Have you ever considered how high temperatures impact your choice of piping material for a water system? It might not be something that comes to mind immediately, but it’s an important factor. Water treatment specialists pay close attention to water temperatures because they influence how the water reacts to treatment chemicals. Additionally, water and ground temperatures can significantly affect the performance of certain piping materials, particularly polyvinyl chloride (PVC).
Over the course of my 30+ year career with McWane Ductile, I’ve had the opportunity to be a part of some remarkably interesting and detailed water pipeline projects. Several of these projects have required a partnership between the community, awarding authority, contractor, water works distributor, and material manufacturer to ensure the projects were installed efficiently and correctly. However, few have matched the scale, complexity, and collaborative effort of the Saugus River crossing—part of the massive Belden Bly Bridge Replacement Project in Massachusetts. This project stands out not only for its technical challenges but also for the preparation, planning, and collaboration of key partners that brought it to a successful conclusion. In this #IronStrong Blog, you’ll hear the when, why, who, and how of this complex and intricate Ductile iron pipe (DI pipe) waterway crossing.
The landscapes and environments in which we live are constantly changing, and ensuring that resilient infrastructure is in place to support local communities is a priority for all cities. In regions where natural disasters occur and pose significant threats, such as wildfires and earthquakes, and as seen most recently in areas such as Lahaina, Hawaii, and the Palisades in the Santa Monica Mountains of Los Angeles County, California, Ductile iron pipe (DI pipe) has proven to be a durable and reliable choice for water infrastructure. This article will discuss why selecting the proper material for underground infrastructure is crucial in combating natural disasters and enabling communities to respond more effectively with a reliable source of potable water and vital fire protection.
Selecting the right pipe material is essential for the longevity and success of any water infrastructure project. While Ductile iron pipe (DI pipe) and High-Density Polyethylene (HDPE) each offer distinct benefits, their differences in strength, performance, and long-term cost are significant. This article serves as a refresh of our previously published article in November 2019. It outlines key comparisons to help engineers and specifiers make informed decisions based on project-specific conditions, such as soil type, pressure, and environmental factors.
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.
Utility 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.
Within 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.
In the realm of Ductile iron pipe (DI pipe) joints, standard SBR (Styrene Butadiene) gaskets are the traditional watertight sealing solution. However, did you know these gaskets are not intended for all applications? When dealing with unique jobs, selecting the proper gasket material catering to specific operational demands is essential. There are specialized gaskets, distinct in composition and functionality, that transcend the conventional capabilities of SBR gaskets. Each gasket described below is made for specific purposes based on factors like soil conditions, fluid temperature, or powerful industrial forces. These gaskets utilize modern elastomers to withstand the demands of any given project. In this #IronStrong Blog, we will closely examine each gasket available for your pipeline project.
Today’s modern push-on gaskets are comprised of different types of rubber compounds, and the development of the push-on gasket has proven to be instrumental to the success of the leak-free water and sewer joint. Let's take a closer look at each specialty gasket available on the market today.
Cement-mortar lining for iron pipe has been used for nearly 100 years. The first installation of gray iron pipe with a cement lining was recorded in Savannah, GA in 1922. Todays modern Ductile iron pipe still utilizes cement lining for a safe and reliable means of providing clean drinking water to millions of people every day.
On occasion, however, the cement lining may have incurred some damage in the field. The lining, although very durable, does not have the same resistance to bending stress or impact as the pipe itself. Certainly, the pipe or fitting should be checked for further structural damage, but once determined the affected area is only the cement lining, repairs can be made under the applicable provisions within the ANSI/AWWA C104/A21.4 standard CEMENT-MORTAR LINING FOR DUCTILE IRON PIPE AND FITTINGS.
