When choosing an appropriate utility piping material for your water or wastewater project, there is so much more to consider than just the purchase price alone. This comparison between two popular piping materials – HDPE and Ductile iron pipe – demonstrates the need for more than just a cursory review or habitual choice. At McWane Ductile, we are always available to run through the matrix with you. Some installations or conditions do favor alternate materials, yet it’s hardly ever a cut-and-dried deal. Let’s take a closer look to find out why.
Gaskets Are Great
Rubber gaskets are the reliable workhorse of any Ductile iron pipe (DI pipe) joint. They provide long-lasting flexibility and a watertight seal against internal pressures upwards of 1,000 psi.
What they don’t do, however, is bind the joint longitudinally against such forces. In fact, without assistance from other variables, a push-on or mechanical joint of any diameter would calmly separate lengthwise against pressures as low as 50 psi.
Nowadays, it seems more and more municipalities and utilities are requiring contractors to hire someone to pressure wash Protecto 401TM -lined ductile iron pipe before they will accept the pipe into their system.
Over the past several years, you may have heard a lot about applying zinc to your Ductile iron pipe as either a means of corrosion protection or as an added product which will extend the life of DI pipe in a non-corrosive environment. In this blog, we will look a bit closer at the origin of the practice and effectiveness of using zinc for external corrosion protection.
Every day around the world, Ductile iron pipe is being installed and used to provide individuals and families the luxury of having quick and easy access to clean water. From the manufacture to the contractor, the end goal is the same; that each pipe joint form a watertight seal after proper assembly.
A displaced or rolled gasket creating water loss in a ductile iron pipeline is one of the most common errors that occurs during joint assembly. Using the resources and experience of McWane Ductile’s long history of manufacturing iron pipe, this blog will provide some helpful tips regarding how to avoid this costly mistake when installing push-on joint pipe.
Radial Welded-on Outlets, Tangential Outlets, Bossed Outlets, and Thread-O-Lets. Have you ever been involved in a project utilizing one of the various pipe outlet configurations? If so, you are likely aware of the special care these products require. If you haven’t been involved in a project requiring outlet piping, then within this blog we will explain the types of outlets available and the importance of the unloading, storage, and installation process.
Ductile Iron (DI pipe) was first used in the United States as early as 1950's. Since iron pipe was one of the earliest pipe materials to be used in modern water works and wastewater systems, most early fittings and couplings were designed to be used on Grey Cast and then Ductile iron pipe.
So, connecting “other” piping material to DI pipe is very straightforward on the Ductile pipe side of the fitting. The most important item to consider is on the other material side of the connection.
The normal, stocking item for Ductile iron pipe products is lined and coated with a sealcoat that comes in your choice of black. Many water professionals wonder about the purpose of this coating, or paint, that gives Ductile iron pipe it’s familiar appearance. In this article we offer some explanation and history behind the application and advancement of the sealcoat.
Gaskets are a critical component in your ductile iron piping system. To get the full benefit of your gaskets, they need to be stored in a manner that minimizes deterioration. We don’t always work in favorable conditions, so no matter if you are in the field or in a warehouse, utilizing the best storage practices and locations are key to the performance and the effective lifetime of your gaskets.
In this article, we will cover some guidelines on how to store and care for your gaskets. We will cover the “what to do” as well as the equally important,”what not to do.”
It is pretty much a daily occurrence here at McWane Ductile for our sales staff to receive price requests on a variety of ductile iron pipe (DI pipe) products. Usually this request is for a specific project, but occasionally design engineers will also ask for “budget pricing” for future underground utility projects. This is typically a pretty simple task, but to provide the most accurate and cost-effective pricing, there are a few items that must be addressed that will ultimately determine the final cost to the customer. This article will review some of those variables that determine the final pricing for your DI pipe needs.
