  • Why Zinc on Ductile Iron Pipe and What's the Hype?

    Why Zinc on Ductile Iron Pipe and What's the Hype?

      10/10/2019  In Installation Products Technical

    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.

    How Do I Ensure I Have the Proper Size Casing Pipe for My Ductile Iron Carrier Pipe & What Else Might I Need to Know?

    By Gary Gula   10/16/2020  In Installation Technical

    Most people commonly think the answer to this question is relatively simple. “All I need to do is make sure the Inside Diameter of the casing pipe is larger than the outside diameter of my carrier pipe.” While that is a correct answer, it isn’t necessarily the best answer. Within this Iron Strong Blog, we will closely examine what you need to consider when selecting a casing pipe to fit your application.

    The Smoking Gun: Thermal Degradation of Plastic Pipes Linked to Drinking Water Contamination

    By John Johnson, ENV SP, NACE CT   07/30/2021  In Environmental & Safety Products

    As of October 2020, more than 47,000 wildfires have occurred across 36 U.S. states. Drought is a major factor, as a large portion of the West is currently experiencing the most severe level of drought, dubbed “exceptional drought” by the U.S. Drought Monitor. Humans cause the majority of wildfires with negligence such as unattended campfires, discarded cigarettes or arson, followed by natural causes such as unusually long-lasting hot lightning bolts. (U.S. Drought Monitor, 2012)

  • Cyclic Pressures - What's the Difference Between Ductile Iron & PVC and How Do I Accommodate In Pipe Design?

    Cyclic Pressures - What's the Difference Between Ductile Iron & PVC and How Do I Accommodate In Pipe Design?

    By Ken Rickvalsky, ENV SP, AMPP CT   07/25/2020  In Products Technical

    This entry in the Iron Strong Blog compares the performance of Ductile iron pipe (DI pipe) to Polyvinyl Chloride (PVC) pipe against cyclic pressure variations in piping systems. Cyclic loading, or more accurately, cyclic surges, is a phenomenon where pressures in a pipeline frequently vary due to changes in demand, operating conditions, storage tank levels, treatment plants, and pump starts and shutdowns. Surges can also occur during common field operations such as exercising or flushing fire hydrants or valves within the system, which can drastically change flow parameters, causing surges or water hammers.
