where rigid pipe fails. Contech Engineered Solutions LLC manufactures to repeatable and exacting standards HEL-COR® and ULTRA-FLO® pipe—which has a 0.012 Manning’s “n”—in galvanized,...

HEL-COR® Corrugated Steel Pipe Helically corrugated HEL-COR steel pipe, available in round and pipe-arch shapes, has over 55 years of proven performance. It is manufactured with continuous locked seams with annular corrugated ends to use with soil-tight HUGGER® Bands. Typical applications are culverts, stormwater detention systems, small bridges, conduits and storm sewers. A wide variety of wall thicknesses (gages), corrugations, diameters and pipe section lengths permit a choice of materials to meet specific job site requirements. Durability requirements are addressed by a wide choice of...

CORLIX® Aluminum Pipe Long Service Life … Economical Contech’s CORLIX Aluminum Pipe provides a predictable service life of more than 75 years when installed in the recommended soil/water environment. It is ideal for municipal storm sewers, underground stormwater detention systems or any standard drainage project that must withstand corrosive environments. Economical Lower initial cost begins with CORLIX pipe’s weight. It weighs only 1/35 as much as reinforced concrete. Lighter weight means easier installation. Trench width and depths are reduced due to the smaller outside diameters,...

Storm Sewer Products Installed Cost Savings Millions of feet of ULTRA FLO have been installed in thousands of storm sewer projects nationwide, providing significant cost savings. Because steel ULTRA FLO weighs less than 10% of concrete pipe, handling and installation costs are greatly reduced. Aluminum ULTRA FLO has only /35 the weight of concrete pipe. Lower labor costs also result from fast and easy joining. Contech Quick Stab® joints or ULTRA FLO — smooth interior corrugated storm sewer pipe Manning’s “n” of 0.012 … Equal to Concrete Pipe ULTRA FLO has over 25 years of proven performance...

Smooth Cor™ —steel-lined corrugated steel pipe Manning’s “n” = 0.012 Smooth Cor is a smooth interior corrugated steel pipe. SmoothCor consists of a standard corrugated steel pipe as its structural exterior shell and includes a hydraulically smooth steel liner. The liner is continuously attached to the exterior shell along the lock seam. Both the interior liner and exterior shell are coated on both sides with TRENCHCOAT® polymer coating by Dow Chemical Company. Smooth Cor is also available in pipearch shape. Smooth Cor is covered by AASHTO M36, Type IA, Pipe Arch is Type IIA. Excellent...

Slotted Drain™—intercepts 50% more runoff Contech Slotted Drain is a practical, continuous opening See Variable Height Grate Drawing 1008732 Slope as Required A “H” inlet for the efficient removal of surface water on streets and highways. The grate on a standard 20-foot length of Slotted Drain will intercept up to 50% more runoff than most standard 2’ x 2’ grate inlets. In parking lots, Slotted Drain removes sheet flow without complex multiple grades or water channeling devices like asphalt dikes, berms and Side View curbs. Slotted Drain is fabricated from corrugated steel pipe cut along a...

Pipe Coating Alternatives Galvanized steel pipe Pre-galvanizing is the most widely used and most economical metallic coating for corrugated steel pipe. Pre-galvanizing protects and extends service life. In addition to forming a physical barrier against corrosion, the zinc coating sacrifices itself slowly by galvanic action to protect the base steel. This action continues as long as any zinc remains. The design life of galvanized pipe— installed in a corrosive environment—can be extended by coating the pipe with asphalt. Aluminized Steel™ Type 2 pipe Corrugated pipe is fabricated from steel...

Polymer-Coated Corrugated Steel Pipe 100-Year protection against abrasion and corrosion Service Life Contech Corrugated Steel Pipe with TRENCHCOAT® TRENCHCOAT is available on corrugated steel pipe and heavy-gage polymer coating pipe-arch as well as hydraulically superior products—such offers long-term protection as Smooth Cor and ULTRA FLO. Your local Contech sales representative can provide details on availability. culverts. Even under harsh conditions, TRENCHCOAT protects against abrasion and corrosion to provide at least 100 years of service life. This tough film, bonded to both the...

Aluminum Durability Superior abrasion resistance CORLIX aluminum pipe’s superior abrasion resistance has been proven through years of exposure to wet/dry abrasion-corrosion cycles. In normally abrasive runoffs, aluminum will only peen with minimum metal loss. Superior corrosion resistance CORLIX’s superior corrosion resistance is achieved by a special aluminum clad culvert material. The rugged core alloy 3004- (H32 or H34) is rated as highly corrosion resistant. Then to increase its resistance, the aluminum culvert coil is clad on both sides with alloy 7072, which is anodic to the core...

End Sections Contech End Sections provide an economical, attractive, hydraulically efficient and durable inlet and outlet on culverts and storm sewers. End sections provide protection against erosion and scouring. They improve hydraulic capacity by channeling flow into and out of the pipe efficiently. They are also reusable if lengthening or relocating the drainage structure is necessary. Galvanized End Sections present a clean-cut effect that is aesthetically pleasing. The tapered sides blend with the contour of the slope to increase roadside aesthetics. Compared with concrete headwalls,...
