  AMERICAN Ductile Iron Pipe Recognized As A SMaRT Certified Product For Sustainability


Water and wastewater utilities looking for ways to further extend the life of their pipe have a new tool – AMERICAN Zinc, an advancement in corrosion control for iron pipe. Zinc has proven to extend the life of iron pipe and protects millions of feet of cast and ductile iron pipe in corrosive environments around the world.

The American−Darling Mark 73−5 hydrant is rated at 250 psig and is seat tested at 500 psig. This hydrant meets or exceeds all requirements of AWWA C502 for dry-barrel hydrants. The all-bronze seat and bronze drain ring assure that the Mark 73-5 hydrant is easily repaired by just one person. The epoxy-primed and polyurethane top-coat system on the external surfaces on the upper barrel of the AMERICAN Mark 73-5 fire hydrant provides a durable, high-gloss finish that, under normal conditions, should continue to look good for years without repainting.

  • Pipe Resiliency In Harsh Environments

    A combination of metallized arc-sprayed zinc coating — with a finishing layer topcoat and V-Bio enhanced polyethylene encasement with an anti-microbial compound and a volatile corrosion inhibitor — uniquely protects pipes in the most aggressive soils.

  • Evolving Advantages For Water Distribution Infrastructure

    With a tried-and-true technology like ductile iron pipe, it can be easy to overlook some of the newer developments that are keeping this long-term water-industry standard relevant in the face of challenging operations. In this conversation with Maury Gaston of American Ductile Iron Pipe/American Spiral Weld and Derek Scott of American Flow Control, the benefits of new opportunities abound.


  • All-Terrain Ductile Iron Pipe Delivers For Washington County, Utah

    With its red rock and steep cliffs and canyons, the terrain of Washington County, Utah, is breathtaking and is one of the most geologically diverse areas in the world. This location, however, also lends itself to drought. It is the driest county in the state, receiving only an estimated eight inches of rainfall a year in its major population centers. Compare this to other U.S. counties that receive an average of 39 inches of rainfall annually. 

  • Why Material Selection Matters

    The Tri-County Water Authority (TCWA) was formed in 1991 as a not-for-profit water utility serving portions of Jackson, Cass and Bates counties, Missouri. When the system was first established, about half of the pipe installed were ductile iron and half were plastic PVC. Today, the authority’s 120 miles of pipe are approximately 75% ductile iron and 25% plastic PVC.

  • AMERICAN® Products Support Paulding County’s 20-Year Effort To Ensure Safe, Sustainable Drinking Water

    More than 13 miles of AMERICAN ductile iron pipe and nearly two dozen AMERICAN Flow Control® resilient wedge gate valves with Flex-Ring® ends are playing an important role in providing safe, affordable drinking water to fast-growing Paulding County, Georgia, one of the only counties in the metro-Atlanta region without an independent water supply.

  • American SpiralWeld Supports The Road To Local And Regional Progress In South Carolina

    When the Hugh K. Leatherman Sr. Terminal opens in North Charleston in 2021, container traffic traveling to and from it will use the new Port Access Road, a direct route from I-26 that will reduce the need for commercial trucks to use local roads. Supporting the mainline road’s foundation piers will be South Carolina made spiral-welded structural steel pipe installed as vertical piles driven 60 to 90 feet into the ground. Spiral-welded steel will also be used in the subfoundations of associated new bridges and roads.

  • Setting A Precedent: American And Others Work To Ensure Oregon Water System Meets Rigorous Seismic Safety Standards

    Most agree that Oregon, with its breathtaking mountains and rugged coastline, is a scenic wonder. Yet the geologic forces that make it so spectacular also make it one of the most earthquake-prone spots in the country.

  • SPRWS Upgrades To Corrosion-Resistant Zinc-Coated Ductile Iron Water Main

    It is no secret that a large portion of the drinking water infrastructure in the United States is near or past its intended design life. Our nation’s water infrastructure needs an overhaul, and the cost of doing so is climbing rapidly. The American Society of Civil Engineering’s 2017 Infrastructure Report Card graded the nation’s drinking water infrastructure a D. According to the American Water Works Association, an estimated $1 trillion is necessary to maintain and expand drinking water service to meet demands over the next 25 years.

  • The Design Decision Model® Reveals Longevity Of Ductile Iron Pipe

    Earlier this year, Maury D. Gaston, manager of Marketing Services for AMERICAN Ductile Iron Pipe and chairman of the Alabama Iron and Steel Council, presented at the 2019 NACE Corrosion Conference on Metallized Arc-Sprayed Zinc Coated Ductile Iron Pipe.

  • It Runs Through A River: 1.7 Miles Of AMERICAN Products Help Deliver Water In North Alabama

    Six million gallons of water per day (MGD) sounds like a lot of water, and it is, but it wasn’t enough to meet Limestone County’s projected demands for drinking water. Around 1,000 customers were being added each year, and a number of inquiries had been made about increased industrial development.

  • Bright Lights, Running Water: AMERICAN Flow Control Valves Ensure Flexibility On Las Vegas Strip

    Running under the lights and sounds of the Las Vegas Strip are miles and miles of water pipelines. Managing and maintaining the main supply of water to this area is a Rate of Flow Control Station (ROFCS) operated by the Southern Nevada Water Authority (SNWA). This ROFCS alone has the ability to deliver up to 180 million gallons of water a day.

  • First-Time Customer Praises AMERICAN Flow Control’s Valves With ALPHA Ends For Quick Install And Time Saved

    The estimated 100-year-old small diameter water mains coming westward out of Manning, South Carolina, were beginning to show their age. So when it was determined the South Carolina Department of Transportation would soon be resurfacing SC Highway 261, the city knew it was the optimal time to replace these aging smaller mains. The mains serviced the Clarendon County Courthouse, City Hall, the elementary, middle and high schools and about 60 businesses along SC Highway 261.
