    Ask the Ditch Doctor - Does Internal Pressure Always Govern Ductile Iron Pipeline Design?

    By McWane Ductile   03/04/2022  In Ditch Doctor Installation Technical

    Have you ever been so taken aback by the structure of a question that your first thought is, “say what? Did they really just ask me that?” In the vernacular-sensitive world of utility pipelines, it happens more often than you might think.

    Do You Have an Iron Deficiency? Considering Health Effects in Pipe Material Selection

    By Roy Mundy, P.E., ENV SP, Assoc. DBIA   08/13/2020  In Environmental & Safety Products

    We in the United States are most fortunate, for the most part, to have access to safe, clean drinking water. Even when traveling, we are not hesitant to draw water from a hotel faucet to brush our teeth or even fill a glass to drink. This privilege is no accident.

  • Why Would High Temperatures Affect Piping Material Selection?

    Why Would High Temperatures Affect Piping Material Selection?

    By Scott Rhorick   03/25/2025  In Products Technical

    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).

  • Why Is Using the Right Design Criteria Important in Calculating Restraint Requirements?

    Why Is Using the Right Design Criteria Important in Calculating Restraint Requirements?

    By Roy Mundy, P.E., ENV SP, Assoc. DBIA   11/19/2021  In Installation Technical

    When I first started my engineering career, I was placed in charge of coordinating the relocation of water transmission and distribution pipelines to accommodate the construction of an interstate highway through a city of approximately 180,000 residents. Many times, these projects required pre-poured thrust block restraints due to the amended connections between new and old waterlines in a short timeframe so as not to leave customers inordinately out of water for long periods of time.

  • How Does Ductile Iron Pipe Go to Market? Understanding the Bidding Process

    How Does Ductile Iron Pipe Go to Market? Understanding the Bidding Process

    By Dustin Henderson   07/09/2021  In Our Company Products

    How do you go to market? This isn’t a question we get often, but it comes up from time to time. Sometimes we're asked by a vendor we work with who is trying to understand McWane Ductile better. Sometimes a candidate asks the question during an interview or a new sales representative asks while we’re onboarding. Other times we have a hard-working team member at one of our manufacturing facilities trying to understand further what and where the product they make goes and how it gets there. In this blog, we will look at the different bidding processes we encounter on a day-to-day basis that allow us to take Ductile iron pipe to market.
