Ductile Iron Pipe - Fact or Fiction?
01/18/2020 In Products TechnicalMcWane Ductile is committed to offering educational resources based upon sound engineering data to our clients and potential clients. One of these resources includes banners that display certain information about our product.
While attending a recent conference, we were challenged on the information these banners contained. In fact, one unknown individual walked by the booth and shouted, “Lies... that information is lies!” without the courtesy of stopping to discuss why he felt that way or what exactly was his objection.

What is Tuberculation and Why Did it Happen in Iron Pipe?
04/13/2023 In Products TechnicalIn years past, gray cast iron pipe was originally sold with no lining or coating on the pipe's interior. After many years of study, it became apparent that the inside of cast iron pipe might be affected by certain types of water. In this Iron Strong Blog, we will describe tuberculation, why it happened in older iron pipe, and the modern solution for tuberculation.

Horizontal Directional Drilling With Ductile Iron Pipe
01/27/2020 In Installation TechnicalHave 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.

Why Are the AWWA Standards Important to Ductile Iron Pipe?
10/14/2022 In Products TechnicalHave you ever wondered what’s behind the AWWA standards? What do they mean? And why do we need them? They’re listed all the time in specifications, mysterious numbers on plans. Have you ever reviewed them to know why they are important for working with Ductile iron pipe (DI pipe)? In this Iron Strong Blog, we will briefly cover some of the applicable standards for DI pipe and how they help you complete your job safely, successfully, and on time.

How Do the Trench and Backfill Protect the Pipe?
12/02/2021 In Installation TechnicalUtility pipelines provide for some of the most basic needs within our society. Essential services, such as supplying potable drinking water to our homes and businesses or sending wastewater away, are possible because of a network of buried pipelines. Whatever pipeline materials are used, they are expected to meet minimum service qualities such as withstanding leakage. This resiliency to leakage eliminates waste of our precious drinking water and prevents polluted soils from wastewater in the pipeline's proximity.

Why is Depth of Cover Important When Installing Ductile Iron Pipe?
12/20/2019 In Installation TechnicalWithin this article, we will discuss Depth of Cover and the key factors to consider when selecting the type of trench (or laying condition) for your application. We’ll also discuss why it is important to choose the correct trench application, not only for today, but for future adjustments or improvements that are planned for the surrounding area where the pipeline is being installed.

What Are The Benefits of DI Pipe vs. Concrete Cylinder Pipe?
09/02/2020 In ProductsPrestressed Concrete Cylinder Pipe (PCCP) has been used in water and wastewater applications for nearly 80 years. The thought process behind PCCP was sound, in that it would combine concrete's high compressive strength with steel's high tensile strength. However, like many products, PCCP has continued to fall short in the following years in many comparative categories to Ductile iron.

What is the Maximum Direct Tap Size for Ductile Iron Pipe?
09/10/2020 In Installation TechnicalWith Ductile iron pipe (DI pipe), typical service taps can be installed directly into the wall of the pipe, which is called “direct tapping.” The ability to use direct tapping eliminates the need for tapping saddles. And the ease at which DI pipe can be "hot tapped" helps avoid the issue of unhappy consumers because their service and pressure are not impacted by the addition of a new tap. The waterworks community frequently asks us, “How big of a tap will DI pipe allow?” The simple, most conservative response, not having interrogated the user as to their DI pipeline particulars, would be as follows:
