Expansion joints ensure a correct fit every time. There are many different reasons an aerial duct is the better option for you and your business. Some of the purposes for aerial ducts include road and rail crossings, trolley crossings, and water crossings. An aerial conduit application provides an efficient means of supporting cable, which can be replaced easily or allow for adding additional cables without requiring anyone to enter into hazardous or hard-to-reach areas. Another thing to consider in your search for aerial innerduct is UV protection. This sunlight protection is available only in materials with special carbon black pigments because the constant direct exposure to UV radiation significantly shortens the lifetime of unprotected conduit materials.
In addition to our specialty types of aerial duct, we use expansion joints designed primarily for aerial conduit installations. The purpose of this design feature is to absorb thermal expansion and contraction created by temperature changes, which can be present when dealing with above-ground installation.
Cable in Conduit (CIC)
Over 20 years experience makes us an expert in CIC. An electrical cable in conduit is a tube used to protect and route electrical wiring in a building or structure. This protective encasing may be made of metal, plastic, fiber, or fired clay. Most cable in conduits are rigid, but flexible conduit is used for some purposes. Electrical conduits provide excellent protection to enclosed conductors from impact, moisture, and chemical vapors. Varying numbers, sizes, and types of conductors can be pulled into a conduit. This simplifies design and construction compared to multiple runs of cables or the expense of customized running. Wiring systems in buildings may be subject to frequent rewiring for the safety of everyone in the building. Frequent wiring changes are made easier and safer through the use of electrical conduit, as existing conductors can be withdrawn and new conductors installed, without any major disruption to the rest of the wiring.
When installed with proper sealed fittings, a conduit will not permit the flow of flammable gases and vapors, protecting against fire and explosions. Metal and plastic conduit can be bent at the job site to allow for a neat installation process without excessive manufactured fittings.

Think of future goals and save money over time. While Pittsburgh Pipe was founded on steel casing pipe, we are proud to have grown and expanded our offerings to include piping for all industries. Microducts are small ducts that make installing fiber optics easier! Microducts are primarily small in diameter, flexible, or semi-flexible ducts designed to provide clean, continuous, low-friction paths for placing cables that have relatively low pulling tension limits. Bundles of small microducts are installed within the main microduct, protecting the smaller microducts.
Did you know that using Microducts can help you save money in the future simply by thinking of future goals? Whether you’re just starting a project, expanding one, or rehabbing a previous one, microducts are perfect to handle fiber optic projects. From the expansion of the information superhighway, electrical, power, energy, or the communications industry, microducts are a considerable part of that growth and success.
You can count on the Pittsburgh Pipe team to provide a solution for long-term success and safety with our plenum interduct piping with nonmetallic flexibility. For your optical fibers, we offer riser rated innerduct piping that withstands heavy weights, all while being flexible and lightweight enough for dynamic installations. These pipes adhere to industry standards such as UL 2024 and ASTM D 4216. Our other nonmetallic, flexible products include plenum rated interduct, which adheres to UL-(910), Article 880, and UL-2024. These plenum interducts are ideal for projects with pulls of fewer than 1,000 feet and reduce the surface contact of cables that are pulled through the ducts.
Once installed, this piping is buried in the ground, and it’s critical to invest in piping that won’t leak.
We offer a wide variety of choices:
- Wall Thicknesses SDR 11 or SDR 13.5
- Coil Lengths from 100- to 1,000 feet
- Straight Lengths in 20-, 40- or 50 feet
- ASTM Specifications F714, D3035 and D3350
- PE3608 and PE4710
