  • National Skilled Trades Day – Appreciation of Those Building Iron Strong Pipelines

    By Carrie Stephens   05/04/2022  In Our Company Technical

    What is National Skilled Trades Day, and what is its importance? National Skilled Trades Day is celebrated on the first Wednesday in May. City Machine Technologies, Inc. founded National Skilled Trades Day to bring awareness to the skilled trades shortage facing the United States. The day also celebrates those who work in the trades, shedding a positive light and celebrating the importance of skilled trades jobs. Many highly skilled workers fill a multitude of careers across our nation, including construction, healthcare, manufacturing, and service industries.

  • How to Calculate Polyethylene Tape Requirements for Ductile Iron Pipe

    By Dustin Henderson   04/29/2022  In Installation Products Technical

    In my career with McWane Ductile, I've sold my fair share of polywrap, but the one thing that I haven't really thought about when selling polywrap is the tape needed to complete the installation. I'm not sure why this is. Maybe the biggest reason is I wasn't sure how much tape was required for each roll of polywrap I sold. Therefore, I wanted to take a deep dive into this subject to make it easier for people to know when ordering polywrap how much tape they need to purchase as well.

  • 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.

  • Why Doesn’t McWane Ductile Make Large Diameter Locking Gaskets?

    By Kevin Christian   02/11/2022  In Products Technical

    Locking gaskets are the industry standard for dependable, reliable, and easy installation of Ductile iron pipe (DI pipe)  in 3-inch through 24-inch diameters. Locking gaskets for DI pipe have been around for more than 30 years and have been used in over one million push joint installations. However, as good as locking gaskets are in 3-inch through 24-inch, there were challenges involved when attempting to install in 30-inch and 36-inch diameter pipe. In this Iron Strong Blog, we will look at the various reason we do not make large-diameter locking gaskets for DI pipe.

  • How to Uninstall Ductile Iron Pipe Joints that Contain Locking Gaskets

    By Doug Clark   01/27/2022  In Installation Products Technical

    Have you ever been on a Ductile iron pipe (DI pipe) installation with restrained joint gaskets and needed to uninstall a previously assembled joint? This is normally prompted by the need to replace a displaced or a “pinched” gasket. Proper gasket placement and attention during assembly is the best way to avoid such conditions, as detailed in a previous blog by McWane Ductile. Unfortunately, the problem often does not arise until the pipeline is hydrostatically tested. In today’s Iron Strong Blog, we will examine the “Dos & Don'ts" of uninstalling with DI pipe restrained joint gaskets.

  • What Are the Three Pipe Tapping Methods?

    By Josh Baker   12/27/2021  In Products Technical

    So, you have an existing water distribution system feeding a small hospital and a military post. Now you need to branch off the pipeline to feed another 30 new houses under construction nearby. How do you do it without interrupting service to the critical facilities already being served? In this Iron Strong Blog, we’ll discuss three common pipe tapping methods used in the water and wastewater industry and the variables to consider when choosing the best method for your waterworks project.

  • Why Do Pipe Foundries Have Seasonal Shut Downs?

    By Benjamin Leonard   12/15/2021  In Environmental & Safety Our Company Technical

    Customers will at times ask why manufacturing facilities are shut down. Let's face it; we live in an "I want the product, and I want it NOW world," and no one wants to hear about a shutdown. The following blog will demonstrate what occurs during a shutdown and the main reason for a shutdown which is ultimately “YOU,” the customer.

  • Why Are Thrust Restraints Not the Same for All Pipe Materials?

    By Scott Rhorick   12/13/2021  In Products Technical

    In today’s marketplace, everything is in constant flux. Projects have specific completion times, and material lead times are continually increasing. For a variety of reasons, materials that typically were in stock for immediate shipment now take weeks to months before they are available to ship. You may be considering changing the piping material to be used in your water line project to another type of material. A significant consideration is how each type of piping material requires different lengths of restraint to control the change of direction in the line.

  • 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.

  • 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.
