Study Shows Trenchless Technology Suitable for Longer Pipe Installations

With the advent of new construction technologies comes the need for proven field tests to advance their use. Horizontal directional drilling (HDD) using ductile iron pipe, first introduced in 1994, is a method of installing the pipe underground without digging a trench. With HDD, a gentle arcing bore path is drilled horizontally beneath the surface, then the pipe is joined section by section above ground, and then pulled through.

More Than a Century-Old Pipeline Demonstrates Sustainability of Iron Pipe

Roads and bridges, airports, energy systems – all are types of infrastructure that we depend on daily to bring functionality to our lives. Yet one of these infrastructures, concrete roadway, lasts, on average, just half our lifetime before becoming worn, riddled with potholes and in need of resurfacing. Hidden beneath our feet, however, is a durable product that plays a more vital role than all of these combined: Gray cast iron and ductile iron pipe make up roughly two-thirds of the nation’s water infrastructure, and they often last hundreds of years.
