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.
Bridge crossings, like many projects, can go extremely well with the proper upfront considerations. We will discuss the benefits of utilizing TR Flex® Ductile Iron Pipe, and take a look at key topics involved in completing bridge crossing projects.
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.
How often have we heard a developer tell a utility they simply can’t afford to install Ductile iron pipe (DI Pipe) for a planned subdivision because it’s too expensive. After all, the developer is providing the water and wastewater mains for free, transferring ownership to the local utility usually after one year.
Forty miles north of Bangor, Maine, at the confluence of the Piscataquis, Pleasant and Sebec Rivers, is the town of Milo Maine, a charming enclave founded in 1802. The early history of Milo was dominated by iron works and railroads where it soon became home to the second largest railroad car and repair facility in the New England territory at that time.
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.

It is very common to get certain questions from our customers regarding the interchangeability of push-on or compression type gaskets that are typically supplied with Ductile iron pipe. These questions are usually easy to answer in a very definitive manner, but there are some exceptions. In this edition of Iron Strong, we will address the three most common questions about gaskets and why this can sometimes be confusing to our customers.
