As the name suggests, Long-Span pipe can extend over distances with fewer supports than conventional Ductile iron pipe (DI pipe). In standard 18-foot lengths of DI pipe, a minimum of one support is required within 2-feet of the Bell for each length of pipe. When using Long-Span pipe, distances of 27-foot up to 45-foot and longer can be achieved with support only at the Bell ends.
One question we often receive in the field is, "Can you use Ductile iron pipe (DI pipe) when running hot water or steam through pipe?" The answer to that question is YES, but there are several factors you must consider. For this Iron Strong Blog, we are going to look at these factors to help determine what products are needed for each application.
Recently, there have been multiple unsuccessful attempts by plastic pipe manufacturers and their trade associations to have legislation passed, mostly on the state level, requiring utilities to specify plastic pipes on their projects.
This legislation is a subject worth exploring deeper as it is being promoted by supporters of plastic and their lobbyists as a fiscally responsible requirement. Still, it provides no consideration for the many variables required in material selection or pipeline design; all are completely ignored in the proposed legislation which would ultimately be an "initial price only" comparison.
Every summer, I go backpacking with my family into the Uinta Mountains of Utah. The Uinta mountain range is enormous, very remote, and extremely beautiful. One of the most scenic areas in the entire range is called Red Castle. In this area of the Uintas rises a towering red monolith with peaks that reach straight into the sky, hence the name. Getting there requires a grueling 10-mile trek, but the beauty and serenity are well worth the effort...
I have been on the road for nearly 20 years, talked with numerous contractors and distributors during that time, and there is a common question that I often get asked, "Why do Ductile iron pipe lengths vary?"
The American Water Works Association (AWWA) is the premier trade association representing the drinking water industry in the United States. Through its network of paid professionals and volunteers throughout the country, AWWA has provided the drinking water industry with standards for water system operations as well as valuable research on countless subjects for many decades.
In today’s construction world, things are getting more and more technical and precise. As the waterworks industry evolved over the last 100 years, our understanding of installation processes has as well, specifically concerning stray currents emitted in the ground from steel gas or oil pipeline’s cathodic protection system and how they might influence the corrosion of adjacent Ductile iron (DI) pipelines.
Just as we start to feel that spring is just around the corner, Mother Nature reminds us that we are still in the midst of winter and warmer weather may still be days away. Lower temperatures are great for skiing, sledding, and hot beverages by the fire. However, in some parts of the country, a lower reading on the thermometer means trouble for our water lines.
In extremely cold weather, the water in our pipelines can freeze, cutting off supply to our homes and businesses. This inconvenient problem can be remedied in Ductile iron pipelines through the process of electrical thawing

Have you ever heard the saying, “To the man who only has a hammer in the tool kit, every problem looks like a nail? (Abraham Maslow)” In the water utility industry, some folks may feel this way when faced with a pipeline installation that must circumvent natural or humanmade obstacles, especially water crossings. So, if going around or above is not an option, then what? How about below?
In today’s modern world, there are more tools available in the water pipeline construction toolkit such as the Open Trench Method, the Pier Supported System, and Horizontal Directional Drilling or HDD. In this blog, we’ll discuss the benefits of using Ductile iron pipe (DI pipe) for HDD and provide some considerations and tips for your pipeline installation.
