As a junior and senior in college, I spent a lot of time asking those I looked up to in the workforce, such as my parents, friend's parents, and professors, what I should expect from my professional career. Majoring as a mechanical engineer, I was worried I would be required to remember and be fresh on every equation or theory in thermodynamics, materials science, and all my other brain-twisting courses. Luckily, the water industry found me, and it came paired with quite a few resources to help me excel as a young professional.
What do balancing a checkbook and restraining Ductile iron pipe (DI pipe) have in common? They are both important skill sets that lead to peace of mind. A typical waterline experiences thrust forces produced by fittings, closed valves, or dead ends. These forces must be "balanced out” or canceled to maintain the pipeline’s longitudinal integrity across the joints. Similar to managing a checkbook, the weight of the pipe, the water contained in it, and the backfill above it, along with the pipeline's friction with surrounding soils, help counteract a portion of the "thrust force" bill. The remaining force must be zeroed out using a calculated length of restrained joint pipe and fittings, following the ASTM/AWWA calculation protocols.
In this #IronStrong Blog, we will explain thrust forces, how they are created in a water line, why they are important, the information needed to calculate them, and how to easily calculate them using the McWane Pocket Engineer™. Once you have those calculations, we will show you what pipe joints to use and in what quantities to make your pipeline restraint secure for generations.
Why is your bottom-line important to us? For more than three decades, I had the privilege to serve within the nation's largest investor-owned water utility. During that time, I clearly saw the advantage of a financially sound utility. Whether it be having the resources to invest in needed facilities, provide a work environment that would attract well-qualified people, or purchase needed supplies and equipment to operate the business effectively. These are just a few advantages of maintaining a strong bottom-line.
Over the last several months, I have encountered a few municipalities that have asked the question, does McWane Ductile manufacture TR Flex Restrained Joint Pipe differently than U.S. Pipe?
Thermite welding, often referred to as CAD welding, on Ductile iron pipe (DI pipe) and products is a common practice in our industry today. This welding technique of using heat from an exothermic reaction to produce coalescence between two metals is most often used to bond the Ductile iron joints for cathodic protection or for the opportunity to add a cathodic protection system at a later date. In this Iron Strong Blog, we will discuss when, why, and how to properly CAD weld on DI pipe.
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.
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.
Anyone who has ever studied or just skimmed the pages of the AWWA M41 Manual (M41) knows it helps to be of an engineering mindset to understand most of what’s within it. What if you could turn this indispensable reference into a simplified, easy-to-access tool that fits your pocket? Well, the McWane Pocket Engineer does just that! In this Iron Strong Blog, we will discuss the many Pocket Engineer (PE) components and how this real-time application utilizes important aspects of the M41 Manual to simplify life for you, the water professional.
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.
