Choosing the Right Pipe

There are numerous options available when selecting conduit and innerduct for underground utilities applications. As such, it is important to choose the right pipe for your needs. The following is a brief overview of some of the more common and popular conduit and innerduct products on the market. HDPE pipe (high density polyethylene) is strong, lightweight, and flexible. It is often used as conduit or innerduct in electrical, utilities, and telecommunications applications. This type of pipe easily bends around obstacles, can be heat-fused to prevent leaks, and can last up to 50 years or more. HDPE pipe is also corrosion, abrasion, and impact resistant, and is generally less expensive than metal pipe. Rigid PVC conduit is flexible and strong, and is popular for electrical, utilities, and telecommunications projects. Generally cut and shipped in short, straight sections, it is easier to handle than reeled conduit. This pipe is corrosion, abrasion, and tuberculation resistant, and won’t ovalize or deform. Rigid PVC conduit accepts standard elbows and fittings, and can be joined by hand without special fusion equipment, making it easier to install. Split PVC conduit is impact and ultraviolet resistant, making it ideal for fiber optics and cable installations. Sections snap together for fast, easy installation, and allows for repairing of lines without cutting cables or connections. Cable in conduit (CIC) is an ideal choice if the exact length of cable or conduit is known prior to installation. Cable is placed directly into the conduit, making it unnecessary to pull wire after the conduit has been placed. This leads to less waste of wire and duct, and protects wire from damage that could be caused during the installation process. All products above are available from Chapman Electric Supply, Inc.
