Large Diameter Pipe Applications

Industrial piping systems

Made of high-density polyethylene, our Large Diameter HDPE Pipelines are durable, chemical and corrosion resistant. They’re ideal for industrial applications—requiring no cathodic protection, internal linings or external wraps, and ensuring a long-lasting pipeline with little to no maintenance.

HDPE pipe Wastewater

Wastewater conveyance and treatment

Large diameter HDPE pipe has more than proven its value in wastewater related projects due to its resistance to H2S corrosion, leak-free joints and cost effectiveness. ISCO is unique in its position as the leading distributor for multiple high-quality manufacturers, allowing us to advise and assist our customers on the best products to meet their needs.

Culverts and culvert relining

Culverts across North America are corroding at an alarming rate. Many, on the verge of collapse, creating dangerous conditions. Departments of Transportation (DOT) and other agencies responsible for the country’s roads turn to ISCO's Snap-Tite® Large Diameter Lining System to repair and replace deteriorating culverts. Our Snap-Tite product is a cost-effective, no-dig solution with field-tested benefits.

Storm water conveyance and retention

ISCO’s storm water conveyance pipes provide cost-effective, corrosion resistant and long-term service to clients. Our HDPE pipes are easy to fabricate and less expensive than cement based products. ISCO specializes in designing storm water conveyance systems that will last longer than the buildings built over them.

Irrigation and hydroelectric penstocks

Water and energy are critical components of our economic health as well as our ability to produce the food we need while protecting our environment. Irrigation districts, small hydro producers and municipalities use large diameter HDPE pipe for their massive water and energy transfer projects, often because it's a more environmentally sound solution than metal or concrete piping.

Manholes, tanks and structures

Our HDPE tank and structure design, combined with the benefits HDPE, has been successful in many different applications. Our HDPE manhole products are custom-built to meet specific site requirements as well as provide a long service life. ISCO's versatile design philosophy allows us to offer virtually limitless design options for manholes, tanks, geothermal vaults, and other structures.

Large Diameter Fusion Machine

McElroy Talon™ 2000

ISCO is the only industry partner to own two of McElroy's biggest machines to date, the Talon™ 2000.

The Talon brings a revolutionary way to fuse large-diameter pipe that is in growing demand to replace aging infrastructures and increase capacity for a variety of applications. McElroy's Talon features a self-propelled vehicle capable of safely lifting pipe from the ground, positioning it to be fused and moved from one joint to the next down the pipeline. It features a quick-action facer and an electric-powered indexer to accurately and safely position the heater and facer into the fusion machine.
