  • How Does Ductile Iron Pipe Increase Energy Savings for a Water Utility?

    How Does Ductile Iron Pipe Increase Energy Savings for a Water Utility?

    By John Simpson P.E., ENV SP, NACE CT   11/03/2022  In Products Technical

    Approximately 85% of a utility’s capital investment is underground. Since water and sewer infrastructure plays such a significant role in the total energy consumption of municipalities, more emphasis must be placed on energy savings when selecting pipe materials. This Iron Strong Blog will describe factors that affect energy cost at water utilities and how to save money.

    How Do the Trench and Backfill Protect the Pipe?

    By John Simpson P.E., ENV SP, NACE CT   12/02/2021  In Installation Technical

    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.

    Can a Sure Stop 350® Restrained Joint Gasket Be Used for Horizontal Directional Drilling?

    By John Simpson P.E., ENV SP, NACE CT   10/01/2020  In Installation Products Technical

    Those involved in the construction of water and wastewater pipelines are probably aware of the installation methodology of Horizontal Directional Drilling (HDD). HDD is a trenchless technique that provides an installation alternative offering several benefits over traditional open-cut. HDD can be implemented with minimal disruption to surface activities, requires less working space, and can be performed more quickly than open-cut methods. HDD can be used to install new pipelines or replace existing ones. Also, it can simplify or eliminate certain permitting processes. Although there are currently no national standards regarding HDD installations of municipal underground infrastructure systems, HDD has seen a dramatic increase in recent years and is becoming more common for any pipe material. HDD may be the fastest-growing trenchless construction method today.

    What Is the Maximum Internal Pressure Ductile Iron Pipe Can Handle?

    By John Simpson P.E., ENV SP, NACE CT   05/09/2020  In Technical

    What is the maximum internal pressure Ductile iron pipe (DI pipe) can handle, you ask? The simple truth is it depends entirely upon the size of the pipe and its wall thickness. And within any given DI pipe diameter there can be as many as 12 correct yet different answers, given the wide range of intermingled thickness class and pressure class pipe selections available.

    How to Prevent Stray Current in DI Pipe at Gas Line Crossings

    By John Simpson P.E., ENV SP, NACE CT   03/12/2020  In Installation Technical

    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.

  • Horizontal Directional Drilling With Ductile Iron Pipe

    Horizontal Directional Drilling With Ductile Iron Pipe

    By John Simpson P.E., ENV SP, NACE CT   01/27/2020  In Installation Technical

    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.

    V-Bio® Or Cathodic Protection – An Honest Comparison

    By John Simpson P.E., ENV SP, NACE CT   12/13/2019  In Installation Products Technical

    Odds are you may not be a certified corrosion specialist or an expert in the corrosion field for that matter. Most engineers that are responsible for specifying water projects are not. There are of course engineers who dedicate their entire careers to the subject. The good news is that McWane Ductile is committed to excellence in the corrosion field and provides professionals to assist you with making sound decisions regarding corrosion control.
